You don't even understand what you are talking about.
Did they test it with a bandsaw blade?
Protective membrane for spacefaring ships which inevitably are bombarded by copious foreign objects which could at anytime pierce the hull or any key support area of the ship letting the vacuum of space in to wreak havoc and ultimately death of the crew and mission. Highly ductile composites such as the one focused on in the video definitely could help in futuristic shield systems. Advanced tech generating magnetically repellent fields layering a nigh on impenetrable metallurgically enhanced super-composite could definitely play a key role in future space flight.
Can anyone tell me if we add a bunch of ceramic balls, rubber and metal flakes into the foundation of a building or house, would that help against earthquakes? Or at least keep the foundation from cracking under normal circumstances.
@@mikebar42 Yes, it would actually help make the foundation less likely to crack, although, you could do without the metal flakes, and, instead, put metal rods.
Alright. I'm with you on the grinders, drills and such...
But back to the bike lock example... how would this material hold up to bolt cutters when it's about the diameter of a bike lock?
it would be interesting to see because the size of the ceramic would be rather small. I wonder if someone could make and test this?
it wouldnt, would also fall apart immediately on contact with plasma or oxyacy torch, its just a cute exercise in futility that can break most powertools
Well if ya think about it who's gonna try and steal a bike with a plasma torch? Seems a bit overkill for a bike
@@dinf8940 I would imagine the real use for this is in vaults and armored doors, not small portable things. I also wonder if they could somehow replace the aluminum with steel or titanium. Also i so guess they say it is "cut" resistant not melt resistant.
@@JWhiteley unless the bike is 6 grand
SciShow: Uncuttable Material!
LockPickingLawyer: Today we’re using a strip of aluminum from a Redbull can.
@ArmchairWarrior Can't always win >blows on finger tips< :)
@@dalleth did you burn your fingers?
I do notice they didn't talk about using actual bolt cutters (or the big hydraulic cutters that LPL tests chains with), nor did they show a test against very rapid impacts (Ramset gun, anyone?).
@@ConstantlyDamaged Or, y'know, just a hammer and chisel. I can see how it would be hell on rotary cutting tools, but it sounds like it'd be pretty soft/brittle if you just beat on it. And the sample videos having it in a steel box are a bit eyebrow-raising, makes it look like they're hiding something. Clearly we need Gavin Free to rent a tank again.
oh hey! what's up profile picture buddy?
"This material is nearly uncuttable"
What is anything I'm working on in the garage, Alex
If it's ceramic and foamed aluminum, I have to imagine it's pretty light too. That seems like a ridiculously useful substance.
well it what the mechs in battltech uses so they be pretty hard to get thew
Someone Better Suggest Elon Musk To Use This Material On Twitter, I Bet He Could Use Some Of That Material For His STARLINK Satellites And Space Rockets.
If This Material Is As Strong As The Researchers Claimed It To Be, We Should Put Them To Good Use Against Space Debris(Which Are Deadly Against Spacecrafts And Satellites).
Until you melt that foamy aluminium with any kind of (portable) blowtorch. Aluminium melts at such a low temperature…
@@Runoratsu but that could be changed by mixing other substances into the alloy, right?
only thing would be find a material that elevates the aluminium fusion point without messing with it's foaminess property
+@@Runoratsu I Don't Believe Any Random Person Could Fly Into Space And Use A Blowtorch To Sabotage Satellites Or Space Probes And Rockets Anytime Soon.
Plus, If That Material Is Going To Burn That Easily... It's Perfect! STARLINK Satellites Are Going To Be Built Specifically To Burn In Earth Atmosphere When They Fail.
Not Only That, Proteus Are Also Capable Of Withstanding Ballistic Projectiles Such As Bullets, Which Means High Speed Space Debris Cannot Sabotage And Penetrate Through Satellites Made Of Proteus.
On A Side Note, Once I've Checked The Source Materials Cited In The Video's Description, It's Only 15% Of The Density Of Steel Based Materials That Are Currently Used By Space X. Imagine The Amount Of Cost Elon Musk Could Save From Launching Those Satellites Built Out Of Proteus Composite With It's Light Weight Features! Another Plus For The Project.
Though, The STARLINK Project Have Already Started And The Manufacturing Process Has Begun.
So, I Doubt This Information Could Be Useful For Elon Musk. Though, It Would Be Useful For Those Who Wants To Start A Company And Launch Satellites Of Their Own, Of Course.
This is the same realm/concept as how composite-armor plating on modern-day tanks work.
Well that’s because tanks use composite armor. Composites are nothing new. The composites used on modern tank armor is very different from this type of composite. Tanks use a simple layers of different materials with different properties. Usually something hard (steel, ceramic, or depleted uranium) and something more elastic like plastics or fibers. They also have ablative armor that can explode outward to mitigate the effects of high powered projectiles especially explosive projectiles. Composites are pretty cool. Even messing with the idea at home or in the garage can be mind blowing.
@@MisterRorschach90 ok?
@@MisterRorschach90 I mean you didn't have to go into this detail the guy never said composites or new, and actually depleted uranium isn't on the armour it's used in tank shell to PENETRATE armour
@@Hazed64 I’m sorry buddy but I know what I’m talking about. Depleted uranium has most definitely been used as a component of tank armor. I don’t mean to sound like a know it all or an ass hole. I’m just right.
@@Hazed64 Depleted uranium is actually used in US Abrams tanks as part of the composite armor.
So, uncuttable with an angle grinder. There are many ways to skin a cat, and I'm thinking plasma cutter or cutting torch should work good
Yes, plasma cutter or water jet. Oxy propane cutting torch uses an oxygen jet to burn away the steel which wouldn't work on this material.
@@adamwhiteson6866 They tried a water cutter on it, no dice.
Nothing can stop a torch
Does it still count as cutting if its a liquid?
Ah, but what's legal in Robot Wars? Light weight... should go on a robot nice and easy.
Of course we don't know how it holds up to being hit repeatedly with something heavy.
I’m sure other people have pointed this out but concrete also has water, air, and additives (in addition to the aggregate, aka “rocks and sand” and cement) that are extremely important to the mix design. The cement and the water react and as the cement hydrates it basically creates a net that holds the aggregate. The aggregate typically makes up the bulk of the mix and provides the majority of the strength but you do not have concrete without water. Cement on its own is just a powder.
As a material science student, I approve of all the recent material focus 😊
Pain from stepping on a lego brick should be sharp enough to get through it.
Anime swordsman: "Finally a worthy opponent"
I think I'll pass on an uncuttable bike lock, thanks. I've lost my bike key once. Was glad that the repair guy was able to cut through the lock, rather than having to go through the bike.
Okay, but what about when constant pressure is applied? Such as with a bolt cutter or a hydraulic press?
I am kind of surprised that this didn't already exist, seeing as we have been experimenting with reinforcing structures in different ways for a long time. An example is concrete bunkers as cement reinforced with steel bars.

It sounds great, but I dunno if it would actually be good for preventing thieves from using bolt cutters to steal your bike. From the sound of it, the material's defense relies on the cutting tool to be moving very fast and/or vibrating. Neither of which are things that bolt cutters do. Bolt cutters are mostly just applied leverage and a strong cutting edge.
Have they tested the material against slow moving non-vibrating cutting methods?
That said there are ALOT of situations where fast or vibration forces break or disable the things we build, so it still sounds like a great thing. I'd also like to see it tested against weaponry. Explosives, small and large caliber weapons fire...
Sounds like what can’t be cut is the ceramic....and anyone that’s tried to drill or cut ceramic coulda told you that.
exactly what i was thinking
I believe it's the incorporation of ceramic hardness into something less brittle that makes it a promising material for security applications. You couldn't have a ceramic safe for instance because while it would be really difficult to cut/drill you could (theoretically) just smash it with a hammer, alternatively you might be able to make a metal safe which is resistant to being shattered with impact tools but the softness of the material makes it vulnerable to cutting/drilling. Having the two materials combined into a single product would be useful
@@DjDolHaus86 you mean like most composite armor of today except more expensive?
@@DjDolHaus86 That's what the host should have explained. He kind of missed the mark when he opened with an attempt to explain "composites".
@@midgetman4206 not quite. Composite armour is like existing safe design where you have separate layers of different materials designed to do different jobs. Composite armour has ceramics to fragment and take the high energy out of a projectile and then fibres to catch the low energy fragments. This design is fine for stopping single, high energy attacks but loses effectiveness to follow up hits but this would be no good for something like a safe where it needs to stop or slow persistent attacks.
The price really isn't an issue because what you're storing inside the safe/vault will be of equal or greater value. Don't be under the impression that this product is supposed to be invulnerable, like fort knox it's just supposed to be so difficult to get through that it makes for a poor target for would-be thieves. Any lock or material can be defeated with enough time and effort, whether that effort is worth it depends on the prize and the cost for being caught trying to get to it.
As a mechanical engineer, I doubt that vibrations play a large role. Ceramics are strong enough to do that all on its own; those balls are massively hard, if brittle. The aluminum foam probably just holds those balls in place; adding in some flexibility and shock absorption. Then the balls are going to be harder than nearly everything but diamond and wear down any cutting tool.
But, this isn't going to stop crushing forces like bolt cutters; scaled down to a padlock size, the bolt cutters would just shove the ceramic balls out of the way. And I also wonder if they could simplify the process by filling a mold with balls, then injecting an aluminum alloy directly into a mold. That way they wouldn't need a steel case or the foaming agent.
The blades wore down because ceramic is too hard for cutting wheels intended for metal.
If the ceramic spheres had the same resonant frequency as the blade I think the blade would’ve shattered. That being said two random objects having the same resonant frequency is highly unlikely.
This sort of reminds me of the movie: “The Man in the White Suit” (Starring Alec Guinness). Our hero invents a fabric that’s indestructible, but since you can’t cut it, you can’t tailor it. Once they figure that out, they make a suit out of it, but they can’t dye it, hence the suit is white. It will be difficult tao make anything out of Proteus if it can’t be machined or forged.
Just put the raw materials into the mould. Problem solved. Materials like this will only really be used in special long term cases so recycling isnt a major concern.
@@VoxelMusic Easier said than done. That means you need a specialized mold for every application. Note that I said it would be DIFFICULT, not impossible. I think your post concedes that working with this material will be a PITA.
@@fredblonder7850 Carbon fiber products are sometimes made with molds, too.
@@snapcracklepop7828 Once again, I don't clam the material is useless, or cannot be worked, just that it presents some challenges. I also wonder how well it works as an abrasive on other materials, or whether it can be used to cut itself.
Imagine the proteus metal being coated with a layer of line-x, and another layer of starlite. That composite would be the most indestructible object known to man!
scientists: this material is uncutable
jeremiah with his grandpa's clapped out rosebud torch: allow me to introduce myself
So how are we supposed to shape it? Make each piece to size, or cut it with a thermal lance or laser?
I'm curious because in general angle grinders have trouble getting through titanium itself. You need a stone blade to cut the ceramic. So I'm not surprised a grinder wasn't that affective. That's like trying to cut a lock with a pair of scissors.
Making science fun for the World!
And inspiring.
Great journalism
So a low-speed disc with a diamond edge might work? Would changing the disc let you get further in? Someone determined to get through it (if, for example, it was the material a safe was made of) would most likely go with a whole host of spare discs.
i was thinking about how to make a mailbox in an uncuttable material before watching this video- i figured steel tube with concrete inside that i add a bunch of crushed ceramic into. apparently im on the right track.
I would really like to see this material as a building material. It would fit nicely with my ideal for a hardened house.
This is truly the century of material science.
It really should be titled very difficult to mechanically cut material instead of uncuttable material. We can still cut through it with chemical reactions maybe thermite or something similar or lazers or something else, there are definitely options to cut this stuff. I was surprised that a water jet cutter has so little effect, I figured it would do quite well to be honest.
So can we make Space Marine armor with it?
@Daniel Fattakhov Alright
I see your new space marine armour and I raise you a spoon made from genestealer claw.
No because it is a copyright term and you would get sued. Besides which regular marines could do with it.
I notice they didn't try anything with extremely high hardness, like a diamond blade. I also suspect that it would not hold up amazingly well to something like bolt cutters, if it were made thin enough to be useable in a bike lock.
Oh hell. Don't tell the engineers at my company. They'll start designing parts of it just to make my job harder.
Cant wait for us to make 8ft super berserkers so we can clad them in oversized armour made of this.
I'm waiting for organic bike locks that digest whoever tries cutting them to steal the bike
@2:48 so the slow blade penetrates the shield? and @3:19 this stuff is so MARVELously tough because it VIBRATES ... so maybe instead of proteus they should call it VI....... ?
in 5 years time: Bike thieves standard equipment: Laser cutter CNC machine
i cant help but think the ceramic spheres stopped the grinder because they were using a metal blade instead of a masonry one. Same for the drill bit that was shown in this video.
I'm curious how it handles impacts, especially when cold. A lot of the material should shatter, but the forces should be well dispersed with the voids and different materials. Also, if I remember right aluminum is weird in that it gets more brittle when it's hotter instead of colder.
However there is no guarantee that the brittleness will be retained in foam form, as part of a composite.
So you're saying that this material kind of um, bites back when bitten.
Also, if the speed at which the cutting disk was moving contributed to the resistance of the material to being cut...does this mean a slower moving blade would have penetrated more deeply, or just taken longer to get to the same depth of penetration?
All in all a very fascinating shiny new thing for science to play with!
That's cool but I'm not feeling the name.
Just call it shapeshifting armour. ;-)
Titanic 2: Even More Unsinkable
were getting closer to make science-fic to reality.. I love it
2:44 - Wonder why they didn't use a diamond cutting disc?!?
Bring me my gallium, let’s test the ALUMINUM composite
Let’s try a depleted uranium round , that’s the holy grail of cutting devices.
Send that material to that Finnish Hydralic Press Channel guy.
We'll use this material to fight the white walkers who will attack us in December
I wanna know the ballistic properties of this material. If it's nearly uncuttable, it's probably extremely good armor for super light personnel carriers, or powered armor.
Need to see the laser cutter results for this.
It'd be nice to have a humvee that isn't two tons over its operational limit.
Wait until it's on tank armor and body amor.
Make like the Mandalorian armor to keep light but strong armor, or grey Stormtrooper armor requiring weapons besides small arms fire to defeat them.
Did you try a diamond cutter, like for concrete cutting?
Ok so to get thru it we just put gallium on it or just use a small torch and melt the alluminium?
But did they try using shears, where cutting is combined with compression? That’s very different than a spinning blade, and a more common way to break a bike chain
I did not hear them say anything about using a cutting torch....
like bulk cutters or other slow high pressure
It's Scishow Bob!
I lost my train of thought when he said penetrating load.
So... how do you make stuff out if it other than molds?
they should have used high heat diamond cutter instead of just regular metal cutter
See, this is why i always carry my handy dandy pocket-sized wire EDM machine.
Am I the only one who's thinking about the process going to be needed for the repurposing of these so called indestructible material?
Have them try it with sabot AP tank round?
I want to know how it holds up against a laser cutter or a bolt cutter.
40k fans: *HEAVY BREATHING*
Super light, super strong, send a few dozen tons to japan. Time to build a real gundam!
its a good layer to add to underground bunkers
So basically it's an exotic Damascus
What happened when they tried an oxy-acetylene cutting torch?
you cant cut aluminum oxide with aluminum oxide, but you can cut it with good old diamond blade or even carbide drill.
That power drill they were using was too big and was rotating way too fast. Judging by it it was about 15mm thick, a thickness you shouldn't start with on most materials in the first place, plus there were no or drilled smaller hole for the big one to center on. On really hard materials what you'll want to do is to start with a small drill and work your way up and use a good amount of cutting oil or coolent, as to not wear down the drill or harden the material even further.
I wonder how it would do against shearing forces, just hydraulic cutting shears. Seems like they only testing against high-speed cutting methods.
black colour absorbs heat better/faster. question: does it means it absorbs cold better/faster too ?
Hard to cut but since it's mostly aluminium I bet gallium would still destroy it, also how would it fair against rigid cutters like bolt cutters or tin snips?
Being mostly hollow pockets I doubt it would hold up against impacts very well either. Sounds like it's hard to cut but would be too brittle for most applications
Warhammer enthusiasts might call this Ceramite !
So.. we basically invented realistic adamantium
What about a table saw or blade meant to cut through cement?
Imagine if gloves or boots could be made with material meant to burn down or dull blades fast enough to react and protect from personal injury?
Yeah you gotta buy a new blade, but if it saves my fingers I'll buy as many as it takes lol
Get matt to shoot a plate of this stuff on demolition ranch
Abrasive water jet will cut easily, as composites come apart at the crystalline level.
So you have a metal-ceramic material that has vibrations being the main reason why it's so tough and they didn't call it vibranium?
they didn't try shooting it? have these researchers never seen a youtube video?
Does this mean it is impervious to being cut mechanically or is it somehow immune to cutting by lasers, plasma, or water?
Wait a minute..
Try... 1000 watt co2 Laser cutter
Or
Try.. chemical laser 😂😂
Steel has a quality number.
So steel 0000 is fine steel.
Steel alloy is combinations of iron, other metals and solids.
....
The advance composite may be durable and have high tensile strength. But how much could it rest and against something more thermal (heat) related.
.....
This material could be used for like buildings.
But if you were to let's say on aircraft. It would be too heavy and probably snap from the fluctuation (tensile stress).
.....
Sounds like they found yeast for baking metal
as long as it doesnt need to be done quickly, mercury and gallium turn aluminum into mush
Did they try a band saw or a plasma cutter?
Safes would like to use this.
A material that vibrate making it stronger and they did not name it vibranium. I am very disappointed.
What about some high pressure water?
NGL would run ballistic tests
I bet an axe would still get through
what if they also make the grinder blade with Proteus?
13mm ceramic spheres ... this will not be used to make a lock, then.
Game changer for a space elevator?
This doesn't technically seem very difficult to make. I feel like this or something similar must have been tried before.
I guess it's time to get out the oxygen Lance
One component is steel in the list of ingredients, but is not used in the manufacture process? How is this a component?
Great description of the physics
I want this as a bike lock
