- Solder on aluminum - Solder electronic components & wires to aluminum surfaces. No need for screws/bolts. Useful for example for aluminum RF shields and heat sinks. Also suitable for plating aluminum objects for artistic purposes.
Process is electroless (non-galvanic copper plating) and uses very common easy to find chemicals.

Very cool. Now I can solder on to aluminum cans, and also cover up silver solder on copper jewelry. Love it, thank you!!
Ha! Excellent idea, to cover the aluminum with copper... Thanks for this great idea!
I did this on some machined 6061 and then did an electroless tin plate over the copper. It worked pretty well. The places that it didn't plate as well were places that were harder to mechanically clean (i.e. sand) beforehand. If I could, I'd sandblast and or acid etch prior. Also, I wear gloves and wash up well when using copper sulphate and ferric chloride.
this will work perfect for soldering to my aluminum antenna for noaa sat TY!!!!!!
This is awesome. I used to just put a drop of motor oil when I needed to solder to Alu.
did it work?
hello dear I have some issues. I have LiFePo4 cell it's terminal are aluminum based I Wana series it through copper bus bar and soldering can you give me some tips because when I sold on it after connecting load the soldering got melt
1. Do not call anyone 'DEAR'. This is offensive in the West. It does not translate well from Urdu or Arabic or Hindi. Stick to just Hi or Hello.
2. Note that solder comes in different heat strengths. Leaded solder melts at lower temps. Non-leaded melts at higher temps. There are also other solder temps used in jewelry.
If your solder is melting then use a higher temp solder like a non-leaded one. If you have to solder repeatedly on same object, then start with the highest melting point solder, then medium, then low melting point. This is what they do in jewelry making.
what is the fecl3 Concentration and solvent?
Thanks man this genius idea 💡
Great result! I could even plate Aluminum foil with ease..
Good job, SimpleTronic¡¡¡¡ Congratulations since Spain¡¡
Umarım yayın yapmayı bırakmazsınız. İlk defa gördüm. Kalın malzemede yapmayı deneyeceğim. Başarılı olursa kendi kanalımda da yayınlarım.
You are a maestro!
thanks sir very helpfull
Good job
Very gooood idea , thank you for sharing
Great idea, you are the master, thanks for all your video, especial for this and sponge etching is excelent
Nice, thanks :)
Thanks! This is exactly what i need! !
Interesting.
Great usefull video thanks for sharing
good tutorial, very useful.
Hydrochloric acid also works
brilliant !
Thanks for sharing
What if you can't get ferric chloride? Some governments are really tight on chemical sales? Good video and thank you!
I tried it first without and that also worked. But with the addition of Ferric Chloride initial reaction takes place fast and more strong.
For solderin You can use a product called Alusol. It works fine provided that You can heat the object properly.
I made a video on soldering in the hobby workshop.

what is the concentration of fecl3 solution ?
I think you just buy it at a preset concentration.
That is terrific. I shall try it!
Woww.... 🎉💖💖😊
The choice in the Aluminum alloy is very important. almost pure 1xxx like 1100 is OK, 2xxx like 2011 contains copper, lead and bismuth 2024 contains copper, manganese and magnesium can you solder these? Can you solder 3xxx like 3003 which contains Manganese and copper. 5xxx like 5052 Manganese and chrome 5083, 5086 manganese, magnesium and chrome. can your solder these? 6061 magnesium, silicon, chrome, and copper and 6063 magnesium and silicon I had 6061 T6 part first plated with copper and then silver to make bus bars for a power electronic compression bonded Darlington twin stack switching 1000 amperes. Marginal attachment. I was told because of silicon. can you solder 6063? NOTE: metals are listed in Mc Masters Carr.
great ❤
I imagine this would also work with aluminum chloride instead of ferric chloride, which is good since aluminum chloride is somewhat less toxic and reactive. It may also help to add corrosion inhibitors
Did u try this on lipo battery tab? Did it work
This is what i want to do.
Use ZnCl2 (Zink chloride)for lipo cells . It works 💡👍
Great video. Thank you.

Excellent! Thanks a lot.
Cool. What's the ratio of distilled water (was it distilled?) to copper sulfate?
Thank you.
God bless, Rev. 21:4
Hi! i used ordinary tap water. Just shake until no more CuSO4 dissolves. (at room temperature) Thanks :-)

I believe you can use Vegetable oil. You'll need to see what solder works best with it. If this works for you. Just look how much you save in time and money.
I've been hearing about using vegetable oil
or just cooking oi
i hope someone would make a video about it
@@erklid2882 There is a product called Alusol. This stuff has flux that bites through the aluminium oxide.
I made a video on soldering diverse material including aluminium.

You smart
Hi, to everyone wondering if this will work on aluminum heatsinks, yes it works very well. I was able to manage to copper-plate a regular 100mmx40mm aluminum heatsink using this method, and solder on a heatpipe into it. But the process is not that easy. You have to be very patient in applying, and you should only apply a thin film of copper sulphate and ferric chloride solution on top of the other until you have a noticeable and thicker plating. Don't apply too much in one wipe or else, it will only have a black goo and no plating. The copper plating I managed to do can hold up to a bit of force if it's thick enough, and it also works as far as cooling is concerned. A very thin layer will just get chipped off like paint.e
This didn't work very well in my case. I suppose it's easier when you're soldering a tiny little thing where the heat has nowhere to go, but when working with a larger aluminum piece, it's hard to get it to be warm enough. That's why I was hoping that chemistry could work... but the copper doesn't stick very well.
Very cool :)
Wait.... did he just show me how to do copper plating!???
It's not copper !
It is a chemical burn the removes the upper plating.😂
Hey @SimpleTronic, an the same steps can be done to an aluminum heatsink? Im looking into soldering a copper shim on a aluminum heatsink, but so far have only found this video: ruclips.net/video/LWcBZhI-Oxo/видео.html
I managed to do this to an aluminum heatsink, in case you are still wondering. Only needed a thicker layer, and some patience doing some trial and error.
not work
hello.p;ease give me your mail.thanks
