I need to build some aluminum support mounts. They need to be fairly strong since they will be supporting a 600 lb static load. Once the aluminum is annealed it seems that it will lose a lot of strength. Is that true?
If you bent the material with a proper bend radius then no need for annealing. For your 1/8" thick material a minimum bend radius of 1/4" is a good start.
Just to be sure I’m understanding you correctly. You’re suggesting that 6061 1/8” aluminum can be bent at a 1/4” radius without the need for annealing and won’t crack?
@LovelessRanch that would be a minimum. Better would be 3/8". You would have to do some testing and if you can make sure that your bend is across the grain of the material. If you have to bend parallel with the grain then definitely use the 3/8" radius.
Now that it is annealed, how do you get it hardened again for the work it is to be used for? Does it harden on it's own as it cools, or does it need heating and quenching to be hard again?
Can you do the same to flatten out, heating for the torch and sandwich between two flat surfaces? I have a bent license plate bracket that i would like to flatten back out.
It doesn't bend well because its T6. T3 would bend easier. Doing complex bends you really want O material. Then you can heat treat it after you have bent it.
Congratulations you just took the tinsel strength out of the Aluminum this will cause the piece to fatigue and break much sooner, why don’t you just use 6063 aluminum it’s more easily bent or heat and quench you finished piece
Depends on what you're doing. Shooters annealer their brass before shooting which stretches it in the chamber. They anneal before to prolong the life of the brass and prevent splitting or breaking.
Good tip but.............bolt your vise down!
Thanks for demonstration.. 👍🏻😇
Nice tip, like Bad Obsession Motorsport but with less tea.

Yes, that is true. Strength is why it was heat treated to begin with.

Why not splurge a little, and mount the vise on the work table?
I move my vise a lot. I actually have 3 different benches in my garage to bolt it to.

I think you are thinking steel.
@@lanix17 No, everything he said's applicable to a lot of metals, including aluminum.
Yeah you can heat up 1/4 alluminum. I thought you couldn't but it breaks if you don't thanks fella's. tk

Obviously just put A LOT of pressure on the whole plate for few hours to be sure

Good tip but what’s with your loose vice. Yikes man. And get a cheap brake, it’s worth it’s weight. Seriously.

Annealing is done by heat treating the material AFTER the bend.
