Topic: project with aluminum - question about bending

[greenjeans]

I have a 1/4" piece of 5056 aluminum that I had a friend cut into a shape for me on a waterjet.
Basically, I'm trying to make a butterfly type steering wheel for a gravity/coffin racer.
All I need to do is put 2 45 degree bends in it.   I would need to heat with a torch ?    After bending,
would I need to reheat it ?

Aluminum you can heat and bend and let sit and it will get hard again over few days.

Edit:  this particular Aluminum is non heat treatable:

You should be able to bend it cold.

I used before 2x4 clamped to the edge of the table as a poor man's break - the metal piece is between the 2x4 and table and the bend is made over the table's edge.

You should use a metal break to get the best (preside) results.
Just take it to a sheet metal fabricator. Even heating and ventilation fabricators can do that. They'll bend it in minutes. Likely won't cost you anything either.

I have access to a torch and a brake.   Since that metal is "non-heat treatable"   I should just be able to put it in the brake and give it the bends ?      I was afraid it would crack or just break.

You got a scrap piece to try it first?

No heat required. It won't crack or brake.
Have fun.

Some say it won't break, some say it will, but if it were me, given that your material is 1/4" thick, plan on a radius at the bend, twice the thickness to be safe.

Give me a break guys,
Use a BRAKE to bend material
too sharp a bend and it will BREAK

I use to bend electric boxes out of aluminum all day long it is a soft metal and will be fine in a break

1+ Also, it will work harden when bending.

You guys are over thinking this.
It isn't rocket science.

Bend it with 2x4s in the vise.. And yes sharp radius can break it, if you are bending 6061 you have to use 2.5-3 times thickness as the radius... Not the same as bending the thin box material..
