i'd like to get the stuff they use to make aluminum truck cargo bed caps.
1" square, radiused corners, thin wall, i assume not extruded, aluminum
tubing. i've used 6061 T6 tubing before and somehow this stuff doesn't seem
like 6061 T6 to me, it seems softer and more weldable. they use this stuff
to build aluminum truck caps and it has welded connections. i don't know
what it's called so i don't know where to look for it and every place i have
looked has 6061 T6 non-radiused (square) corner extruded stuff, "aircraft
grade". the stuff i'm looking for would be, i assume, NOT aircraft grade.

b.w.




Might be "architectural" aluminum - 5053 h something or other.

It it a fairly soft temper.
Cheap stuff.
