Aluminum Elongation for 3004 H22

[Albigger]

Hello,

We are looking at an application of subsequent forming of aluminum tubes, 3004 alloy, H22 temper. Where can I find elongation data for this material?

The approx geometry will be about 6" diameter x .030 inches thick wall (before forming).

If needed, can we anneal the part before forming to the O condition to provide better elongation for forming? Or can we increase formability some other way?

Thanks.

How about using h32 as your reference? They are both 1/4 strain hardened. I have seen 10 or 17 prevents for elongation for h32.

Albigger,

How are the tubes being manufactured? Is the raw material 0.030 inch thick 3004-H22 that is subsequently rolled into a tube shape? Or something else?

ASTM B209 is the North American standard for Al sheet. The requirement for elongation in a 2 inch gauge length specimen is 3% minimum for a thickness of 0.030 inch.

Yes, they are being rolled and welded from coil.
