Called a DER and he says extrusions are slightly stronger! Answered my own question.. Thanks for your input though guys!

My conclusion is if the final product of both are 2024 T-3, both experience similar cold working, and the extrusion has a longitudinal grain direction at the same time the extrusion might have some impurities.

I do know that the yield strength of 2024T-3 is the same across the board whether extrusion or rolled die pressed.

Anyone have any engineering data on this? I haven't been able to find any engineering papers or tables on one vs. the other.

You should be able to find the info in MIL-HDBK-5. It is a catalog of material properties for metal.

What material was originally used?

7050 is a far better alloy than 2024 if you are looking for something stronger and you may have better luck finding that now.

You might also look into having your stringer shape milled from a larger or thicker extrusion, or even a piece of bar stock.

Would Vintage Air Works also do stainless steel forming?
