Is it 2024-O, 2024-T3, or 2024-T351? (The latter being heat treated versions of the 2024 alloy, 2024-O being not treated).

I'm not sure what tests were run, but the heat treating would make a difference in the yield strength of the pin (by nearly a factor of 2).

Here's a bit on 2024 alloy.

The test that was performed just told the alloy. The local scrap yard has a gun that you put it aginst the metal and pull the trigger and it tells the alloy on the screen. It has no way to tell heat treatment. I had to hammer the pin flat to get a reading on the machine and I can tell you it seem softer than most AL I've ever delt with ( I know, not very sciencitific

).

I'm thinking maybe I could get a piece of 2024 of the same dia. of the pin and drop a wieght from specified hieght on both and check the deformation of both after the test to see if they match (I'll know the heat treatment of the new AL). What do you think?
