Previous Home Brinell test for hardness pegged this aluminum as 5052 H36 with a yield of 29 Kpsi...
I am getting ready to use some of this in a critical location so I decided to do another couple of tests....I did two tests the with a large yield as shown in the picture of 38 Kpsi and a very slight deformation maybe less than 2 deg at 27 Kpsi.
If you have some aluminum that you are not sure what it is, you can use the cheap hanging scale, (load cell) and a drill press to do your own Brinell test. The pictures say it all and the handy link to a calculator makes it really easy...
