What is the referenced standard for the material? What are your PO requirements? (example: HT 7075 T0 per ....etc.)

Thanks for responding. The specification is:

Heat Treat 7075-0 to 7075-T6 Per SAE-AMS-2770
AMS-2770 H

Para 4.3.1.3 Other Alloys or Other Tempers

Each lot of parts shall be hardness and conductivity tested. Testing shall be in accordance with 4.3.1.3.1 or 4.3.1.3.2

See those 2 paragraphs - specify on PO which one you want to apply (both request hardness testing).

Hardness results shall be as per AMS2658 (which I don't have).

For 7075 T0

Rc B 22 max
Conductivity 44-48

At 47-60 it looks like you are high on hardness for this temper

For the T6 temper the hardness is 84 max for the anneal condition and min for everthing else

Matweb is telling me that the conversion from the Brinell Hardness Value is 87 Rockwell B form 7075 T6 Aluminum. I am not sure what 84 max for the annealed condition means.

What I really need is a book or website that goes over the basics and includes this information. Don't get me wrong as I really appreciate your help but I am a novice with this material and need to get up to speed on it, at least for the verification aspects of it.

In that case, go after this:
