Relation of Aluminum 6061-0 to AMS 4025 or AMS 4027

Douglas E. Purdy

Quite Involved in Discussions
We have a customer print that has the "Perforated Aluminum per AMS 4025 or AMS-QQ-A-250/11 (6061 -0) and a thickness of .040 +/1 .003." Now AMS-QQ-A-250/11 has been cancelled [**CNCL S/S BY SAE AMS 4025, AMS 4026, AMS 4027 AND ASTM B 209**] When I read AMS 4025 or AMS 4027 I am not able to gather what the tensile requirements are for 6061-O. What am I doing wrong?

Thanks,
Douglas E. Purdy

"Perforated Aluminum per AMS 4025 or AMS-QQ-A-250/11 (6061 -0) and a thickness of .040 +/- .003."

You have -0 condition at a nominal thickness of .040

Per AMS 4025
3.3.1.1 Tensile Properties in the Annealed (-O) Condition Shall be as shown in Table 2.
