AL 6061- T6 Alternate

[Hclrag123]

Hi All,
I am currently working on Cost reduction of an AL 6061-T6 PLate 1600mm X 500mm X 40mm thk. This part is used in Vaccuum and is Type-3 class 2 Anodized.
Is there any other Cleanroom material alternate to 6061 so that i can reduce some cost without compromising the Strength or hardness or quality?

Any help in this regard will be helpful.

Thanks.

SST is the other obvious metal but you need to consider various factors to see if it's a fit.

Thank you Zinov and Kenat.
Will evaluate the AA2024. SS wieght will be a concern.

Hclrag123,

Take a look at something like Alcoa's QC-10 aluminum tooling plate. This material is designed as a slightly lower cost commercial alternative to some wrought 6XXX or 7XXX series aircraft alloys. In fact, I believe cold worked QC-10 has a bit better mechanical properties than your 6061-T651 plate.

Hope that helps.
