Aluminum 630 is a non-standard or legacy aluminum alloy that may appear on older drawings or internal specifications. It’s not a commonly standardized wrought aluminum alloy under modern AMS or ASTM systems.
Is Aluminum 630 the same as 6061?
No. Aluminum 630 is not directly equivalent to Aluminum 6061. Any substitution or equivalency should be evaluated based on application requirements and customer approval.
Is Aluminum 630 still available?
Availability depends on the intended material requirements. In many cases, Aluminum 630 references require clarification or substitution with a modern aluminum alloy.
Is Aluminum 630 the same as 17-4PH stainless?
No. Aluminum 630 should not be confused with UNS S17400 (17-4PH stainless steel), which is a completely different material.
