SAE AMS 4141E:2000 pdf download Aluminum Alloy Die Forgings 5.6Zn – 2.5Mg – 1.6Cu – 0.23Cr (7075-T73) Solution and Precipitation Heat Treated
1 . SCOPE:
1 .1 Form: This specification covers an aluminum alloy in the form of die forgings and forging stock ordered to inch/pound units.
1 .1 .1 MAM 41 41 A is the metric version of this AMS.
1 .2 Application: These forgings have been used typically for parts requiring good resistance to stress-corrosion cracking but with lower strength than AMS 41 39, but usage is not limited to such applications.
2. APPLICABLE DOCUMENTS: The issue of the following documents in effect on the date of the purchase order form a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been canceled and no superseding document has been specified, the last published issue of that document shall apply.
