Aluminum Alloy Die Forgings (7175-T66) Solution and Precipitation Heat Treated AMS4148D

This specification covers an aluminum alloy in the form of die forgings and forging stock.

These forgings have been used typically for parts requiring a high level of mechanical properties, but usage is not limited to such applications. Certain design and processing procedures may cause these forgings to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.
