Product Code:SAE AMS4123
Title:Aluminum Alloy, Rolled Or Cold Finished Bars and Rods (7075-T651) Solution and Precipitation Heat Treated
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope: This specification covers an aluminum alloy in the form of bars and rods.These products have been used typically for machined parts subject to excessive warpage during machining due to residual stresses and for parts requiring high strength and whose fabrication does not involve welding or forming, but usage is not limited to such applications.Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.
