Mechanical-Property Data 7175 Aluminum: T736 Forging
Abstract
Aluminum alloy 7175 is a new Premium Strength Die Forging. This development is intended to provide relatively high strength/weight ratios for aerospace applications. The guaranteed minimum longitudinal yield strength for the -T736 temper is approximately 17 percent above the current minimum requirements of specifications covering 7075 alloy die forgings in the -T73 temper. Although the development emphasis was placed on high longitudinal strength, the transverse ductility is also well above that of most conventional 7075 die forgings. Tests on a limited number of forgings in the -T736 temper indicate that the stress-corrosion cracking threshold in the short transverse direction should be at least 35 ksi. Currently, the product is limited to closed die airframe-type forgings.
