Abstract

The mechanical and metallurgical properties of XA78S aluminum alloy clad sheet, plate and extrusions have been evaluated in this work. Long time tests will be reported in a supplement to this work. The results when compared with the evaluation by other investigators, may lead to the acceptance of this alloy as an aircraft material. The XA78S aluminum alloy has approximately 10 percent greater strength than other high strength aluminum alloys. It has corrosion resistance, fatigue strength, microstructural characteristics, response to heat treatment and spot welding properties comparable to other commercial aluminum base alloys containing zinc, magnesium, and copper.This alloy offers greater resistance to benfing therefore, the forming will be more difficult. As a result of this evaluation three specifications have been issued. The designation for XA78S, 75S and 24S aluminum alloys have been recently changed to X7178, 7075 and 2024, respectively.
