Material Notes:
Alcoa introduced alloy 7055 in the -T7751 temper for plate and the -T77511 for extrusions in 1991. This alloy was developed for use in compression-dominated structures (such as upper wing structures, horizontal stabilizer, and keel beams) and provides advantages over alloy 7150 in compressive and tensile strengths while maintaining other important properties such as fracture toughness and corrosion resistance.Information provided by Alcoa.
