Alloy 7075 has been thoroughly evaluated for corrosion resistance of atmospheric weathering, stress-corrosion cracking and exfoliation in all currently available tempers. These values have been used as a standard for comparison in the development of more recent high strength aerospace alloys and used for highly stressed structural parts in the aerospace and defense industries, and as mold material in the plastics industry. Main application and uses for Aluminum alloy 7075-T7351 are: Aircraft fittings, gears and shafts, fuse parts, meter shafts and gears, missile parts, regulating valve parts, worm gears, keys, aircraft, aerospace and defense applications.

7075 aluminum sheet is one of the highest strength aluminum alloys available Its strength-to weight ratio is excellent and it is ideally used for highly stressed parts. It may be formed in the annealed condition and subsequently heat treated. Spot or flash welding can be used, although arc and gas welding are not recommended. It is available in the clad form to improve the corrosion resistance with the over-all high strength being only moderately affected. Applications: Used where highest strength

An aluminum alloy best suited for aerospace and aviation applications is 7075 T651. This tempered alloy has a high tensile strength which makes it particularly applicable for certain high-strength applications.
