7075-T6 aluminum is 7075 aluminum in the T6 temper. To achieve this temper, the metal is solution heat-treated and artificially aged until it meets standard mechanical property requirements. The graph bars on the material properties cards below compare 7075-T6 aluminum to: 7000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it’s 50% of the highest, and so on.
7075 aluminum sheet has a high strength to weight ratio. 7075 parallels the use of 2024 when higher mechanical properties are desired. Because of this it is used for highly stressed structural parts. It is highly used in aerospace, commercial aircraft, defense equipment and components.
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.
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.
