Both 7075-T6 aluminum and 7075-T7 aluminum are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing. There are 31 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

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.

6061 T6 Aluminum Sheet is an aluminum sheet product that is very versatile and has a wide range of applications. 6061 Aluminum sheet is made from one of the most widely used heat treatable aluminum alloys. This sheet has excellent corrosion resistance, good workability and good machinability. 6061 sheet applications include a wide variety of products from medical assemblies, aircraft construction to structural components. 6061 t6 aluminum sheet has a high strength to weight ratio making it ideal for any application where parts need to be light.
