7075-T6 Aluminum Flat & Square Bar

7075 is one of the highest strength aluminum alloys available, often used for highly stressed parts. It has good machinability and an excellent strength-to-weight ratio, and is a popular material applications where strength is extremely critical. 7075 has only average corrosion resistance. Improved resistance is normally obtained by cladding parts. AED stocks 7075 in many bar and plate sizes; sheets and other sizes are available upon request. 7075 is sometimes used in place of 2024.
