Quantity:

Materials are the foundation of the aviation equipment manufacturing industry. Due to the special service conditions of aviation equipment, the aviation industry has extremely strict requirements for the selection of aviation equipment materials. 

Among the aluminum alloy series, 7000 series high-strength aluminum alloys are widely used in the manufacture of parts for aviation equipment due to their light weight, high tensile strength and strong corrosion resistance. One of them, 7A85 aluminum alloy, as a new type of high-strength alloy developed by China, has attracted wide attention from aviation component manufacturers with its improved excellent performance.

7A85 aluminum alloy is a new type of aluminum alloy developed in China through microalloying and heat treatment. The alloy composition is equivalent to 7085 aluminum alloy, but due to the composition optimization and processing technology improvement, 7A85 aluminum alloy has higher fracture toughness and lower quenching sensitivity, and is more suitable for manufacturing aviation parts.
