Sự miêu tả
7075 T6 Aluminum Round Bar or as also known as AA7075 is an aluminium alloy. The primary alloying element of the 7075A Aluminum T6 Spring Steel Bars is zinc.
Al7075 T6 ASME SB 211 AA7075-T651 Aluminum Round Bar Manufacturer and Aluminium Flat bar supplier RAYIWELL MFG is a professional factory of tấm nhôm, thanh nhôm, or aluminum plate in China.
7075 (UNS A97075) is an aerospace aluminum round bar with cold finished or extruded aluminum wrought alloy with high strength, adequate machinability and improved stress corrosion control. Fine grain control results in good tool wear
7075 is one of the highest strength aluminum alloys. It has good fatigue strength and average machinability. Often used where parts are highly stressed. It is not weld able and has less corrosion resistance than other aluminum alloys. The mechanical properties depend on the temper of the material. Commonly used in the bicycle industry, aircraft structures, and in rifles for the American military. We stock 7075-T651, 7075-T6511, 7075-T7351, 7075-T3511 and 7075-T76511.
