7075 aluminum wire is a high-strength, heat-treatable aluminum alloy from the Al–Zn–Mg–Cu series (7xxx series). It is well known for its ultra-high tensile and yield strength, good fatigue resistance, and excellent machinability. Compared with 7050 aluminum wire, 7075 provides slightly higher strength, making it ideal for aerospace, military, high-performance automotive, and other demanding structural applications.
Description
