7075 Aluminum Bar and Rod

Grade: 7075

Size:

Cold drawn: 2mm-12mm

Extruded: 6mm-400mm

Standard: ASTM, AMS, BS etc.

7075 is a high strength aluminum zinc magnesium copper alloy widely used for aerospace and demanding mechanical components. Bar and rod in T6 or T651 offer high strength and good machining performance. Overaged T73 or T7351 trades some strength for improved stress corrosion resistance. Surface protection and service assessment remain important in aggressive environments. Critical assemblies generally use mechanical joining instead of conventional fusion welding. Product route, section size and test direction influence the properties accepted for a particular order.
