Aluminium 7005 Data Sheet

7005 Overview

7005 is a heat treatable high strength alloy with excellent corrosion resistance and excellent weldability with a structural surface finish. The higher strength of 7005 is ideal for structural applications particularly in marine and transport.

Density of 2.78g/cm3

Common Applications

7005 has a higher initial and welded strength to 6xxx series structural alloys and is preferred in large and complex extrusions like load bearing members for road and rail vehicles.

Welding

7005 has excellent weldability by all standard methods including GMAW (MIG) and GTAW (TIG). Filler alloy 4043 is the primary filler though 5356 wire is the suggested alternative.

Machining

7005 has good machinability.

Similar Products

Structural alloys 6082 and 6351 are alternatives to 7005 though they have lower mechanical properties.
