Aluminium 1050

1050 Alloy is an aluminium-based alloy in the “commercially pure” wrought family (1000 or 1xxx series). As a wrought alloy, it is not used in castings. Instead, it is usually formed by extrusion or rolling. It is commonly used in the electrical and chemical industries, on account of having high electrical conductivity, corrosion resistance, and workability. It has low mechanical strength compared to more significantly alloyed metals. It can be strengthened by cold working, but not by heat treatment.

Alternate names and designations include Al99.5, 3.0255, and A91050. It is described in the following standards:

  • ASTM B 491: Standard Specification for Aluminum and Aluminum-Alloy Extruded Round Tubes for General-Purpose Applications
  • ISO 6361: Wrought Aluminium and Aluminium Alloy Sheets, Strips and Plates

Typical Applications: Chemical process plant equipment, Food industry containers, Pyrotechnic powder, Architectural flashings, Lamp reflectors, Cable sheathing
