1050 aluminium 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.〔Marks' Standard handbook for Mechanical Engineers, 8th Ed., McGraw Hill, p. 6-50〕 Alternate names and designations include Al99.5, 3.0255, and A91050. It is described in the following standards:〔(1050 (Al99.5, 3.0255, A91050) Aluminum ).
