1050A Aluminium Alloy is a "commercially pure", wrought alloy type with good corrosion resistance, high strength, high ductility, and a highly reflective finish. This alloy it is not used in castings. Instead, it is usually formed by extrusion or rolling. 1050 has low mechanical strength compared to more significantly alloyed metals. It can be strengthened by cold working, but it cannot be heat treated.
T4 is the commonly used tempering process for this alloy. The alloy is solution heat treated and naturally aged to gain a very stable condition.
Alloy 1050 (1050A) is typically used for chemical process plant equipment, food industry containers, kitchenware, pyrotechnic powder, automotive industry, heat sinks, architectural flashings, lamp reflectors, cable sheathing and general sheet metal work.
