Aluminium / aluminum is a ductile, silverish white metal that is never found in its metallic form in nature. It occurs as bauxite, which is a mixture of aluminium oxides, iron oxides and clay.

Aluminium / aluminum alloys are extremely useful low-temperature alloys. Aluminium / aluminum 1050A alloy is a wrought alloy type with good corrosion resistance, high strength, high ductility, and a highly reflective finish.

The following datasheet will provide more details about aluminium / aluminum 1050A alloy.
