Introduction
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.

Fabrication
Aluminium / aluminum 1050A alloy can be welded using both TIG and MIG methods. The filler that is used is mostly aluminium / aluminum 4043 or 1050 alloy. Annealing of aluminium / aluminum 1050 alloy can be performed at 350°C (662°F). 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.
