Introduction
Aluminium/aluminum was first commercially used on a large scale to manufacture cookware. It is widely used in various sectors such as marine, automobile, and building, as it is easy to fabricate, provides uniform quality, and is cost-effective.
Aluminium/aluminum is commonly alloyed with magnesium, copper, manganese, silicon and zinc. Aluminium / aluminum 1180 alloy is a wrought alloy type with good corrosion resistance.
The following datasheet will provide more details about aluminium / aluminum 1180 alloy.
