Introduction
Aluminium / aluminum is a unique metal that reacts with oxygen in the air to form a very thin layer of oxide; however this layer is dense and provides the metal excellent corrosion protection. Another plus point is that this layer is self-repairing if removed or damaged.
Aluminium / aluminum 8030 alloy is a wrought alloy. The following datasheet will provide more details about aluminium / aluminum 8030 alloy.
