Aluminium and Aluminium Alloys

Aluminium is a light metal; its density is approximately a third of the density of steel.Pure aluminium forms a thin oxide layer when it comes into contact with oxygen which results in a mat, dull appearance.By adding alloying agents, e.g. magnesium, silicon, copper and other metals, the mechanical properties can be changed, e.g. for improving the properties for drilling, turning and milling (AW-Al Cu4PbMgMn) or increasing the strength (e.g. for AW-Al Si1MgMn).
