Aluminium Alloys

Aluminium is mostly used in form of alloys of pure aluminium in combination with other elements in order to improve the mechanical properties of the metal, especially to increase strength and corrosion resistance.

Alloy elements to achieve certain properties on the final product:

  • increases the strength
  • in combination with Mg higher strength
  • increases the mechanical properties, reduces corrosion-resistance
  • increases the mechanical properties, changes deep-drawing quality
  • high strength after cold forming
  • more strength in combination with elements like Cu, Mn, Mg
  • higher strength
  • reduces corrosion-resistance
