General Information for Aluminium
Aluminium is available in a wide range of alloys, as well as multiple production processes and heat treatments.
These can be divided into two main categories of wrought alloy as listed below:
Heat Treatable or Precipitation Hardening Alloys
Heat treatable aluminium alloys consist of pure aluminium that is heated to a certain point. The alloy elements are then homogeneously added as the aluminium takes on a solid form. This heated aluminium is then quenched as the cooling atoms of the alloy elements are frozen into place.
Work Hardening Alloys
In heat-treatable alloys, ‘strain hardening’ not only enhances the strengths achieved by precipitation but also increases the reaction to precipitation hardening. Work hardening is used liberally to produce strain-hardened tempers of the non-heat-treatable alloys.
