This article summarizes a typical solution and aging heat treatments of 2xxx (Al-Cu), 6xxx (Al-Mg-Si), and 7xxx (Al-Zn-Mg) wrought alloys. It discusses the general aging characteristics and the effects of reheating of aluminum alloys. Typical examples of hardness and conductivity values for various aluminum alloy tempers are listed in a table. The article also describes the age hardening of Al-Cu (Mg) alloys, Al-Mg-Si alloys, and Zn-Mg-(Cu) aluminum alloys.
