machining. In the context of aluminum alloys, temper designa-tions are used to codify combinations of heat treatments. These are described in Table 1 in the section “Heat Treatment of Alumi-num-Base Alloys.” Precipitation hardening (age hardening) involves heating an alloy to a sufficiently high temperature so that enough of an

Surface Treatment Of Aluminum And Aluminum Alloys

Aluminum alloys are divided into two major categories: wrought and casting alloys. A further differentiation for each category is based primary on mechanism of property development. Many alloys respond to thermal treatment based on phase solubility. These treatments include solution heat treatment, quenching and precipitation, or age hardening.
