Heat Treatment

Heat Treatment of Aluminium casting / forgings is done for parts that require higher mechanical properties, higher tensile strength, different properties from the as cast / forged material or need to maintain very close tolerance during machining.  Heat treatment changes  the properties of the alloy by subjecting the casting/forging to a thermal cycle.   Heat Treatment temperature cycles are different for each aluminium alloy grade.  The heat treat temperature and soaking time determines the hardness, desired microstructure, and tensile strength for the heat-treated parts made from a particular alloy.
