Heat Treating

Solution Heat Treatment

Solution Heat Treatment is a treatment in which an aluminum alloy is heated to a suitable temperature and held at this temperature for a sufficient length of time to allow a desired constituent to enter into the solid solution, followed by rapid cooling to hold the constituent in the solution.

Precipitation (Age Hardening)

A time-temperature-dependent change in the properties of certain aluminum alloys. It is the result of precipitation from a solid solution of one or more compounds whose solubility decreases with decreasing temperature. For each alloy susceptible to aging, there is a unique range of time-temperature combinations to which it will respond.
