Aluminum is solution treated at temperatures generally in the range of 400 to 540°C (750 to 1000°F). During solution treatment, some alloying elements are re-dissolved to produce a solute-rich solid solution. The objective of this process is to maximize the concentration of hardening elements including copper, zinc, magnesium, and (or) silicon in the solid solution. The concentration and rate of dissolution of these elements increases with temperature. Therefore, solutionizing temperatures are usually near the liquidus temperature of the alloy.
