What are the specific steps for strengthening aluminum alloy profiles?

• Solid solution treatment: the aluminum alloy is heated to a single-phase alpha solid solution state, and then rapidly cooled after heat preservation to obtain a supersaturated alpha solid solution.

Aging treatment: The obtained supersaturated α solid solution may be subjected to aging treatment, and may be left at room temperature for a long time (natural aging), or may be subjected to heat preservation at a temperature lower than the saturated solid solubility line (artificial aging). During the aging process, the supersaturated α solid solution precipitates fine and dispersed second phase particles, thereby increasing the strength of the alloy.

These steps work together to achieve the strengthening treatment of aluminum alloy profiles.
