About Aluminum alloy Heat Treatment

Aluminum alloy heat treatment is to select a certain heat treatment specification, control the heating rate to a certain temperature and keep the temperature for a certain time to cool at a certain speed, change the structure of its alloy, its main purpose is to improve the mechanical properties of the alloy, enhance the corrosion resistance, improve the processing performance, and obtain the dimensional stability.

For steel with high carbon content, high hardness and low plasticity are obtained immediately after quenching. However, for aluminum alloy, the strength and hardness do not rise immediately after quenching; instead, the plasticity does not decline but rises. However, when the hardened alloy is placed for a period of time (such as 4 to 6 days and nights), its strength and hardness will be significantly improved, while its plasticity will be significantly reduced. The phenomenon that the strength and hardness of aluminum alloy increase significantly with time after quenching is called ageing. Aging can occur at room temperature, according to the natural aging, can also be higher than the room temperature at some stage in the temperature range (100 ~ 200 ℃), called artificial aging.
