The aluminum alloy profile after extrusion molding needs to be heat treated to improve its mechanical properties and corrosion resistance. Common heat treatment methods include solution treatment, aging treatment, etc. Solution treatment is to heat the profile to a certain temperature and then cool it quickly to make the alloy elements evenly distributed in the aluminum matrix. Aging treatment is to keep the temperature at a low temperature for a long time to precipitate the alloy elements, form a fine precipitation phase, and enhance the strength and hardness of the profile.
