 The method of increasing the strength and hardness of aluminum alloys by naturally parking them at room temperature for a certain period of time is called natural aging. The method of keeping aluminum alloy products at a certain temperature higher than room temperature for a certain period of time to improve the strength and hardness of the aluminum alloy is called processing aging. Vacuum Hardening and Vacuum Tempering Heat Treatment for Metal Parts For the Al-Mg-Si 6063 alloy, natural aging proceeds very slowly. Staying for half a month, or even longer, will not achieve the best strengthening effect. The strengthening effect is 30% to 50% worse than the strengthening effect of the aging process, so the aging process is generally used. Alloys containing the main strengthening phases Mg; Si, MgZn and Al-Mg, Zn can only obtain the highest strength by aging.
