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.Heat treatment process for wide and thick plates 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.Process Of Preventing Deformation And Cracking Of Mold By Vacuum Heat Treatment Alloys containing the main strengthening phases CuAl and S(A1:CuMg) are naturally aged and processed.Both aging methods are available. For example, 2A11 and 2A12 alloys can achieve the best strengthening effect by using natural aging or in-process aging. vacuum-brazing-repair-method-for-cracks Which aging method is used depends on the nature and use of the alloy. Generally, deformed aluminum alloys that work at high temperatures usually use working aging, while deformed aluminum alloys that work at room temperature should use natural aging.Vacuum brazing of ceramic and metal materials
