What do you mean by aluminum alloy T3-T8? Someone who answers me, thanks a lot
T3~T8 refers to the heat treatment process code after extrusionAs follows:T3 solid fusion heat treatment, cold processing, and then through the natural aging to the basic state of stabilityThe utility model is suitable for cold working, straightening or leveling to improve the strength after the solid fusion heat treatmentT4The natural aging is basically stable after the heat treatmentApply to solid melting heat treatment, no longer cold processing (can be short, straight and flat, but not affect mechanical performance limit) products
Aluminum alloy profile T3 refers to natural aging after solid solution treatment.Aluminum alloy profile T8 refers to solution treatment, cold work, artificial aging.
T5It is cooled by a high temperature molding process and then artificially agedThe utility model is suitable for the artificial aging product after being cooled by the high temperature forming process without being cold processed (which can be straightened and straightened without affecting the mechanical performance limit)T6The state of artificial ageing after solid heat treatmentSuitable for solid melting heat treatment, no longer cold processing (can be straightened, leveling, but does not affect the mechanical performance limit) productsT7The state of over ageing after solid heat treatmentSuitable for solid heat treatment, in order to obtain some important characteristics, in artificial aging, the strength on the aging curve crossed the peak point of the productT8 solid fusion heat treatment, after cold processing, and then the state of artificial agingSuitable for cold processing, or straightening, leveling, in order to improve the strength of products
