在铝材生产中,金属或合金的状态占着很重要的作用。所谓状态(temper)就是金属或合金通过某些生产工序(例如压力加工、热处理)产生了特有的物理和力学性能之后所给予的命名,同时每一种状态都用一定的英文字母或数字与英文字母的组合来表示,如“O”表示退火状态,“H”表示加工硬化状态, “T4”表示固溶热处理后自然时效至基本稳定的状态,“T6”表示固熔热处理后进行了人工时效的状态,等等。 In the aluminum production, the state of the metal or alloy plays a very important role. The so-called temper is the name given after a metal or alloy has had its own unique physical and mechanical properties through certain manufacturing processes (eg, press working, heat treatment), each of which is identified in English letters or numbers “T4” stands for the natural aging after solution heat treatment to the basic stable state, “T6” indicates that the annealing state, “H” indicates the work hardening state, “T4” Solid-state heat treatment after the artificial aging state, and so on.
