What are tempers and what do those silly letters and numbers mean?
Tempers The industry method of defining how much cold work is in the material and what high temperature processes may have been used to affect the strength of the material. A or TB00 In beryllium copper this means the material is annealed; however, it is a special anneal. CuBe Alloys heats the metal to a very specific temperature and holds the metal for just the right amount of time. Then CuBe Alloys takes the metal out of the furnace and very quickly quenches the metal in a large water pit.
