Brass wire is usually an extremely useful type of precipitation hardening alloys. If the brass wire after solid solution and aging treatment, its strength can reach 1250-1500 kg. So, brass wire is more suitable for a kind of solution heat treatment line of silk.
Brass wire generally solid solution treatment temperature between 780-820 ℃, on the elastic component is used as the materials, the 760-760 ℃, main is to prevent the coarse grains impact strength. Average degree shall be strictly controlled in solid solution treatment temperature + 5 ℃. Holding time can generally be calculated by 1 small / 25 mm, brass wire in the air or oxidizing atmosphere solid solution heat treatment, surface oxidation film. Is to strengthen aging after the mechanical function of the impact is not big, but will affect its cold working die service life. In order to avoid oxidation should be in a vacuum furnace or heating in the ammonia decomposition, inert gas, reducing atmosphere, can achieve the bright heat treatment effect.
