The precision alloy produced by our factory mainly applies to electrical component, hard glass, soft glass, glassy-closure alloy of ceramic match sealing, soft magnetic alloy, elastic alloy, including iron, nickel, cobalt alloy 4J29, iron-chromium alloy 4J28 , iron-nickel alloy 1J36, 1J50, 1J79, 1J80, 3J9, 4J42, 4J50 etc.. The product specifications include silk, belt, pipe, sheet and rod materials. The smelting process of the alloy is undertaken in the non-vacuum induction furnace and vacuum induction furnace, the other smelting methods which can meet the requirements also can be used. If the demand side has some special requirements to the smelting method, the requirements should be specified in the contract.
