Carbide die lifetime of greater than much that regarding steel or even many times



Tungsten Carbide Seal time of greater than ten times that regarding steel or perhaps lots of times, hard alloy moulds only high hardness, high strength, corrosion resistance, high temperature resistant and low expansion coefficient, are generally use cobalt tungsten Carbide.
As the market standard material YG3, YG6, YG6X YG8. YG15, YG20, YG20C, YG25 and HU20 HU222, HWN1 (non-magnetic alloy mold), etc., using native Carbide material, low pressure sintering as well as other special craft, toughness is preferable to the regular production, life will likely improve 3-5 times.
Hard alloy moulds according to use might be split into four categories:
The first category for cemented Carbide Bushings drawing die, nearly all of this sort of mould of cemented Tungsten Carbide Tube mould. Presently the main model of wire drawing die YG8, YG6, YG3, followed by the YG15, YG6X, YG3X, developed new brands, like employed in high-speed wire drawing new brand YL, and through the amount of imported wire drawing die CS05 (YLO. 5), CG20 (YL20), CG40 (YL30); K10/19 dated, ZK20 / ZK30.
The next type of mold is cold cold heading die, plastic mould, the main brands are YC20C, YG20, YG15, CT35 and YJT30 MO15.
The third form of mould is employed for magnetic material creation of non-magnetic alloy mold, including number of YSN YSN (20, 25, 30, 35, including 40) and steel bonded magnetic mold brand TMF.
The 4th class for hot-work die, this kind of alloy temporary top brands, industry should increase. Cemented Carbide mould is: cold heading die, cold punching die, drawing die, hexagonal die, screw die, etc.
