SIFANG diamond die blanks are polycrystalline diamond (PCD) products produced by advanced high temperature and ultra-high pressure in the presence of a solvent/catalyst metal. High degree of diamond-to-diamond assure them combine the hardness, abrasion resistance and high thermal conductivity of natural diamond with a toughness approaching that of tungsten carbide. They are better choice for high precision and long life wire drawing dies.

There are 3?#12289;5?#12289;10?#12289;25 and 50 grain sizes available. Two types of blanks can be supplied: one is self-supported and comes with a round or hexagonal shape, while the other is supported by tungsten carbide and can hence withstands greater drawing forces. CD die blanks can be used for stainless steel, copper, aluminum, nickel and their alloys etc.
