SFD 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 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 3micron, 5micron, 10micron, 25micron and 50micron 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.

CD die blanks contains catalyst metal and is thermally stable to 650 degrees Celsius, and to be mounted at temperature not exceeding 650 degrees Celsius. CD blank is electrically and can be drilled and shaped by EDM, laser and ultrasonic etc.
