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 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 351025 and 50 micron 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 blank contains catalyst metal and is thermally stable to 650 degrees, and to be mounted at temperature not exceeding 650 degrees. CD blank is electrically conductive and can be drilled and shaped by EDM, laser and ultrasonic etc.

TSD die blank is thermally stable up to 1000 degrees in an inert or reducing atmosphere, and can be mounted at high temperature with high strength metal setting powders. TSD is not electrically conductive and can be drilled and shaped by ultrasonic and laser etc, EDM not recommended. TSD die blank is recommended for high temperature tungsten and molybdenum wire drawing.
