PCD Die Blanks are Polycrystalline Diamond (PCD) products made under ultra-high temperature and ultra-high pressure, during which process diamond powders are sintered together with strong grain-to-grain bonding under the functioning of a few metal catalysts containing Cobalt. These PCD products not only have high wear resistance, hardness and good thermal conductivity, but also possess high mechanical strength and tenacity. They are suitable for high-speed drawing of nonferrous wires such as bronze, aluminum, nickel and that of stainless steel and other alloy wires.
