Polycrystalline Dimond 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 thermal conductivity, but also posses high mechanical strength and tenacity. They are suitable for high-speed drawing of non ferrous wires such as bronze, aluminium, and nickel and that of stainless steel and other alloy wires.
