The wire drawing die blanks produced by our company are very pure polycrystalline diamond. No other materials were added and they are of high hardness and good abrasion resistance. They also have the advantages of the poly-and the mono-crystallite, and they can be widely used in wire drawing of stainless steel, tungsten, molybdenum, copper, aluminum and many other alloy materials.The wire drawing die blanks produced by our company are the ideal substitute for the natural and the poly-crystallite .
