CVD diamonds for wire drawing die
The CVD diamonds for wire drawing die are normally hexangular shape, with good abrasion resistance, high hardness (8000~10000Kg/mm2) and high thermal stability (~1200˚C protected by Argon), can be widely used in wire drawing of stainless steel, tungsten, molybdenum, copper, aluminum and many other alloy materials.
