Diamond Wire Drawing Die Blanks

What is PCD Wire Drawing Dies Used for?

The diamond wire drawing dies blank is made by sintering diamond micropowder under the action of various metals (containing cobalt) catalysts using ultrahigh temperature and ultrahigh-pressure processes. During the sintering process, high-strength diamond bonds are formed between the diamond microcrystalline particles, and the diamond fine powder particles are strongly combined to form polycrystalline diamond (PCD). The diamond wire drawing dies blank manufactured by this method has high wear resistance, hardness and thermal conductivity, but also has good mechanical strength and toughness. It is suitable for drawing copper, aluminum, nickel and other non-ferrous metals, stainless steel and various alloy wire.
