The pcd wire die drawing blank is a diamond fine powder sintered by ultra-high temperature and 

ultra-high pressure process under the action of various metal (cobalt-containing) catalysts. 

During the sintering process, high-strength diamond bonds are formed between the diamond 

crystallite particles, and the diamond micropowder particles are strongly bonded together to form 

polycrystalline diamond (PCD). The pcd die blanks produced by the method has high wear resistance, 

hardness and thermal conductivity, and has good mechanical strength and toughness, and is suitable 

for drawing non-ferrous metals such as copper, aluminum and nickel, stainless steel and various alloys wire.
