With the property of high wear resistance, good polishing performance, low friction coefficient, etc ., cemented carbide drawing die has been a substitute of steel mold which is used to stretching steel and non-ferrous metal.

In Shanghai Material Factory, the Cobalt content is declined to 6 % and a few TaC are added into cemented carbide drawing dies in the sintering process so that the production volume is two times of that of general grade when stretching A3 steel, YIF steel, copper, etc.

Currently, WC-Co cemented carbide is widely used in China, Japan, Sweden, Italy, etc . In some other counties, rare metal carbides ( such as TiC, TaC, NBC, etc . ) are added into cemented carbide drawing dies and its manufacturing process is also certainly different.

When sintered or applied using thermal spray methods, the tough outer layers chemically bond, forming a metal matrix in the sintered article or deposited coating, This hybrid material combines the high strength, heat resistance, and toughness of cemented carbides with the chemical and abrasion wear resistance of the harder core particles.
