Why is tungsten carbide cold heading die performance better?
In the standard parts industry, tungsten carbide cold heading dies to need to under great unit pressure in cold upsetting deformation process, when a large degree of deformation and material hardness, units of pressure up to 2000MPa more.
At the same time the metal flow intense, thus requiring tungsten carbide cold heading dies to have high strength, high hardness, and good fatigue resistance, in order to ensure the cold heading dies under high pressure without breaking, deformation, and wear resistance. Tungsten carbide cold heading dies raw material is produced by powder metallurgy composite materials, which have high hardness, wear resistance, life is several times and several hundred times than ordinary cold heading die.
With carbide manufacturing standard tungsten carbide cold heading die, not only have high dimensional accuracy of parts but also greatly improve the life of the cold heading die, can create good economic and social benefits.
