The performance of tungsten carbide mold parts material

     Hard alloy die material has high hardness and wear resistance,especially at higher temperatures, its hardness is still high. Such as 600 C, the hardness is higher than the normal temperature of high speed steel. At 1000 C, the hardness is higher than that of carbon steel.
     Tungsten carbide mold parts material has very high elastic modulus, which is usually (4~7) *10^5MPa, the rigidity is good at room temperature.
     With a high compressive strength, up to yizedbzt06 6000MPa.
     With the relatively stable chemical properties, some varieties of hard alloy to acid resistance, alkali resistance, even at high temperatures also won't have obvious oxidation.

     Low thermal expansion coefficient.
     The thermal conductivity and electrical conductivity are similar to iron or iron alloy.
     Steel bonded hard alloy also has mechanical properties, heat treatment, forging performance.
     The steel bonded tungsten carbide mold parts also has a low coefficient of friction.
     Because of these properties, tungsten carbide mold parts in the mold industry has a good use effect.
