Application of tungsten carbide cobalt powder:

Coercive force of tungsten-cobalt alloy Because the binder phase in cemented carbide is ferromagnetic material, the alloy has certain magnetic properties, and the coercive force can be used to control the structure of the alloy. It is an internal control finger for tungsten steel manufacturers. . The coercive force of WC-Co alloy is mainly related to the drilling content and its dispersion, and increases with the decrease of cobalt content. When the amount of cobalt is constant, the degree of dispersion of the cobalt phase increases as the tungsten carbide grains become finer, so that the coercive force also increases. On the contrary, the coercive force is lowered. Therefore, under the same conditions, the coercive force can be used as a parameter to indirectly measure the grain size of tungsten carbide in the alloy: in the alloy of normal structure, as the carbon content decreases, the tungsten content in the drilled phase increases. When the cobalt phase is greatly strengthened, the coercive force is increased. Therefore, the larger the cooling rate at the time of sintering, the larger the coercive force.
Since tungsten carbide has a high modulus of elasticity value, the WC-Co alloy also has a high elastic grinding amount. As the cobalt content in the alloy increases, the elastic modulus decreases; the grain size of tungsten carbide in the alloy has no significant effect on the elastic modulus. As the temperature of use increases, the modulus of elasticity of the alloy decreases.
