Superfine tungsten carbide powder has good compatibility, which can improve the sharpness of the tool, and it can be prepared by one-step reduction carbonization method. Characteristic Superfine tungsten carbide powder has good compatibility with iron, copper, cobalt and nickel, which can increase the wear resistance of the tire body, reduce the variation of the matrix, and improve the sharpness of the tool. Preparation Compared with the traditional process, a one-step reduction carbonization method is used to prepare superfine tungsten carbide…

Fine particle tungsten carbide powder has smaller particle size, high specific surface area and good catalytic activity. It can replace precious metal as catalyst, but also can be used as raw material for the production of tungsten carbide. Particle The main influencing factors of fine particle tungsten carbide powder are the particle size and the composition of the tungsten powder. Due to the carbonization process is mainly achieved by the reaction of the surface of the tungsten powder particles with…

Nanometer tungsten carbide powder is a kind of tungsten carbide powder with a particle size <100nm, which has the properties of the abnormal tungsten carbide powder. It can make the tungsten carbide with more excellent properties. Particle When the particle size of the tungsten carbide powder varies greatly, the characteristic of the powder is obviously different. Especially when the particle size reaches the nanometer level, it often shows the abnormal performance of the conventional tungsten carbide powder. Applications Nanometer tungsten…

Ultrafine tungsten carbide powder is tungsten carbide powder with particle size ≤0.5μm. It is the basic raw material for the production of ultrafine-grained tungsten carbide. It should be sealed in vacuum and cannot be stored for more than 8 months. Particle The particle size of the ultrafine tungsten carbide powder can be measured by using the microscope (SEM, TEM), the laser particle size method, the X-ray line width method and the specific surface area method. The combination of several measurement…

The chemical formula of tungsten carbide powder is WC. It is a good electric conductor with stable chemical properties. It is suitable for machining at high temperature and is the main raw material for the production of cemented Carbide. Characteristic Tungsten carbide powder is a black hexagonal crystal, with metallic luster, similar hardness to diamond, good conductor for electricity and heat. Melting point is 2870 ℃, the boiling point is 6000 ℃, the relative density is 15.63 (18 ℃). The…

Native tungsten carbide powder refers to WC prepared from native tungsten powder and carbon, which is the so called tungsten carbide powder. A relatively product of native tungsten carbide powder is the reproduced tungsten carbide powder, which refers to WC prepared from waste hard alloy, waste tungsten powder or other recycling material. Native tungsten carbide powder (WC) is the main raw material for the production of cemented carbide, black hexagonal crystals with metallic luster, which has the hardness closes to…

Nickel based tungsten carbide powder mainly refers to tungsten carbide powder (WC) on the basis of self-fluxing nickel-based alloy to enhance its hardness and wear-resistant. The main products of self-fluxing nickel-based alloy powder are nickel-chromium boron-silicon and nickel-boron-silicon alloy, which have overall performance of low melting point, good self-fluxing, excellent wear, corrosion and heat resistance and anti-oxidation, to be the most widely and earliest used self-fluxing alloys. Nickel based tungsten carbide powder can be divided into two types of mechanical…
