Subultrafine tungsten carbide powder refers to tungsten carbide powder with a particle size of 0.1~0.3μm. It is a basic raw material for the production of ultra-fine-grained tungsten carbide and can be prepared by phase transfer synthesis. Application Subultrafine tungsten carbide powder is the basic raw material for the production of ultra-fine grain tungsten carbide. With the addition of suitable binders and grain growth inhibitors, it can produce high hardness, high wear resistance and high toughness. The quality of the alloy…

Superfine spherical tungsten carbide powder has spherical appearance, good fluidity, good abrasion resistance, high hardness, etc. It can be used as a high-tech material for thermal spraying, and is generally prepared by ultra-high temperature melting gas atomization. Characteristic Compared with ordinary multi-angle tungsten carbide powder, superfine spherical tungsten carbide powder has two remarkable features: First, the appearance of spherical tungsten powder, powder mobility, surface quality after coating the workpiece is high; Second, it has the fine internal grain of the…

Super fine tungsten carbide powder refers to tungsten carbide powder with a particle size of less than 0.4μm. It has good uniformity, and has the advantages of the most balanced hardness, strength, and toughness. It can be used directly as a drilling tool and durable wear-resistant part. Characteristic Super fine tungsten carbide powder has good uniformity, easy control of grain growth, low sintering temperature, low production costs, and the most balanced hardness, strength, toughness and other advantages. Application Super fine…

Super coarse tungsten carbide powder is tungsten carbide powder with particularly coarse grain size, sieve size ≥40 mesh and iron content about 0.2%. It is the raw material for producing hard surface materials and tungsten carbide. It can be prepared by the aluminothermic reduction carbide method. Application Super coarse tungsten carbide powder has a very coarse grain and is an excellent raw material for hard surface materials. However, it is used for the manufacture of hard alloys, and special processing…

Coarse tungsten carbide powder has a relatively coarse particle size and is a raw material for preparing a heterogeneous tungsten-cobalt tungsten carbide. The tungsten carbide has the advantages of high strength, high hardness, and excellent impact toughness. Application The coarse tungsten carbide powder is ball-milled for a short period and then subjected to gas classification. The tungsten carbide powder of each grain size is obtained, and then wet milled according to the coarse and fine particles and the cobalt powder.…
