The fine spherical tungsten powder is prepared by a plasma method and has the characteristics of good fluidity, good quality, high purity, uniform particle size distribution. It is widely used in thermal spraying, porous materials, and powder metallurgy industries. Applications Porous tungsten prepared by fine spherical tungsten powder has more uniform voids, and is gradually replacing conventional tungsten powder for making porous tungsten parts such as cathodes for high-power pulsed microwave tubes, tungsten-tungsten cathodes for electron tubes, and molten Zn.…

Fine crystalline tungsten carbide powder has stable chemical properties, and hardness is similar to that of diamond, which is a good conductor of electricity and heat. It is wear-resistant, corrosion-resistant, and high-temperature resistant. It is the main raw material for producing fine-grained carbide. Applications Fine-grain tungsten carbide powder is the main raw material for producing fine-grained hard alloys. Ultrafine grained tungsten carbide is tungsten carbide with a grain size of tungsten carbide less than 1μm. It has higher hardness, strength,…

Micron tungsten carbide cobalt composite powder has uniform element distribution, fine powder particle size, narrow particle size distribution, etc. The average particle size of the powder is 50~150nm. It is widely used in the manufacture of superfine/nanocrystalline tungsten carbide tools and surface strengthening materials. Properties The physical properties of micron tungsten carbide cobalt composite powder are very different from those of conventional powders. The non-metallic tungsten carbide phase and metal cobalt phase constitute a composite structure, not a simple mixture;…

It has excellent wear resistance and can be used as an abrasion resistant coating material and as a raw material for various cutting tools. The nano tungsten carbide cobalt composite powder has excellent effects as an abrasion-resistant…

Cobalt tungsten carbide composite powder has good wear resistance, high temperature resistance and corrosion resistance, which is a coating material with excellent wear resistance at low and middle temperatures. Preparation Cobalt and tungsten carbide have good wettability. By using good high-temperature properties of cobalt, toughness, and good combination with other metals, cobalt and tungsten carbide are combined to prepare cobalt tungsten carbide composite powder, which becomes a coating material with excellent abrasion resistance at moderate to low temperatures. Applications Cobalt…
