Publisher:tungsten carbide powder
Tungsten carbide powder has high purity, uniform particle size and good dispersion. It is an important raw material for the production of cemented carbide. Tungsten carbide powder can make cemented carbide have many more excellent characteristics, insoluble in cold water, strong acid resistance, high hardness, elastic mold large. In addition to high hardness, tungsten carbide powder also has the characteristics of wear resistance, corrosion resistance and high temperature resistance. The main uses of tungsten carbide powder are:
1. As a raw material for the production of cemented carbide. However, depending on the application of the alloy, the particle size of the tungsten carbide used is also different.
2. As a spraying material, it has the characteristics of high density, high bonding strength, high hardness and low porosity.
3. Preparation of silver tungsten carbide electrical contacts. Electrical contacts are important components of high-voltage circuit breakers, switch cabinets, disconnectors, and grounding switches.
Qingdao Hesiway Industrial Co., Ltd. is a foreign trade company established by Qingdao Juxinyuan Industry and Trade Co., Ltd. to better serve foreign customers. The company specializes in the production of tungsten series products, and the particle size can be customized according to customer requirements. If you want to know more about the use of tungsten carbide powder, welcome to consult us.

The processing of ferroalloy powder can be carried out through the following steps:Raw material preparation: Select appropriate ferroalloy powder, such as pure iron, low carbon steel, high carbon steel, etc., and prepare processing equipment, such as hydraulic press, die, grinding equipment, etc.
The advantages of resin tungsten powder mainly include:High density: Resin tungsten powder has a high density, which helps to improve product quality and performance.Good plasticity: Resin tungsten powder has good plasticity and can be processed into products of various shapes and specifications.
The molding process of alloy powder generally includes injection molding and compression molding.The press molding process requires the use of hydraulic press equipment for pressing.
High-purity tungsten carbide particles have the following performance characteristics:High hardness: The hardness of high-purity tungsten carbide particles is very high, reaching above HRA93.0, which makes it have excellent wear resistance and impact resistance.
The applications of high-purity tungsten powder mainly include the following fields:Cemented carbide preparation: High-purity tungsten powder is an important raw material for the production of cemented carbide and can be used to manufacture carbide tools such as turning tools, milling cutters, drill bits and molds.
Coarse-grained tungsten carbide is used to produce cemented carbide and can also be used as an additive for aerospace cables.Tungsten carbide is a metal carbide powder and an alloy powder.
The functions of tungsten trioxide are as follows:Petrochemical field. Tungsten trioxide can be used as a catalyst. When used as a catalyst, it not only has high catalytic activity and long service life, but more importantly, it is environmentally friendly, non-toxic and pollution-free.
Tungsten carbide particles are used in many industries due to its superior hardness properties compared to tool steels and superior toughness compared to technical ceramics.
As an important intermediate product of transition metal tungsten, tungsten powder has strong reducing properties and is often used to produce tungsten products such as tungsten oxide, tungstate, tungsten carbide, tungsten rods, and tungsten strips.
