Specifically, the embrittlement effect caused by oxygen in tungsten products and cemented carbide is used for the segregation of oxygen on the crystal plane. This segregation reduces the surface energy and leads to intergranular cracking.
The processing methods of tungsten powder include hydrogen reduction method and carbon reduction method, which are the early processing methods of tungsten powder.
Cemented carbide powder is an alloy material made from hard compounds of refractory metals and bonding metals through powder metallurgy.
Choosing a tungsten powder manufacturer with a good reputation actually has different opinions among different people. Regular tungsten powder manufacturers have a stable supply of raw materials, professional production equipment and scientific and reasonable process control.
With the emergence of new technologies, the development trend of the ferroalloy sales industry is more obvious. If 2016 is used as a benchmark, the market size of the ferroalloy sales industry will increase by about 2.7 times by 2025.
When the alloy powder is manufactured, there will be agglomeration phenomenon, so how to solve such a problem properly?
Ferroalloy powder is used in quarry, chemical industry, metallurgy, electric power, cement and other mechanical equipment industries. With the long-term use and aging of equipment, such as gas turbine rotor journals and blades, roll journals, and archways in steel mills, local damage occurs.
The production and processing of tungsten carbide granular products is an important work involved in many industries today. In the iron and steel industry, tungsten carbide particles are used as additives to produce other products, and these products belong to tungsten carbide particle products.
The application of tungsten powder is an important part of industrial production, especially in the steel industry, there is a great demand for the application of tungsten powder.
In today's market, with the rapid development of technologies such as 3D printing technology, porous materials, high-density powder coating and injection molding, among the application requirements of materials, the demand for spherical tungsten powder is increasing.
