The application of cemented carbide has played a highly important role in many fields.It is an alloy material made of a hard compound of a refractory metal and a binder metal through a powder metallurgy process.
Tungsten trioxide is one of the important materials for many metal processing and production, and it is widely used in many industries. However, when using tungsten trioxide, personal protection is also required to ensure personal safety.
Tungsten cosolvent for carbon and sulfur analyzer is a very important cosolvent, but its effect is not only cosolvent, but also includes heating, adjusting the acidity and alkalinity of the medium, stirring, catalysis, stable combustion, anti-interference, etc.
Tungsten carbide ceramic powder, this product is somewhat unfamiliar to many people, but in fact it is a very important alloy.For tungsten carbide ceramic powder, it is also called super hard alloy, which is a kind of ceramic alloy with high hardness and wear resistance.
The development history of ferroalloys has a long history. It can be said that since the emergence of industrial society, ferroalloys are an important content that cannot be ignored. For ferroalloys, from the aspects of ferroalloy smelting methods, development scale and technical equipment level, the development of the world ferroalloy industry can be roughly divided into three development periods.
Alloy powder is a very important mixture and plays an important role in many processing and production. Therefore, whether it is from the source of production, or later processing, packaging and transportation, it is necessary to ensure the procedures of each step.
Tungsten powder is the main raw material for processing powder metallurgy tungsten products and tungsten alloys. Pure tungsten powder can be made into wire, rod, tube, plate and other processed materials and certain shaped products.
The use of pigment-grade tungsten trioxide plays a very important role in people's lives. Although people do not have much contact with it in their daily lives, various products made from pigment-grade tungsten trioxide can often see.
The use of environmental protection fishing weights is a very good choice for many fishing enthusiasts. Many fishing enthusiasts like to use environmental protection fishing weights, not only because of the advantages brought by their own products, but also for the superposition of fishing results.
The market development of GB 80 ferrotungsten has a very good development prospect in my country, but from the perspective of foreign development, there is still a certain distance. Under such circumstances, the market has also proposed another form for the development of GB 80 ferrotungsten, and believes that it will be carried out by completely copying foreign technology, but in fact such an idea is not desirable and cannot be blindly followed.
