Superhard Alloys: Wonder Materials for Industrial Manufacturing

• Hits :

Carbide is a very hard metal, second only to diamond in hardness and much harder than iron and stainless steel. At the same time, it weighs the same as gold and about twice as heavy as iron. In addition, it has excellent strength and elasticity, can maintain hardness at high temperatures, and is not easy to wear. Therefore, superhard alloys are often used in industrial manufacturing fields such as metal processing tools and molds.

Cemented carbide is made of tungsten carbide and cobalt. Tungsten carbide is a material with a high melting point. It needs to be ground into powder and then manufactured by high-temperature combustion and solidification, and cobalt is added as a binding material. Tungsten comes mainly from China, Russia and South Korea, while cobalt comes from Finland, Canada, Australia and Congo. Therefore, making superhard alloys requires global cooperation to apply this wonder material to a variety of different fields.

In order to make super hard alloy, it is necessary to grind tungsten carbide and cobalt into fine powder, and burn and solidify at high temperature (1300°C to 1500°C) to solidify the material. Cobalt is added as a bonding material to help the tungsten carbide particles stick to each other. The result is a highly durable metal with a melting point of 2900°C, making it resistant to high temperatures and well suited for high-temperature applications.

Cemented carbide has a wide range of applications. In the field of industrial manufacturing, it is widely used in the manufacture of cutting tools for metal processing such as drilling tools, milling machines, and lathes. In addition, it can be used to make molds for aluminum cans such as canned coffee and beverages, powder molding molds for automotive engine parts (sintered parts), and molds for electronic components such as mobile phones. In addition, superhard alloys can also be used to smash hard rocks such as shield tunnels, and tools to cut the surface of asphalt roads. In the field of infrastructure, cemented carbide can exert its excellent characteristics and contribute to the construction of public utilities.

In short, super hard alloy is a kind of amazing material with very high hardness and strength. In terms of production and processing, the importance of super hard alloy is self-evident. Due to its excellent hardness and strength, superhard alloys are widely used in machining equipment such as metal cutting tools, drilling tools, milling machines and lathes. In addition, it can be used to make aluminum can molds for canned coffee and beverages, powder molding molds for automotive engine parts (sintered parts), and molds for electronic components such as mobile phones, etc.

However, superhard alloys are not limited to the field of metal processing and manufacturing. It can also be used for the crushing of hard rock, such as the construction of shield tunnels, and the cutting of asphalt roads and other fields. In addition, due to its excellent characteristics, superhard alloys can also be widely used in other fields. For example, surgical instruments used in the medical field, bullets and warheads in the military field, engine components and aircraft turbine blades in the aerospace field, etc.

In addition to the application in the industry, super hard alloys also play a role in the field of scientific research. For example, it can be used to make diffraction rods in X-ray and optical research, and as a catalyst in the study of chemical reactions.

In short, the wide application of cemented carbide makes it play an important role in many fields such as industry, manufacturing, infrastructure construction and scientific research. Its excellent performance not only improves people's daily life, but also makes great contributions to the progress and development of human society.
