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, carbide materials are often used in industrial manufacturing fields such as metal processing tools and molds.

Part One: What is carbide materials？
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.Commonly used cemented carbides are divided into three categories according to their composition and performance characteristics: tungsten-cobalt, tungsten-titanium-cobalt, and tungsten-titanium-cobalt (niobium). The most widely used in production are tungsten-cobalt and tungsten-titanium-cobalt cemented carbide.
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.
Part Two: What is the application of carbide materials？
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 CNC drilling tools, CNC milling machines, and CNC 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 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 CNC machining. 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.
Part Three：What is the difficulty in carbide part machining？
The processing of cemented carbide is not easy and there are many difficulties. First of all, due to its high hardness and brittleness, traditional processing methods are often difficult to meet the requirements and can easily lead to defects such as cracks and deformation in the product. Secondly, cemented carbide is used in high-end fields, so the requirements for machining accuracy are very high. During the processing process, many factors must be taken into consideration, such as cutting tools, fixtures, process parameters, etc., to ensure product accuracy. Finally, the surface quality requirements of cemented carbide are also very high. Due to its greater brittleness, the surface is easily damaged, so special processing methods and equipment (such as ultra-precision grinders, electrolytic polishers, etc.) need to be used to ensure surface quality.
In short, cemented carbide is increasingly used in CNC machining, playing a key role in improving production efficiency and product quality in machinery, electronics, chemicals, aerospace and other industries.GPM has advanced processing equipment and technology that can process supercarbide parts efficiently and accurately. A strict quality control system during the processing process ensures that each part meets customer requirements and standards.
