I. What is tungsten carbide?
Tungsten carbide is a material, which means W+C A superior synthetic material composed of equal parts tungsten and carbon atoms is commonly referred to as tungsten carbide, or simply “carbide.” In its raw form, it appears as a dark gray powder; after sintering and the addition of binders such as cobalt, it is transformed into the hard alloys we use every day. Lizhou Hard Alloy’s tungsten carbide products are crafted by leveraging tungsten carbide as the core ingredient, combined with a premium, proprietary formulation, to achieve an optimal balance of high hardness, exceptional wear resistance, and outstanding high-temperature performance.
II. Melting Point of Tungsten Carbide
2785-2830 ℃ is the melting range of tungsten carbide.
When the temperature exceeds 2000 At ℃, tungsten’s performance is invariably superior to that of other refractory metals, with variations depending on the phase; the stable phase Restroom The melting point is approximately 2870 ℃, during the manufacturing process, Lizhou Cemented Carbide precisely leverages the high melting point of tungsten carbide to, 2000 Sintering and forming are carried out in high-temperature furnaces above ℃ to ensure material densification and stable performance, preventing softening and deformation under high-temperature service conditions. Tungsten is further protected by a coating to prevent oxidation; when extreme-condition durability is required, no material is more suitable than tungsten.
III. Why Should We Pay Attention to the Melting Point of Tungsten Carbide?
The melting point directly determines how high a temperature a material can withstand, whether it will soften, and whether it will collapse during manufacturing. So why should we pay attention to the melting point of tungsten carbide? We can understand this by considering the following points.
- Only by remaining unmelted at high temperatures can tools, dies, and wear-resistant components be ensured to neither deform nor fracture.
- Its high melting point confers superior high-temperature strength, enabling equipment to operate reliably over the long term in high-temperature environments such as hot working, welding, mining drilling, and metallurgy.
- The higher the melting point, the better the thermal stability, the longer the service life, and the lower the downtime and replacement costs.
The reason why Lizhou’s hard-alloy products can operate reliably under harsh working conditions lies in tungsten carbide. 2870 A high melting point of ℃ serves as the base, ensuring that the material remains robust even in high-temperature environments—this is a critical issue in the cemented carbide industry and precisely why we must pay close attention to the melting point of tungsten carbide.
IV. Properties and Applications of Tungsten Carbide
1. Properties of Tungsten Carbide
High hardness: 2000-2700HV
Melting point: exceeds 2000 degrees Celsius
Chemical resistance: Good
2. Applications of Tungsten Carbide
Widely used in cutting tools, relying on 2870 ℃ high melting point + Ultra-high hardness + High wear resistance—tungsten carbide is used in virtually all heavy industries. For example:
Cutting tools or machining: Used for cemented carbide tools, turning inserts, milling inserts, and drills; maintains hardness at high cutting temperatures without softening.
Mining applications: require drill bits, wear-resistant sleeves, and impact- and high-temperature-resistant components.
Steel Industry: Requires the Use of Cemented Carbide Rod Products

As evident, tungsten carbide boasts a melting point far exceeding that of conventional metals, making it the ideal choice for high-temperature, wear-resistant applications. Lizhou Cemented Carbide leverages high-purity tungsten carbide as its raw material to fully capitalize on this thermal advantage, resulting in more stable product performance.
VI. Common Issues with Tungsten Carbide
Q1 : Tungsten carbide has a lower melting point than pure tungsten—so why is it more commonly used?
A : Pure tungsten is more heat-resistant but relatively soft and less wear-resistant, whereas tungsten carbide has a hardness close to that of diamond. 2870 ℃ already meets the vast majority of industrial high-temperature requirements and offers superior overall performance.
Q2: Will LIZHOU carbides melt at high temperatures?
A : Industrial operating temperatures are generally much lower than 2870 °C—it only generates heat and does not melt, so you can use it with confidence.
Q3 : Can the melting point of tungsten carbide be increased?
A : The melting point can be raised by adding pure tungsten, but the base melting point remains at Restroom for 2780 °C as the core.
