Why tungsten carbide becomes the core raw material of cemented carbide

Tungsten carbide, with the chemical formula WC, is a compound synthesized by tungsten (W) and carbon (C) through a specific process. It has a series of outstanding properties that make it stand out.

In terms of hardness, the Mohs hardness of tungsten carbide is as high as about 9, second only to diamond. This super hardness gives it a unique advantage in the field of cutting. When used to manufacture tools such as BTA drills, tungsten carbide can easily cut into super-hard processing materials such as hardened steel and titanium alloys, ensuring efficient processing and greatly improving production efficiency.

In terms of wear resistance, tungsten carbide can be called the "king of wear resistance". In long-term friction and cutting operations, its own loss is minimal, which means that the cutting edge of cemented carbide drills based on tungsten carbide can remain sharp for a long time, effectively reducing the number of frequent tool changes and reducing production costs, while stably maintaining high-precision processing and ensuring product quality.

Furthermore, tungsten carbide has good high-temperature stability. In the high-temperature environment generated by high-speed cutting, it can still maintain its own physical and chemical properties, without softening or oxidation, laying a solid foundation for the continuous and stable operation of tools such as drill bits under high-temperature and high-speed conditions.

In summary, tungsten carbide has become an irreplaceable core raw material for cemented carbide with its high hardness, high wear resistance and excellent high-temperature stability. It supports high-performance cutting tools such as BTA drill bits to continuously break through processing limits, meet the increasingly stringent processing needs of high-end fields such as aerospace, automobile manufacturing, and energy, and promote modern manufacturing to move forward in a higher and more sophisticated direction, injecting strong momentum into industrial development.
