Tungsten-cobalt alloy has some special advantages among cemented carbide materials. It is a typical cemented carbide with high hardness and strength as well as good toughness. This makes tungsten-cobalt alloys very popular in the manufacture of cutting tools, wear-resistant parts and components used in high-temperature environments.
The main components of tungsten-cobalt alloy are tungsten carbide and cobalt. The content of tungsten carbide is usually more than 85%, and the content of cobalt is more than 10%. This alloy has a range of excellent properties, including high flexural strength, compressive strength, impact toughness, elastic modulus and a small coefficient of thermal expansion. These properties make tungsten-cobalt alloy the most widely used type of cemented carbide.
In addition, the appearance of tungsten-cobalt alloy coating is similar to that of chromium coating, and has good decorative properties and corrosion resistance. At the same time, the dispersion and coverage capabilities of the plating solution are also very good, which can form a uniform and dense film layer on the metal surface, thus improving the corrosion resistance and wear resistance of metal products.
In addition, tungsten-cobalt alloy also has good heat resistance and cold resistance, and can maintain its high strength and hardness at high temperatures up to 1000°C without obvious aging deformation. This makes tungsten-cobalt alloys have broad application prospects in the manufacturing of parts used in high-temperature environments.
In short, tungsten-cobalt alloy, as a typical cemented carbide material, has high hardness, high strength, good toughness and excellent corrosion resistance, heat resistance and wear resistance. Therefore, it is widely used in manufacturing cutting tools and wear resistance. It has broad application prospects in parts and components used in high temperature environments.
