China SPUB63B wholesale lathe round tungsten carbide turning inserts Supplier, Factory

Tungsten carbide is a compound composed of tungsten and carbon, with a molecular formula of WC and a molecular weight of 195.85. It is a black hexagonal crystal with metallic luster and hardness similar to that of diamond. It is a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, but easily soluble in a mixed acid of nitric acid and hydrofluoric acid. Pure tungsten carbide is fragile, and if a small amount of titanium, cobalt and other metals are added, the brittleness can be reduced. Tungsten carbide used as a steel cutting tool is often added with titanium carbide, tantalum carbide or their mixture to improve the anti-knock ability. Tungsten carbide is chemically stable. Tungsten carbide powder is used in cemented carbide production materials.

Tungsten steel blades are made of tungsten steel. Tungsten steel is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy.

Tungsten steel has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500°C. It still has a high hardness at 1000°C.

Plastic mechanical blades have a wide range of varieties and complete specifications. They are made of high-quality steel and have good sharpness and wear resistance.
