Material properties of tungsten carbide
The tungsten carbide is an alloy which has the main component of powders including tungsten carbide, titanium carbide and metal powder such as cobalt, nickel, etc, as an adhesive, obtained through the powder metallurgical method. It is mainly used to make high-speed cutting tools and hard, tough material cutting edges, and high wear parts for fabrication of cold dies, measuring tools.

1.Wear resistance
The wear resistance of the tungsten carbide is its most important feature. In practical applications, carbides are 20-100 times longer than some wear-resistant steel alloys.

2.Bending resistance
The sintered carbide has a high elastic modulus and the smallest bend is obtained when subjected to bending force.

3.Corrosion resistance
It is usually used in many chemical and corrosive environments because carbides are typically chemically inert.

4.Torsional strength
The amount of torsion is two times than the high-speed steel and the carbide is the preferred material for high-speed operation applications.

5.Compressive strength
Some grades of cobalt carbide and cobalt have perfect performance under ultra-high pressure and is very successful in pressure applications of up to 7 million kPa.

6.Toughness
Cemented carbide grades with high binder content have excellent impact resistance.

7.Low temperature wear resistance
Even at an extremely low temperature, the carbide remains good to wear resistance and provides relatively low friction coefficients without using a lubricant.
