Tungsten carbide (WC) is a compound composed of refractory metal tungsten and nonmetallic carbon. It has the characteristics of high density, high melting point, high strength, high hardness, high-temperature resistance, corrosion resistance, wear resistance, and good electrical and thermal conductivity, so it is the ideal cemented carbide tool material.

However, due to the problems of high brittleness and poor toughness of simple WC powder, it is often necessary to add an appropriate amount of binders such as cobalt (Co), nickel (Ni), chromium (Cr), molybdenum (Mo), titanium (Ti), copper (Cu) and other elements in making cemented carbide tools with high comprehensive performance. 

Specifically, cemented carbide with WC powder as the hard phase and Co as the bonding phase is more suitable for cutting tools. Because of its good thermal conductivity, it is conducive to the loss of cutting heat from the tip, reduces the temperature of the tip, and avoids the overheating and softening of the tip; Due to its high bending strength and impact toughness, it can effectively reduce the probability of edge breakage in cutting. Because of its excellent cutting resistance (far more than high-speed steel), it can grind out a sharp edge. 

Cemented carbide with WC powder as the hard phase and Ni as the bonding phase is more suitable for corrosion-resistant parts. Its corrosion resistance is stronger than that of tungsten cobalt carbide tools, so it is suitable for application in a variety of corrosive media environments. In addition, WC-Ni cemented carbide seals are also suitable for application in low temperature, high temperature, vacuum, and high pressure. 

Cemented carbide, composed of WC, TiC, and Co, has high hardness, good heat resistance, high compressive strength, good oxidation resistance, poor thermal conductivity, and other characteristics, suitable for processing steel. 

The physical properties of cemented carbide vary with the ratio of raw materials. If the carbide surface is sprayed with a layer or layers of carbide, carbide, and other refractory hard compounds, then the alloy will be further compatible with high wear resistance and high toughness, so it is more suitable for high-speed cutting.
