Industrial applications of cemented carbide
1. Cutting tool material
Cemented carbide adopted as the cutting tool material, is the widest application. Among the carbide tools, the tungsten cobalt carbide is suitable for the cutting of black metal, non-ferrous metals and processing of non-metallic materials, such as cast iron, cast brass, colloidal wood, etc. Cemented tungsten titanium cobalt is applied for steel and other black metals processing. In the same kind, there is more cobalt content, suitable for rough machining and less cobalt content is used for fine machining. Universal cemented carbide has a much longer service life than that of stainless steel which is difficult for processing.

2. Mould material
Cemented carbide is mainly used for cold wire drawing dies, cold punching dies, cold extrusion mode, cold heading dies and other cold stamping molds.

Under the wear-resistant working conditions which have a strong impact, the tungsten carbide wire drawing dies are required to have a good impact toughness, fracture toughness, fatigue strength, bend intensity and excellent wear resistance. Usually, among grades of high cobalt and medium, crude granules, the YG15C is commonly adopted.

In general, the relationship between the carbide wear resistance and carbide toughness is contradictory. The increase in wear resistance will result in a decrease in toughness and the increase in toughness will inevitably lead to a decrease in wear resistance. Therefore, when choosing a cemented grade, it is necessary to meet specific usage requirements based on the processing objects and processing conditions.

If the selected grade is easy to occur early cracks, it is advisable to use a grade with high toughness. if the selected grades is easily damaged due to the early wear, it is appropriate to choose a grade with a higher hardness and better wear resistance. The following grades of YG15C, YG18C, YG20C, YL60, YG22C, YG25C have a gradual decrease in hardness and wear resistance and gradually improving toughness.

3. Measuring tools and wear parts
The cemented carbide is adopted in the wear surface inlay and parts of the measuring tools, precision bearing manufactured by grinding machine and the wear parts such as guide bar, lathe center.
