Wear Resistance of Tungsten Carbide 

Tungsten carbide, also known as cemented carbide, hard alloy, or tungsten alloy, is one of the hardest tool materials in the world, only after diamond. Nowadays, people require more and more properties of tungsten carbide and apply it in their industrial works, such as tungsten carbide buttons, tungsten carbide inserts, tungsten carbide rods, and so on. Tungsten carbides are extremely hard, resistant to shock, impact, abrasive and wear, and durable and stiff. In this article, you will understand the wear resistance of tungsten carbide further.

Tungsten carbide can be made in different shapes, and the tungsten carbide button is one of the widely used tungsten carbide products, which can be used as a part of the shears. Shears will be in contact with the coal layer directly during the working. The abrasive wear of shear is highly related to the structure and hardness of the coal layer. Coal has low hardness, but other substances in the coal layer, such as quartz and pyrite, have higher hardness and are possible to cause the wear of tungsten carbide buttons.

Wear resistance is the basic function of tool material, and it is always related to the hardness of the tool material. The higher the hardness, the higher the abrasive wear resistance. The hardness of tungsten carbide is much higher than that of most materials, and so does the wear resistance. What’s more, at a high temperature of 1 000°C, coarse-grained WC hard alloys have higher hardness than ordinary hard alloys and show good red hardness.

In the coal cutting process, tungsten carbide buttons are the main parts to contact with the rock formation and coal layer, which may cause abrasive wear, adhesive wear, and sometimes erosive wear will also occur. One thing we can’t deny is that even though the tungsten carbide has high wear resistance, the wear can not be annihilated. What we can do is try to reduce the possibility of wearing as much as we can.

It is the great wear resistance of tungsten carbide that make tungsten carbides widely used in many fields, such as mining, oil, gas, military, machinery, manufacturing, aviation, and other fields. Not only tungsten carbide buttons but other products such as tungsten carbide wear parts, tungsten carbide inserts, and tungsten carbide composite rods have high wear resistance.
