More Detailed Introduction Of Tungsten Carbide Bush
Tungsten is known for its high melting point and durability. It’s also resistant to corrosion, which is ideal for industrial and manufacturing use. Likewise, bushings made from carbide offer an outstanding shelf life. That means you’ll spend less time switching out worn-down bushings, and more time getting the job done.
The main function of the cemented carbide bush which is a kind of tungsten carbide part, is that it can be used as the protection part of the equipment. In the process of service, tungsten carbide bushing can effectively reduce the wear between the bearing and the equipment.
In terms of stamping dies, carbide bush is widely used. Because of its wear resistance and good surface finish, it does not need to be replaced frequently, which can achieve higher utilization of equipment.
