10% cobalt wolfram cobalt valve balls used under high temperature
Brief Introduction of Tungsten Carbide Polished balls
1.Extremely bright and smooth spherical surface finish can be achieved G25 tolerance grade.
2.Grinding with high hardness and wear resistance and low friction coefficient,
3.tungsten carbide ball can be used as wear-resistant tungsten carbide precision parts manufacturing applications on a variety of high-tech equipment and items such as pens industry, bearings, instruments, meters and other industries.
Advantange of our tungsten carbide valve balls
1.Tungsten carbide valve ball have a high wear resistance tungsten carbide materials and corrosion resistance, etc.
2.the work is mainly used in all kinds of seals, and the pellets compared to other materials such as steel ball and so has higher value and longer use lifetime.
3.Some sealing valve work environment is at very high temperatures,tungsten carbide balls are to meet its high temperature performance requirements.
