Tungsten Carbide Valve Ball

Tungsten carbide valve ball WC is a refractory metal alloy or a Ni and Co cemented metal constituted by the high temperature sintering at room temperature, rigidity, and no significant plastic deformation, and smaller thermal expansion coefficient, good dimensional stability of the product, precision high. Therefore, carbide valve ball is widely used in many military and civilian high-tech field ball rolling element bearing industry, fluid seal rotating ball, valve core, oil extraction machine-way valve, valve seat and so on. Chinatungsten Online production of carbide valve ball sold to various regions of the world, according to the specific needs of the user, to design, produce different composition, performance and use requirements of tungsten carbide balls.
