The descript Tungsten Cobalt Alloy Valve Balls
Tungsten carbide balls are also called cemented carbide balls, bearing balls or just simply carbide balls. High hardness and dimensional stability make tungsten carbide balls the preferred choice for precision hydraulic valves, high-load bearings, inertial navigation systems, ball screws, linear bearings in sideways, gauging and checking instruments, and meters. We can manufacture and supply tungsten carbide balls of different diameters, different tungsten carbide grades or chemical compositions, different surface conditions, both in sintered blank and fine grinding
The Application of tungsten carbide ball
The application range is wide,such as:precision parts punching stretching,precision bearings,instruments,meters,pens,spraying machine,water pump,machinery fittings,valve,brake pump,extruding hole,oil field,laboratory, hydrochloric acid hardness measuring instrument,fishing gear,weight,decoration,finishing hightech industry.
The characteristics of tungsten carbide ball
Tungsten carbide balls are ideal for applications. It hardness must be accompanied by high resistance to wear and impact. They are well-suited to elevated temperatures, corrosion, humidity, abrasion, and poor lubrication conditions.
The working process of tungsten carbide ball
Heat treating: This high temperature process hardens the ball.
Grinding or polishing: The ball is then ground to the approximate diameter of the finished tungsten carbide balls. This polishing process the ball to the exact size required.
Dimensions:as per drawings
