Tungsten Carbide Ball
Tungsten carbide ball has 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 slideways, gauging and checking instruments, and meters. Tungsten carbide balls are also used for ballizing, to work-harden and improve fretting fatigue strength.
Tungsten carbide balls are ideal for applications where extreme 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.titanium ballThe balls are made from 100% virgin tungsten carbide material.
They have the features of high hardness, high precision, high anti-rust capability, high wear-resistant and abrasive and so on.
The tungsten carbide balls have wide applications, like steel bearings, instruments, hardware, ball valves, toys, polishing, smash, decoration, and sealing,Bicycles, Motor, Machinery, Electric Tools, Sports Apparatus, Medical Equipment,Chemicals, Aviation, Perfume Bottles, Sprayers, Valves, Nail Polish, Body Jewelry,Mobile Phone Panels, and so on.
