Tungsten carbide ball are widely used in ball valve and bearing. We can offer various grades and sizes. And the requirements of each procedure are stringent to ensure that the products produced must comply with your request. We adopt the advanced technical. The ball has the high endured causticity and high endure grind, which could improve the life of the bearing, while elevate the value of your products.
Typical Material composition: 6% Cobalt, 94% Tungsten Carbide.
But other compositions are available with Cobalt content up to 25%. Hardness reduces and toughness increases with increasing cobalt content.
Cobalt binder material is reasonably resistant to corrosion. The Cobalt binder will corrode in contact with water, but the effect is largely cosmetic in that the balls loose their polished appearance, with little effect on performance. De-ionised water does pose a more severe problem, as it can tend to promote 'leeching' of Cobalt from the binder. Erosion of the binder can be a problem when in contact with abrasive particles as may occur in some valve and pump applications.
