Tungsten Carbide (Cobalt Binder)

Description

Tungsten Carbide was originally developed for cutting tools, because it's extremely hard; it has great compressive strength and is three time more rigid than steel.

Benefits

These balls are characterised by high hardness, dimensional stability, high wear resistance and the ability to withstand significant levels of shock and impact. Although the Cobalt binder may corrode on contact with water, this is largely cosmetic and doesn't affect the overall performance.

Use

You'll find them in ball screws, check valves, flow meters (for example gas meters) gauging and checking instruments as well as ballpoint pens.
