TUNGSTEN CARBIDE BALLS (HARD METAL)
CHEMICAL COMPOSITION: WC 94% Co 6% (ISO K20)
Balls made of this material are used for applications requiring extreme hardness and resistance to wear and abrasion, hard shocks and impacts.
The applications include special valves, flow meters, re-circulating ball bearing screws, linear bearings and balls for ball-point pens. They are also used often for minting, as pivots and points of comparators. They are also used for measurements or calibration of holes and measurement checking devices.
