Quality Tungsten Carbide Valve Ball Cooperate With Valve Seat Under 0.36 KGN/CM
Tungsten carbide balls are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves and flow meters. These balls are also used for coining and as pivots, detents and tips for gauges and tracers. Tungsten carbide itself is practically inert and extremely strong. Any attack is usually on the binder. Since other material is less expensive, the selection of tungsten carbide solely for corrosion resistance is usually not justified. In highly corrosive conditions, carbides with a more resistant binder can be supplied.

Composition
The tungsten carbide ball is based on a high hardness refractory metal carbide (WC, TiC) micron powder, with cobalt (Co) or nickel (Ni), molybdenum (Mo) as a binder, in a vacuum furnace or Powder metallurgy products sintered in a hydrogen reduction furnace, currently available in the series of hard alloys YG, YN, YT, YW.
Category
Tungsten carbide balls mainly include blank balls, fine grinding balls, punching balls, bearing balls, valve balls, non-magnetic balls, Monel balls, through-hole balls, measuring balls, scratching balls, and ball beads.

Feature
Cemeted carbide balls have high hardness, wear resistance, corrosion resistance, bending resistance and harsh environment, which can replace all steel ball products. The hardness of the cemented carbide ball is ≥90.5, and the density is 14.9 g/cm3.
Grade and Composition:
The common grades of cemented carbide balls are YG3, YG6, YG6X, YG8, YG8X,YG13. The most common are YG6 and YG8.
