YG6 YG8 Grade Cobalt Alloy Castings Tungsten Carbide Ball Shining Finish
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 attacks are usually on
the binder. Since other materials are 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.
Usage : ball pen , bearing , high precision instruments, hardness
test machine, head pressure, mine, decorations and other special
precision industry.
