G4 Precision Tungsten Carbide Bearing Balls Tungsten Fishing
Carbide Beads 12.7mm
Tungsten carbide balls provide a binder percentage slightly higher
than the standard balls (7-9%).
They are available on demand.
The mechanical properties and corrosion resistance are a little
lower if compared to standard K20 balls.
Virgin powder is strictly used into this kind of production.
Features:
Superior wear resistance
High hardness and mechanical strength
Good corrosion resistance
High precision for tolerance
They're widely used in oil&gas, bearings, ball screws,valves and flow meters.pen,
spraying machines,pump,machinery parts and other industries.
| Grade | Density g/cm3 | Hardness HRA(hv) | T.R.S (M Pa) | Performances & applications recommended |
| YG6 | 14.9 | 89.5 | 2150 | Good Wear resistance, used for hard wood,processing original wood,aluminum section bar,brass rod and cast iron. |
| YG8 | 14.6 | 89 | 2320 | Suitable for the roughening of cast iron and light alloys and also for the milling of cast iron and low-alloy steel. |
Corrosion Resistance |
|---|
As a general rule Tungsten Carbides with Cobalt binder show good
corrosion resistance into basic solution while they are not
resisting into acid solutions. |
| Applications |
|---|
| Special and hydraulic precision valves, special bearings, couplers, flow meters, sprayers, recirculating balls, ball spindles, tooling machines, sliding rails, ballpoint pens, pin and tips for indicators, precision measurement instruments, medical instruments. They are used in naval, mining, petrol and coining industry. |
