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. |
