YN6 YG8 Tungsten Carbide Grinding Balls 25MM 30MM Cemented Carbide Milling Ball
Tungsten Carbide with Ni binder (6%) balls, they show slightly worse mechanical characteristics
but better corrosion reistance properties with respect to the Cobalt binder tungsten carbides.
Virgin powder is always used.

| Cemented carbide is the best material for the production of carbide tips in the medium and high pressure DTH hammer drill industry.
Carbide ball teeth are widely used in oil drilling and snow removal, snow plow machines and other
equipment. In addition, carbide balls can be also well applied in cutting tools and mining machinery,
road maintenance and coal drilling tools. carbide ball teeth for mining are mainly used as mining tools
in quarrying, mining and tunnels and civil buildings. |
