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.

Corrosion Resistance
Good corrosion resistance in basic and neutral solutions. For acid solutions they resist up to pH 4.

Applications

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.
