Tungsten Carbide Cobalt Binder Balls (Hard Metal) Wc 94% Co 6%

These balls are used in applications requiring extremely high hardness, wear and abrasion resistance, together with the ability of bearing strong knocks and impacts. Tungsten Carbides with Cobalt binder show good corrosion resistance into basic solution while they are not resisting into acid solutions.
