Tungsten Carbide (WC) Milling Balls (1-15 mm), 10-100 pcs/bag, MBWC

Tungsten Carbide (WC) Milling Balls—typically composed of 94 wt% Tungsten Carbide hard phase combined with a 6 wt% Cobalt metallic binder (often classified under industrial designations like YG6 or ISO K20)—represent the heaviest and most powerful grinding media available for high-energy ball milling. Because tungsten carbide is technically a cermet (a ceramic-metal composite), it bridges the gap between ceramics and alloys, providing unparalleled impact energy to shatter exceptionally hard, abrasive, or dense materials.

The key advantages of the WC milling balls are: (1) Ultimate Kinetic Energy: Because milling efficiency depends directly on the mass of the moving media, a planetary ball mill running at 600 RPM will pulverize a sample up to 300% faster when using tungsten carbide compared to standard steel or zirconia. This is critical for mechanical alloying, hard-facing material synthesis, and high-entropy alloy (HEA) production. (2) Shattering Refractory Materials: Tungsten carbide is the premier choice for processing materials that score or defeat other media types, including: geological ores & minerals, hard ceramics, and refractory metals.
