MSE PRO 5 mm Tungsten Carbide (WC-Co) Balls for Grinding and Milling, 1kg: Industrial & Scientific
Cobalt is the most compatible binder for cemented carbides [35]: mixed with WC, it creates a eutectic compound that lowers the melting temperature and thus the processing temperature (more than 2800 °C for pure WC versus 1300–1500 °C with adequate Co ad-ditions) [36]. Moreover, the wettability of the carbide phase by Co is excellent, and WC is
