Tungsten cemented carbide balls are spherical products made of cemented carbide. Their core component is typically a tungsten carbide (WC) matrix, with metal binders such as cobalt (Co) and nickel (Ni). Their crystal structure is primarily determined by the phase structures of the tungsten carbide and the metal binder. I. Crystal Structure of Tungsten Carbide (WC) 1. Crystal Type: WC belongs to the hexagonal crystal system and has a typical hexagonal close-packed (HCP) structure. 2. Atomic Arrangement: Tungsten (W) atoms…
