Tungsten carbide (WC) particle is a tiny hard grain of a compound made of tungsten carbide,crucial for making strong, wear-resistant cemented carbides for cutting tools, abrasives, and armor; these particles vary greatly in size (from nano to micro) and are engineered with binders (like cobalt) to control hardness and toughness, offering extreme hardness, high melting point, and corrosion resistance, making them essential for high-performance materials.
