Tungsten carbide balls are alloy steel balls made from hard refractory metal compounds and bonding metals through powder metallurgy. Tungsten carbide possesses a series of excellent properties, such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. Particularly, its high hardness and wear resistance remain almost unchanged even at temperatures of 500°C, and it still maintains high hardness at 1000°C.
