How can tungsten carbide achieve extremely high hardness?

The reason why tungsten carbide achieves extremely high hardness is due to its structure and chemical composition. The lattice structure of tungsten carbide is very strong and composed of tungsten and carbon atoms in equal proportions, giving it excellent hardness properties. In addition, the bonding strength of tungsten carbide is also very strong, allowing it to maintain its hardness under high temperature and high pressure. These characteristics make tungsten carbide an excellent wear-resistant material and widely used in engineering fields.
