Tungsten carbide is approximately twice as stiff (high modulus of elasticity) as steel. Tungsten carbide has very high impact resistance and it has very high strength for a material so hard and rigid. Compressive strength is higher than virtually all melted and cast or forged metals and alloys.
Tungsten Carbide Physical Properties. The microhardness of the carbide is 17300 MPa, the elastic modulus is 710GPa, the compressive strength is 56MP, and the coefficient of thermal expansion is 6.9 × 10-6 / K. Tungsten Carbide is a black hexagonal crystal with metallic luster and hardness similar to diamond.
Tungsten carbide is known for its advantageous properties, such as its high melting point, high hardness, low friction coefficient, and chemical stability [ [1], [2], [3], [4] ]. Owing to these excellent mechanical properties, tungsten carbide thin films are used as wear-resistant coatings for mechanical parts, molds, and drilling tools [ 4, 5 ].
Tungsten carbide is a compound of tungsten and carbon, renowned in industry for its superior durability and high melting point (2,870 C).
