Tungsten Carbide Roller/Carbide rolls is a kind of metallurgical tool which consists of tungsten carbide and cobalt with high hardness and wear resistance. There are ideal for use in applications where strength, durability and longevity are factors. Tungsten Carbide (WC) is twice as strong as steel and is similar to corundum in hardness. It has a Young’s Modulus rating of 530–700 GPa (77,000 to 102,000 ksi) and the material is twice as dense as steel
