Product Description
cemented tungsten carbide rollers tungsten carbide wear parts
1,Description:
Tungsten carbide (WC) is a compound composed of tungsten and carbon. Here is an English description of tungsten carbide:
Tungsten carbide is a hard and dense compound known for its exceptional hardness and wear resistance. It is composed of tungsten (W) and carbon (C) atoms, with a chemical formula of WC. Tungsten carbide is often referred to as a cemented carbide or hardmetal due to its use as a cutting tool material.
Tungsten carbide is renowned for its remarkable hardness, ranking among the hardest materials known, comparable to or even surpassing the hardness of natural diamonds. It exhibits excellent wear resistance, making it highly suitable for applications that require cutting, machining, drilling, and grinding of hard materials such as metals, alloys, and composites.
The exceptional hardness of tungsten carbide is attributed to its crystal structure, which consists of a lattice of tungsten atoms with carbon atoms occupying the interstitial sites. This atomic arrangement results in a rigid and densely packed structure that enables tungsten carbide to withstand high compressive stresses and resist deformation.
