Fundamentally, a tungsten carbide industrial roller is a high-performance industrial roller that utilizes carbide materials (such as tungsten carbide) to form its functional working surface. Carbide industrial rollers typically consist of two components: 1. The roller body substrate 2. The carbide working layer

The hardness of carbide rollers is usually closely related to the alloy composition used. Carbide rollers are mainly composed of elements such as tungsten, carbon and cobalt, and different alloy formulas will affect their hardness. Specifically, the hardness of carbide rollers is usually between 55-80 HRC (Rockwell hardness C scale).

The core components of carbide rollers are metals and compounds such as tungsten, cobalt and carbon. Tungsten, as one of the main raw materials of carbide, has extremely high hardness and wear resistance, while cobalt, as a binder, plays a role in increasing the toughness and thermal stability of the alloy. The prices of tungsten and cobalt are high in themselves, which greatly increases the production cost of carbide rollers.
