Cemented Carbide Material Grades

Cemented carbide, or hard metal, is a composite material that combines ceramic hardness with metallic toughness, making it highly versatile for a wide range of applications. BRC customises its cemented carbide through precise control of raw materials, chemical compositions, and production processes, ensuring products meet the rigorous performance demands of modern mills.

Applications

Used for wires, rod blocks, and composite roll systems, such as rolling rebars, finishing light sections, and narrow flats where precision and high surface quality are critical.

Benefits

Provides exceptional hardness and wear resistance for demanding applications. Its durability extends across various rolling scenarios, with superior resistance to mechanical stress, thermal degradation, and corrosive environments. These qualities make it a trusted choice for high-performance steel production processes. BRC calibrates and controls the cemented carbide manufacturing process by adjusting factors such as binder content and tungsten carbide (WC) grain size. We can customise these parameters to meet your exact requirements, delivering optimised performance tailored to your needs.

Choose our cemented carbide products for their unmatched reliability and extended component lifespan.
