Description

Tungsten Carbide With Cobalt Binder CAS NO 12774-15-1 is a high-performance composite material, also known as cemented carbide, where ultra-hard tungsten carbide particles are metallurgically bonded by a cobalt matrix. This combination is critical for delivering exceptional hardness, wear resistance, and structural integrity under extreme conditions. It is an essential engineered material for industries requiring durable cutting, forming, and wear-resistant components, such as metalworking, mining, oil & gas, and precision engineering.

Application

• Cutting Tools & Inserts: Primary material for lathe tools, milling cutters, drills, and indexable inserts for machining steels, cast iron, and superalloys.
• Wear Parts & Tooling: Used in dies, punches, forming tools, and wear plates for metal stamping, drawing, and extrusion processes.
• Mining & Construction Tools: Key component in drill bits, road planning picks, tunnel boring machine cutters, and other rock drilling equipment.
• Oil & Gas Drilling Components: Manufacture of stabilizers, drill bit inserts, and other downhole tools requiring abrasion and erosion resistance.
• Precision Wear Components: For seals, bearings, valve seats, and nozzles in high-wear industrial applications.
• Abrasive Waterjet Nozzles: Fabrication of nozzles capable of withstanding high-pressure abrasive slurry.
