Uncoated CBN Powder

Alfa Chemistry is a professional supplier of advanced abrasives and technical services, dedicated to delivering high-performance solutions to meet the evolving demands of precision grinding industries. Among our product offerings, uncoated cubic boron nitride (CBN) powder stands out as a versatile and efficient abrasive material engineered for a wide range of fine grinding and superfinishing applications.

CBN is renowned for its exceptional hardness, thermal stability, and chemical inertness, particularly against ferrous materials. Our uncoated CBN powders offer optimal performance when used in resin, ceramic, and metal bonding systems, making them ideal for precision tooling and advanced material removal processes.

Key Features

• Superior Thermal Conductivity: It ensures rapid heat dissipation, protecting both the abrasive and the workpiece from thermal damage.
• Excellent Surface Integrity: It enhances surface finish quality, especially during the machining of hardened steels, tool steels, and nickel- or cobalt-based superalloys.
• Versatile Bond Compatibility: It can be integrated with various bond systems, including vitrified, resin, and metal bonds.
• Tailored Fracture Strength: Different product grades offer specific balances between toughness and friability, extending wheel life and improving dressing intervals.
• High Purity and Consistency: Engineered for uniform performance in both mechanical bonding and high-demand PCBN (polycrystalline cubic boron nitride) applications.
