Boron Carbide

Inquire Now

Boron carbide is one of the hardest known synthetic materials, ranking just below diamond and cubic boron nitride in hardness. Characterized by its high strength, low density, excellent chemical stability, and outstanding wear resistance, boron carbide is widely recognized as a premier ceramic material in abrasive and high-performance industrial applications.

As a professional supplier of abrasives and technical services, we offer high-purity boron carbide products tailored to meet the rigorous standards of precision grinding, ballistic protection, and advanced ceramic applications.

Key Features

Exceptional Hardness: Mohs hardness of 9.3 enables high-performance abrasive capabilities, ideal for grinding, lapping, and polishing.
Low Density: Approximately 2.52 g/cm³, making it highly suitable for lightweight structural and protective applications.
High Thermal Stability: Melting point of ~2,450°C ensures excellent performance in high-temperature conditions.
Superior Chemical Inertness: Resistant to acids and most chemical agents, extending service life in aggressive environments.
Low Thermal Expansion: It provides excellent dimensional stability during thermal cycling.
