Hot-pressed Boron Carbide Rod

Our hot-pressed boron carbide rods are made from a high-performance ceramic that we produce to the highest quality. Boron carbide is an extremely hard ceramic with good chemical resistance and thermal conductivity. These attributes make our Hot-Pressed Boron Carbide Rods suitable for demanding applications like abrasion-resistant linings, ballistic armor and lightweight structural components.
