Boron Carbide
Description:
Boron Carbide is part of the most important group of non-metallic hard materials. Its outstanding properties are extreme hardness, corrosion resistance to many reactive chemicals, excellent hot strength, very low specific gravity and high elastic modulus. Boron Carbide is used for tool and die fabrication, finishing of ceramics and other hard materials, ultrasonic drilling, metallurgy, and nuclear technology.
