Boron Carbide Ceramic

B4C

Boron carbide composite is a composite of boron carbide and silicon carbide which leads to an increase in strength and hardness as compared to other composite materials.

Excellent Abrasion & Wear Resistance

The high hardness and fine grain size of the boron carbide composite makes the material ideal for components subjected to severe abrasion and wear.
