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.
