Product Description




Best Selling High Quality Boron Carbide for Bulletproof Vest Boron Carbide B4C Powder
Boron Carbide is one of the hardest materials known, ranking third behind diamond and cubic boron nitride. It is the hardest material produced in tonnage quantities. B4C's / boron carbide‘s Mohs hardness is around 9.5, melting point 2350℃, density 2.51g/cm3.




B4C boron carbide can be used to make steel, jewel, hard ceramic and other hard materials, and to manufacture wear-resisting parts, metal cutting tools, nozzles and neutron-absorbing rods,used as metal additive for compound materials for military planes and as raw materials for metal boride, metal ceramic,boron steel, boron alloy and for special welding and refractory materials.
