Boron carbide B4C1200# for precision mechanical polishing
Boron carbide is produced by high temperature smelting boric aid and carbon materails in electric furnaces.
Boron carbide is one of the world’s hardest manufactured materials. Its strong chemical bonds and hard surface minimize wear in rigorous environments. Boron carbides are often used in ballistic armor, taking advantage of exceptional hardness and low density. The hardness provides excellent protection, while the light-weight maximizes mobility. Additionally, the uniquely structured boron carbide can be used for neutron shielding. Low density Exceptional hardness Neutron absorbing
CAS Number: 12069-32-8
