- Material:
|
B4C / Boron Carbide
|
- Introduction:
|
Boron carbide (B4C) 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. |
-Typical Characteristics:
|
1. Exceptional Hardness 2. Out Standing Wear Resistance 3. Low Density 4. High Flexural Strength 5. Neutron Absorbing |
-Typical Applications:
|
1. Ballistic Armor 2. Neutron Shielding 3. Wear Resistant Tile 4. Sandblasting Nozzle |
