- Product Definition
Tungsten alloy brick is high-density alloy blocks made from a high percentage of tungsten (typically over 90%), alloyed with elements such as nickel, iron, and copper, and sintered into rectangular or cubic shapes. They are primarily used in applications requiring compact volume with high mass or effective radiation shielding. These bricks feature robust structure, dimensional stability, and can be custom-made according to drawings.
- Key Properties
| Property Type | Specific Features |
| High Density | Density ranges from 17.0 to 18.8 g/cm³, much higher than lead and steel, enabling more compact designs. |
| Excellent Radiation Shielding | Superior shielding of gamma and X-rays compared to lead of the same volume, ideal for nuclear protection systems. |
| Good Mechanical Properties | High strength and rigidity, resistant to deformation, pressure, and wear. |
| Dimensional Stability | Low thermal expansion; maintains dimensional accuracy under high temperatures or stress. |
| Eco-Friendly & Safe | Free of radioactive elements, making it a green alternative to lead for radiation protection. |
