DESCRIPTION
High-Density Tungsten Alloy Block /Tungsten Alloy Brick– The Ultimate Material for Extreme Applications
High-density tungsten alloy blocks (typically WNiFe, WNiCu, or WMo compositions) are engineered materials with a density range of 17.0–19.3 g/cm³, offering unparalleled mass, strength, and stability. These blocks are precision-sintered and machined for critical applications where space efficiency and performance are paramount.
Key Features & Benefits
✅ Ultra-High Density – Up to 2.5X denser than steel and 50% denser than lead, enabling compact, heavyweight designs.
✅ Superior Shielding – Ideal for blocking X-rays, gamma rays, and neutrons in medical and nuclear environments.
✅ Exceptional Strength – High tensile strength (900–1200 MPa) and hardness (28–32 HRC) resist deformation under extreme loads.
✅ Machinability – Unlike pure tungsten, alloys can be machined into complex shapes using carbide tools.
✅ Corrosion Resistance – Withstands harsh chemicals, saltwater, and high temperatures.
