Tungsten Alloy Weight Block – High-Density Precision Ballast for Critical Applications

Tungsten alloy weight blocks are engineered components made from tungsten-heavy alloys (WNiFe, WNiCu) with densities ranging from 17.0 to 18.5 g/cm³. These blocks provide maximum mass in minimal volume, making them ideal for counterbalancing, vibration damping, and radiation shielding in aerospace, industrial, and medical fields.

Key Features & Benefits

Ultra-High Density – 50% denser than lead, 2.3X denser than steel.

Precision Machining – CNC-ground to tight tolerances (±0.01mm).

Corrosion Resistance – Withstands harsh environments (saltwater, chemicals).

Non-Toxic & ROHS Compliant – Eco-friendly alternative to lead or depleted uranium.

Customizable – Tailored sizes, shapes, and mounting features (holes, threads).
