Why Tungsten Alloy Blocks?

Tungsten heavy alloy blocks (WNiFe, WNiCu, WMo) are essential in industries requiring extreme density, radiation shielding, and high-temperature stability.

Key Advantages:

 Ultra-High Density (17–19.3 g/cm³) – Ideal for counterweights, ballast, and vibration damping.

 Radiation Shielding – Superior to lead in medical, nuclear, and aerospace applications.

 Machinable – Can be CNC-machined into complex shapes (unlike pure tungsten).

Corrosion & Heat Resistant – Performs in harsh environments (chemical, marine, high-temp).
