About Tungsten Heavy Alloy

Tungsten Heavy Alloy

Tungsten Heavy Alloy for Nuclear, Medical & NDT

MarShield Radiation Shielding are experts in the in the customization of tungsten heavy alloy for the Nuclear Energy, Nuclear Medicine / Radioisotope, diagnostic imaging and non-destructive testing industries.

Why Tungsten?

Tungsten Heavy Alloy has a density of up to 18.89 g/cm3 vs. lead at 11.34 g/cm3.  It’s ease of mechanical processing / machining, high ductility and strength makes it a viable option for many applications where lead is not feasible whether it be for size reduction, maximizing weight in large or small cavities or for radiation shielding. Tungsten Alloy is strong and highly customizable into precision components.
