W-Heavy Alloys

Tungsten Heavy Alloys [WNiFe and WNiCu]

Tungsten heavy Alloys: high-density materials with exceptional properties

Tungsten heavy alloys are high-performance tungsten-based materials that impress with their extreme density and outstanding mechanical properties. The combination of tungsten with additional elements such as nickel, iron, copper and molybdenum produces materials that are ideal for a wide range of industrial and military applications.

MOLYTUN GmbH offers these tungsten heavy alloys under the brand names DensM® and DensM® P, which are tailored to specific requirements.

For detailed information on the material properties, available dimensions and tolerances, please refer to the following table or the corresponding material data sheets.
