Advantages
Ultra‑High Density
High density (~17.0–18.0 g/cm³) provides maximum mass in limited space for balance and shielding applications.
Ductility
Tungsten's strength and Ni–Cu binder's ductility reduce brittleness while maintaining mechanical reliability.
Machinability
Improved workability over pure tungsten allows precision machining into complex shapes and tight tolerances.
Corrosion Resistance
Nickel and copper matrix enhances corrosion resistance for wider industrial use.
Applications
Aerospace & Aviation
Used for aircraft counterweights, rotor balancing, and precision components where high density and stability are critical.
Radiation Shielding
Ideal for medical, nuclear, and industrial radiation shielding applications due to its high mass and mechanical strength.
Industrial Equipment
Used in vibration dampers, precision molds, and machinery components requiring high density, wear resistance, and dimensional stability.
Defense & Ballast
Applied in military and marine applications such as ballast weights, projectile components, and armor balancing.
Scientific Instruments
Used in high-precision instruments and experimental devices requiring compact mass and consistent mechanical performance.
