Product Description
Tungsten Nickel Copper (W-Ni-Cu) alloy is a high-density, non-magnetic material that offers excellent strength, corrosion resistance & electrical conductivity. Unlike W-Ni-Fe alloys, W-Ni-Cu is non-magnetic, making it ideal for applications in electronics, medical devices, and shielding materials for sensitive instruments.
With a high tungsten content (90-95%), this alloy provides superior mechanical properties, thermal stability & radiation absorption, making it a key material in industries such as aviation, nuclear, and defense.
Features & Properties
✔ High Density – Ranges from 17.0 to 18.5 g/cm³
✔ Non-Magnetic – Suitable for medical & electronic applications
✔ Corrosion & Wear Resistance – Ideal for marine & industrial environments
✔ Good Electrical Conductivity – Excellent for electronic components
✔ High Strength & Toughness – Can withstand high stress & impact
