This pure nickel wire combines high thermal conductivity (70.2 W/m·K) with high electrical conductivity and low vapor pressure — performance that earns it a place in military, aerospace, medical, chemical and electronic industries. Nickel content is 99.2% minimum (Ni200) and 99.0% (Ni201). Produced on our own nickel-alloy line, every spool is inspected per batch before packaging.

| Per-batch inspection | Composition, diameter and surface checks per batch |
Thermal conductivity of 70.2 W/m·K (Ni200) and electrical resistivity of 0.096 μΩ·m (20°C) place pure nickel wire as an effective conductor of both heat and current — the combination demanded in electronic and thermal management applications.
Low gas content and low vapor pressure make the wire suitable for vacuum and precision service, where outgassing and contamination must be controlled. This property is confirmed against the application rather than claimed beyond the material's established behaviour.
The wire offers excellent resistance to corrosive environments, media and alkalis, including hydrofluoric acid service. It responds well to hot rolling, cold forming and machining, and is compatible with conventional welding, brazing and soldering processes.
Produced on our own nickel-alloy line, every spool passes chemical composition analysis, diameter inspection and surface checks in our in-house inspection process before packaging.
