Composition: Ni
Form: Insulated Wire
Material: Nickel
CAS Number: 7440-02-0
Commodity: Metals
Insulation:
Polyimide
Polyimide-Insulated Nickel Wire combines the corrosion resistance, thermal endurance, and electrical conductivity of nickel with the robust dielectric strength and chemical inertness of polyimide insulation. Suitable for extreme temperature and corrosive conditions, it is employed in aerospace, marine, and high-temperature industrial systems. Applications include heating elements, high-reliability leads for thermocouples, and wiring in vacuum furnaces. Industries value its oxidation resistance at high temperatures and mechanical stability in demanding environments. In research, it is used for studies on conductor stability in vacuum, long-term insulation performance, and thermoelectric response under cycling conditions. The insulated wire’s combination of metallic resilience and insulation integrity ensures dependable service in both industrial and experimental roles.
