Nickel Clad Copper Stranded Wire

Raytron NCC stranded wire operates continuously at 400°C to 750°C depending on nickel cladding thickness (10-30% nickel content). The pure nickel cladding layer (melting point 1455°C) creates an oxygen barrier that protects the copper core. In contrast, bare copper stranded wire begins oxidizing above 150°C and fails rapidly above 250°C.

NCC stranded wire offers superior flexibility for applications requiring repeated bending or movement — such as aerospace wiring harnesses, robotic cable assemblies, and marine vessel cable runs. The stranded construction provides 3-5× better flex life compared to solid NCC wire of equivalent cross-section while maintaining 90% IACS conductivity.

Yes. The metallurgically bonded nickel cladding is highly resistant to salt spray, ammonia, and chloride-ion corrosion. NCC stranded wire is the preferred conductor for marine vessel engine room wiring, offshore platform instrumentation cables, and submarine communication systems where simultaneous high-temperature and high-corrosion resistance is required.

Raytron NCC stranded wire is available in 7-strand, 19-strand, and 37-strand configurations with individual wire diameters from 0.3mm to 2.0mm. Overall cable diameters range from 0.5mm to 20mm. Nickel content is customizable between 10-30% based on the temperature and corrosion requirements of your application.

NCC uses mechanical cladding to create a metallurgical bond between the nickel layer and copper core. This produces a thick (50-300μm), pore-free, and uniform nickel layer that will not peel under sharp bending or thermal cycling. Electroplated nickel copper has a thin (5-25μm), porous layer that is prone to peeling under thermal shock. For applications above 200°C or in corrosive environments, NCC stranded wire significantly outperforms plated alternatives.
