Heat & Corrosion Resistant
Nickel Clad Copper For Extreme Environments
Operating temp up to 400°C+, superior chemical stability. Designed for extreme environments like aerospace and petrochemicals.
RAYTRON specializes in high-performance Nickel Clad Copper (NCC) wire, designed for extreme temperature environments and severe oxidative conditions. By metallurgically bonding a protective nickel layer over a highly conductive copper core, our NCC conductors ensure stable electrical performance without degradation at elevated temperatures. RAYTRON NCC wire is a preferred choice for EV battery tabs, aerospace electronics, and high-temperature industrial heating cables, offering superior corrosion resistance and weldability.

What is Raytron NCC?
Raytron NCC (Nickel Clad Copper) is a bimetallic conductor available as round wire, strip and foil. Typical conductivity ranges from 70-85% IACS depending on nickel ratio. It is used in high-temperature, corrosive and high-reliability contact applications where pure copper or nickel alone cannot meet combined performance requirements.
Manufacturing Process
This product is manufactured using Clad & Weld process with metallurgical bonding. It is NOT electroplated.
Metallurgical bonding creates a permanent metallurgical connection, ensuring stable reliability compared to electroplating. This enables excellent weldability, designed to resist peeling during bending, and stable performance under thermal cycling conditions.
NCC vs Bare Copper - The Extreme Challenge
In heat and corrosion, copper's limits are perfectly covered by nickel

💡 NCC is an engineered solution to keep copper core unoxidized above 400°C
Fearless of Heat
Pure nickel layer with 1455°C melting point effectively blocks oxygen, protecting inner copper conductor for operation in extreme temps.
Chemical Shield
Highly resistant to salt spray, ammonia, and acidic gases, making it the preferred conductor material for marine engineering and chemical plants.
Better than Plating
Cladding process creates a metallurgical bond designed to resist delamination under specified forming and bending conditions, addressing the peeling risk of plated products. Final performance must be validated for the target application.

Frequently Asked Questions
Technical Details & Selection Guide
What are the main application areas for Nickel Clad Copper?
NCC is primarily used where both good conductivity and high temperature/corrosion resistance are required. Typical applications include aerospace wiring, cables in extreme heat, petrochemical sensor leads, and electronic component pins requiring high surface quality to prevent oxidation.
What is the maximum operating temperature of NCC?
NCC can operate long-term at temperatures up to 400°C-750°C (depending on nickel thickness) without severe oxidation or performance degradation. In contrast, bare copper begins to oxidize rapidly above 150°C.
Can the nickel layer thickness be customized?
Yes, we can control the nickel layer thickness according to customer needs, typically with nickel content between 10%-30%. Thicker nickel layers offer better corrosion and heat resistance, while thinner layers favor cost control and conductivity.
What are the advantages of Nickel Clad Copper over Nickel Plated Copper?
NCC uses a mechanical cladding process, resulting in a thicker, pore-free nickel layer that is metallurgically bonded to the copper core. Compared to electroplating, the nickel layer is designed to resist delamination under specified forming, bending and thermal-cycle conditions; final performance must be validated for the target application.
