What Is Nickel Plated Copper Wire?
Nickel plated copper wire is a type of electrical wire where a layer of nickel is coated onto the surface of a copper conductor. This combination offers the high electrical conductivity of copper with the superior heat and corrosion resistance of nickel. It’s widely used in demanding environments such as aerospace, military, industrial heating systems, and high-temperature electronics.

Why Use Nickel Plated Copper Wire?
Nickel plating significantly enhances the performance of standard copper wire in harsh conditions. Here are the key benefits:
1. High-Temperature Resistance
Nickel plating allows the wire to operate at temperatures up to 450°C (842°F) or more without degradation—far higher than typical copper wire.
2. Corrosion and Oxidation Resistance
Nickel prevents copper from oxidizing, especially in high-humidity or chemically reactive environments, such as marine or industrial atmospheres.
3. Extended Service Life
The nickel layer protects the copper core, increasing durability and reducing maintenance or replacement needs.
4. Improved Solderability
Nickel-plated surfaces resist oxidation and provide better bonding during soldering—ideal for precision electronics and circuit boards.
Common Applications of Nickel Plated Copper Wire
Due to its durability and resistance to extreme conditions, nickel plated copper wire is used in:
-
Aerospace wiring: Jet engines, satellites, and avionics
-
Military and defense systems: Rugged field communications and vehicles
-
High-temperature electronics: Heating elements, sensors, and ovens
-
Battery packs: Especially in electric vehicles and lithium-ion systems
-
RF and EMI shielding: Used in coaxial and braided shield cables
