Custom Nickel Clad Copper Wire | High-Temperature & Corrosion-Resistant Bimetal Conductor

Custom Nickel Clad Copper Wire

مقدمة

1. Nickel Clad Copper Wire is a high-performance bimetallic conductor featuring a thick, continuous nickel layer metallurgically bonded to a high-purity copper core. Unlike standard nickel-plated wire, the “clad” process creates a much heavier and more uniform nickel barrier that remains stable even under extreme mechanical stress and thermal cycling. This material combines the superior electrical and thermal conductivity of copper with the exceptional oxidation and corrosion resistance of nickel, making it the premier choice for applications in aerospace, military electronics, and harsh industrial environments where temperatures reach up to 600°C.

2. We offer fully customizable Nickel Clad Copper Wire tailored to your specific technical requirements, including a variety of cladding ratios (commonly 10%, 20%, and 27% by weight) and wire diameters. Our wire is engineered for excellent solderability, weldability, and mechanical durability, ensuring stable electrical performance in heating elements, high-temperature cables, lead wires for sensors, and oil-and-gas exploration equipment. All products are manufactured to meet rigorous industry standards (such as ASTM B355), providing consistent resistance and long-term reliability for your most demanding engineering projects.
