Nickel Clad Copper Bar
Nickel-clad copper bar is a metal composite material with copper as the core material and a uniform outer layer of nickel. Its core advantage is that it combines the high conductivity of copper with the corrosion resistance and solderability of nickel. Through precise composite bonding, it achieves complementary performance and optimized cost, making it widely used in electronics, electrical engineering, and chemical industries. The following is a detailed introduction:
Structural Characteristics of nickel clad copper bar
Typical Structure: Copper core (70%-90%) + Nickel layer (0.01-0.5mm thick, 10%-30%). Some high-end products will have an additional thin layer of nickel or gold plated on top of the nickel layer to further improve surface performance.
Composite Requirements: The nickel layer and copper core must be tightly bonded, without gaps or oxide layers, ensuring conductive continuity and structural stability, and preventing delamination during use.
Benefits
Combines high conductivity of copper with corrosion and wear resistance of nickel.
Reduces oxidation and tarnishing, enhancing reliability.
Extends service life in demanding environments.
Minimizes maintenance and replacement costs.
Nickel Clad Copper Bars are widely used in applications that require the excellent electrical and thermal conductivity of copper combined with the corrosion resistance, wear resistance, and durability of nickel.
