Copper nickel (CuNi) strips are high-performance alloys composed primarily of copper, with varying percentages of nickel—commonly 70/30 or 90/10 compositions. These strips are designed for electrical applications requiring a combination of excellent electrical conductivity, corrosion resistance, and mechanical strength. The copper content ensures efficient current flow, while nickel improves durability, resistance to oxidation, and thermal stability. Depending on the alloy grade, CuNi strips can withstand both marine and industrial environments, making them ideal for harsh operating conditions.

Applications

• Electrical busbars and connectors

• Switchgear and circuit components

• Marine electrical systems and shipboard wiring

• Power generation equipment

• Control panels and industrial instrumentation
