Copper nickel supplier, manufacturer & exporter in India
Copper nickel, often called Cu-Ni alloy, is a unique combination of copper and nickel metals that offers excellent resistance to corrosion, especially in seawater environments. This makes it highly suitable for marine engineering, desalination plants, power generation, and chemical processing applications. The alloy typically contains 10% to 30% nickel and small amounts of iron and manganese, enhancing its strength and durability without compromising its corrosion resistance.
Copper-nickel products are highly valued for their thermal and electrical conductivity, anti-fouling characteristics, and long service life. Unlike pure copper, which can be softer and more prone to corrosion, copper nickel alloys maintain a strong structure while being resistant to harsh environments such as saltwater, brackish water, and industrial chemicals. They are widely used in shipbuilding for seawater piping, heat exchangers, condenser tubes, and other marine applications due to their ability to prevent biofouling and maintain structural integrity under high pressure.
