Cupronickel tubes are copper-based alloy pipes with nickel as the primary alloying element, exhibiting a beautiful silvery-white luster due to the addition of manganese, iron, zinc, and other elements. Possessing high corrosion resistance, excellent seawater erosion resistance, superior cold and heat tolerance, along with high strength and good ductility, they are widely used in critical fields such as shipbuilding, marine engineering, petrochemicals, and precision electronic instruments.
