UNS C71500 copper nickel alloy (also called cupronickel) includes 30% nickel, providing greater strength. The material promotes good creep resistance at elevated temperatures and is straightforward to machine, weld, and form. However, the main benefit of UNS C71500 is the alloy's resistance to corrosion in marine atmospheres. The product is suitable for various applications in the above-sea and subsea engineering sectors, including condenser tubes, pipework, flanges, valves, and pump components.
