Copper-nickel

UNS C70600 - CW352H

CuNi10Fe1Mn is a copper-nickel alloy containing 10% nickel, also known as 90/10. Iron is a critical additive; it enhances corrosion resistance in seawater by stabilizing the protective oxide film that forms on the surface. It can be used in pressure vessels up to 300 °C. Offering an excellent cost-performance ratio, it is the most widely used grade for marine piping, condensers, and heat exchangers.
