C70600 Copper Nickel, also known as 90/10 Copper Nickel, is a high-performance copper alloy composed of approximately 90% copper and 10% nickel, with small additions of iron and manganese to improve strength and corrosion resistance. Renowned for its exceptional resistance to seawater corrosion, erosion, and biofouling, C70600 is one of the most widely used copper-nickel alloys in marine and industrial environments. It also offers excellent weldability, good ductility, and reliable mechanical strength, making it easy to fabricate into a variety of components.
