Copper Nickel 90/10 flanges consist of about 90% copper and 10% nickel, along with small amounts of iron and manganese. This unique blend offers remarkable resistance to seawater corrosion, pitting, and erosion, along with impressive tensile strength, typically falling between 240–310 MPa, and an elongation of 30–40%. The alloy’s excellent thermal conductivity and resistance to biofouling make these flanges perfect for challenging marine and offshore environments.
