Copper Nickel 70/30 Flanges are mainly made up of 70% Copper (Cu) and 30% Nickel (Ni), with small amounts of Iron (Fe) and Manganese (Mn) added to boost their mechanical performance and corrosion resistance. These flanges excel in high-velocity seawater and aggressive fluid environments. Notable mechanical properties include a tensile strength ranging from 350 to 450 MPa, yield strength between 150 and 200 MPa, along with good elongation and ductility. The alloy is also known for its excellent weldability and thermal conductivity, making it a great choice for flange applications in pressure, structural, and thermal transfer systems.
