Copper Nickel EFW Pipes are primarily composed of copper (90% or 70%) and nickel (10% or 30%), with minor additions of iron and manganese to enhance strength and corrosion resistance. These alloys are known for their remarkable resistance to seawater corrosion, erosion, and biofouling. In terms of mechanical properties, Cu-Ni EFW pipes typically offer tensile strength ranging from 310 to 500 MPa, yield strength around 100 to 150 MPa, and elongation between 30% and 45%. They also demonstrate good weldability and thermal conductivity. Their metallurgical stability and mechanical strength make them perfect for high-pressure and high-temperature applications, particularly in marine and offshore systems.
