Copper Nickel 90/10 Bars are composed of around 90% Copper (Cu) and 10% Nickel (Ni), with minor additions of Iron (Fe) and Manganese (Mn) to boost strength and corrosion resistance. This alloy is known for its remarkable resistance to seawater, brine, and marine atmospheric conditions. Typically, the mechanical properties include a tensile strength ranging from 275 to 350 MPa, a yield strength of 100 to 150 MPa, and impressive ductility with good elongation. These bars maintain their strength and integrity even under varying temperatures, pressure, and saline exposure, making them perfect for precision machining and challenging industrial settings.
