Cupro Nickel Hydraulic Fittings are mainly made up of copper with 10–30% nickel, often mixed with small amounts of iron and manganese to boost strength and corrosion resistance. This unique blend offers remarkable resistance to seawater, brine, and stress corrosion caused by chlorides. On the mechanical side, they provide good tensile strength, toughness, and ductility, making them ideal for high-pressure hydraulic systems. These fittings also maintain their stability across varying temperatures and pressures. Their natural resistance to erosion and biofouling ensures a long service life, while precision engineering secures leak-free connections in critical hydraulic applications.
