Copper Nickel 70/30 forgings are made up of roughly 70% copper and 30% nickel, with small amounts of iron and manganese added to boost strength and corrosion resistance. This alloy boasts impressive mechanical properties, including high tensile strength (around 340-480 MPa), good yield strength (130-260 MPa), and a melting point of about 1170°C. It excels in resisting seawater corrosion, stress corrosion cracking, and erosion. Additionally, the alloy offers good ductility and weldability, making it perfect for complex shapes and demanding environments that require durability and a long service life.
