George Metals, located in Houston, USA, stands out as a top manufacturer and supplier of Copper Nickel 90/10 Forgings. These forgings are celebrated for their remarkable corrosion resistance, strength, and durability, especially in marine settings. Made up of 90% copper and 10% nickel, this alloy (UNS C70600) excels in resisting seawater, biofouling, and erosion-corrosion, making it perfect for tough operating conditions. George Metals offers a diverse selection of 90/10 Cu-Ni forged components, including flanges, rings, nozzles, and custom shapes, all crafted to meet international standards like ASTM B122/B171. These forgings are trusted in naval, offshore, desalination, and power generation applications.
George Metals’ Copper Nickel 90/10 Forgings consist of 90% copper, 10% nickel, along with small amounts of iron (1.5%) and manganese (1%) to boost corrosion and erosion resistance. This alloy boasts a tensile strength ranging from 275 to 380 MPa and a yield strength of 105 to 135 MPa, along with impressive ductility and toughness, even in sub-zero temperatures. These forgings are non-magnetic and maintain excellent mechanical properties in both freshwater and saltwater. Supplied in an annealed state, 90/10 Cu-Ni forgings are perfect for creating components that require reliability under cyclic loading and exposure to corrosive environments.
