Copper Nickel 70/30 Round Bar and Cupro Nickel 70/30 Hex Bars are primarily use when the most elevated level of precision are required alongside a brilliant completion. Cu-Ni 70/30 round poles are accessible in 1/4″ to 1 3/4″ width and satisfy ASTM B111 guidelines. Copper Nickel 70/30 UNS C71500 Round Bars. Cupro Nickel 70/30 Bus bars has great electric conductivity, erosion opposition and high formability.
Copper Nickel 70/30 is 70% copper, 30% nickel alloy with additions of iron and manganese. These elemental additions make it somewhat more resistant to corrosion and erosion and with slightly improved strength level than Copper Nickel 90/10, making it suitable for more demanding applications. In particular, its corrosion resistance is notably improved in high-velocity waters (up to 4.5m/s) and polluted seawater. Copper Nickel 70/30 is readily cold and welded without any special material. The most famous specifications to cover this alloy are the CN107 and C71500 designated, although the Naval Engineering specifications DEF STAN 02-780 or NES 780 offer tougher and strength controls on impurities and mechanical properties together with a mandatory impact value
