Copper Nickel Suppliers - CuNi 90/10, 70/30, 2.0872, 2.0882
Copper-nickel alloy properties vary with composition. The two main copper nickel alloys are 90/10 (90% copper, 10% nickel) and 70/30 (70% copper, 30% nickel). The 70/30 is the stronger and has greater resistance to seawater flow, but the 90/10 will provide good service for most applications and, being less expensive, tends to be more widely used.
