70/30 Copper Nickel Alloy (UNS 71500) is a 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 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.

90/10 Copper Nickel Alloy
90/10 Copper Nickel Alloy (UNS C70600) offers superior resistance to general corrosion and marine water attacks. It resists corrosion by fast moving water. It has nominal temperature coefficient of electric resistance. Alloy 90/10 prevents stress corrosion cracking and pitting and crevice corrosion.
Application 90/10 Copper Nickel Alloy (UNS C70600) is a 90% copper, 10% nickel alloy that also contains small but important additions of iron and manganese to enhance overall strength corrosion resistance. This, combined with high ductility and toughness, makes it a popular grade for marine, architectural and industrial applications.
