Description

2.0882 (CuNi30Mn1Fe) 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. It shows the following features and properties:

Excellent corrosion and pitting resistance in marine environments

Good strength and toughness

Resistance to biofouling

Readily weldable and fabricated
