Copper Nickel C71500 (CuNi30MnFe1) is a copper nickel alloy with limited additions of manganese and iron to increase the strength. Copper Nickel 70/30 is also insensitive to stress corrosion.
Although this alloy was already known by the Chinese in the 9th Century, it did not become popular until the 1920’s when it was developed for naval applications in seawater condenser systems.
The addition of iron helps grain refining and increases the erosion resistance with flowing seawater.
It retains its strength well at moderately elevated temperatures, has good cold and hot working properties and is easily weldable.
The alloy is now used in a wide spectrum of applications, ranging from piping for seawater, cladding for offshore platforms and underwater cages for fish farming.
Being high in copper Copper Nickel 70/30 has anti-bio-fouling properties in seawater, and more recently, has been proven to have anti-microbial applications in hospital environments to combat the spread viral bacteria.
