Why cupro-nickel for heat transfer solutions?

High corrosion resistance

Cupro-nickel alloys are resistant to humidity, non-oxidising acids, lies and saline solutions, organic acids as well as to dry gases such as oxygen, chlorine, hydrogen chloride, hydrogen fluoride, sulphur dioxide and carbon dioxide. There is no risk of stress corrosion cracking and their susceptibility to both selective corrosion and pitting corrosion is extremely low. The resistance of these alloys is based on a stable surface layer resulting from the addition of alloying constituents. High mechanical strength along with high corrosion and erosion resistance offer the use of cupro-nickel for a variety of maritime and offshore applications.

Use with seawater

Due to their excellent corrosion and erosion resistance cupro-nickel alloys have for many decades been successfully used in heat exchangers dealing with seawater or other aggressive water. Typical applications are seawater desalination, air conditioning, cooling, heat supply in marine applications as well as chemical process engineering.

Common cupro-nickel alloys in thermal engineering are CuNi30 and CuNi10
