Due to its great resistance to erosion, corrosion, pitting corrosion, and oxidation, along with good strength, workability, and weldability, Cu-Ni 70/30 Tubes are a common type of copper-nickel alloy used in industry. The marine and offshore industries are where the alloy is most commonly used. Nickel makes up 30% of the alloy, which is composed of 70% copper. It's well-known for being resistant to corrosion and erosion as well. Because of water velocity and contaminated seawater, it has excellent corrosion resistance.
There are two different kinds of copper-nickel alloys: 70/30 and 90/10. Due to the substantial levels of manganese and iron present, copper-nickel 70/30 is extremely resistant to corrosion caused by seawater.
A metal used in cryogenic applications is cupro-nickel. Its great ductility retention and thermal conductivity at very low temperatures make it the perfect material for heat exchangers in freezing facilities when utilized in cryogenic processing and storage equipment.
Despite having a high copper content, cupronickel exhibits a silvery chrome tint. Copper-nickel is utilized in seawater systems and maritime equipment such as pipelines, heat exchangers, and condensers due to its exceptional corrosion resistance. High-quality hulls, shafts, and propellers are frequently constructed from this material. Other uses for this material include electrical, chemical, petrochemical, and military equipment.
