The main applications for the engineering grades 90-10 and 70-30 copper-nickel alloys are in seawater piping, heat exchangers and condensers. The main industries are marine-based and cover thermal desalination, offshore oil and gas, power generation and commercial and naval shipping. Copper-nickel alloys are also used for hydraulic tubing, including brake tubing.
