Two chromium modified copper-nickel alloys have been developed which provide exceptional levels of impingement corrosion resistance in flowing seawater systems. The new alloys retain all the unique characteristics which make the copper-nickel alloys particularly attractive for condenser tube applications. In addition, they provide improved performance capabilities at normal condenser tube flow velocities and significantly increase the upper velocity limit at which copper-nickel alloys can be used effectively.

Abstract Copper Alloy No. C72200 was developed to improve on the performance of the copper-nickel condenser tube alloys. It is essentially 85-15 copper-nickel with additions of 0.8% iron, 0.5% chromium and 0.5% manganese. It has exceptionally high resistance to erosion and corrosion by flowing seawater. Its strength and other mechanical properties are similar to the older copper-nickel alloys (90-10 and 70-30). Alloy C72200 is used primarily for condenser and heat-exchanger tubing using seawater and for salt-water piping. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-449. Producer or source: Copper and copper alloy mills.

Abstract ANACONDA Alloy 706 (also known as Cupro Nickel, 10% 706) is a wrought 90% copper-10% nickel alloy developed to provide a material less costly than the copper-nickel alloys containing 20 or 30% nickel, but yet offering much of their excellent reliability. This was achieved by adding 1.25% iron to Alloy 706 to increase its resistance to corrosion by salt water. Alloy 706 is recommended where good mechanical properties, weldability and corrosion resistance are needed. It is widely used for plates, tubing and piping that must resist seawater. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-391. Producer or source: Anaconda American Brass Company.

The results of a series of investigations to assess the performance of a variety of alloys in small experimental condenser configurations at seawater velocities of 10 to 20 fps are summarized. They demonstrate that the addition of 1 percent aluminum increases the maximum velocity limits of copper-nickel alloys to 12–15 fps. Stainless steels, nickel alloys, and titanium are satisfactory for use at velocities of 20 fps, but many of these would be susceptible to pitting and/or crevice corrosion under stagnant conditions.
