Chromium Modified Copper-Nickel Alloys for Improved Seawater Impingement Resistance

Abstract

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.
