Erosion-corrosion has been identified as a major cause of premature failure of copper alloy heat transfer tubing. Previous work has defined the enhanced resistance of Copper Alloy C72200 in resisting erosion-corrosion at both tube inlet ends due to turbulence and at downstream blockages which cause high localized water velocities. Many waters contain quantities of suspended entrained sand which can be of significance. The tests reported in this paper compare the performance of Copper Alloy C72200 (Cu-85, Ni-15, Cr-0.5) to that of Alloys C70600 and C71500, 90/10 and 70/30 copper-nickel, respectively, and Alloy C71640, a high iron-manganese 70/30 copper-nickel alloy. The latter has found application in desalination units in the Middle East where specific waters are high in suspended sand content. In these tests the performance of C72200 was superior to that of C70600 and C71500 and closely approached that of C71640.
