For main steam turbine condensers seamless Cu-Ni tubes have been used. 90-10 Cu-Ni is often the first choice with the 70-30 alloy being used for the steam inlet zone. To avoid erosion corrosion due to abrasive particles 70-30 is better than 90-10 with 66-30-2-2 being the best choice where for example sand is carried in the cooling water.
