Aluminum brass UNS C68700 has a copper content of not less than 76%. C68700 has especially good corrosion resistance in sea water and heat transfer. so It is a very popular heat exchanger alloy and condencer alloy in industry area, making it ideal for use in marine environments. ASTM B111 C68700 tube is widely used in the surface condenser, heat exchanger, and evaporators. The C68700 tube offers high strength, excellent corrosion resistance, and good creep resistance at elevated temperatures.
