In a cooperative research effort between The Puerto Rico Center of Energy and Environment Research, Kaiser Aluminum and Chemical Corporation and The Trane Company, a six month study was made of the seawater corrosion performance of various aluminum materials to test their suitability for use in seawater heat exchangers. The materials tested included bare 3004 tubes, 7072 Alclad 3004 tubes and bare and zinc diffusion treated 3003 extrusions from a brazed aluminum, plate-fin heat exchanger extrusions from a brazed aluminium, plate-fin heat exchanger developed by The Trane Company. The test materials were exposed to 1.8 m/sec flowing seawater aboard an open ocean test facility moored 3.4 km off the southeast coast of Puerto Rico. After six months exposure, the average corrosion rates for most varieties of aluminum materials converged to a low value of 0.015 mm/yr (0.6 mils/yr).
