Case Study: Corrosion Failure of Yellow Brass Tubing in Radiator Application

Several radiators used for locomotive engines, manufactured from a 65/35 copper/zinc yellow brass tube, were found to have leaking problems shortly after manufacture. The radiators were found to experience widespread leaks at varying locations during pressure testing conducted before use in service. A large population of radiators produced during the same production cycle (approximately 80%) experienced leaks. The radiators were returned to the...
