The Electrochemical and Metallurgical Properties of Materials Used for the Manufacture of Brazed Aluminium Heat Exchangers

The durability of an aluminium heat exchanger in a corrosive environment depends on the composition and combination of component materials. and the rate at which corrosion occurs will be influenced by the metallurgical and electrochemical characteristics of the individual components Using a simple multiple anodic polarising technique it has been possible to establish both the electrochemical characteristics of component materials. The results from experimental data have been used to design heat exchangers Accelerated corrosion testing of these heat exchangers confirmed predicted corrosion durability.
