Development of Aluminum Radiators Using the Nocolok Brazing Process - Corrosion Resistance of New Aluminum Radiators by Applying a Nocolok Brazing Process 870180

The prices of copper and solder are largely influenced by the global situations. On the other hand, bauxite, the raw material required in making aluminum radiators, is inexhaustibly available and its relatively steady supply is obtainable. With such an assumption, research and development of aluminum radiators started in or around 1960. However, we could not develop any new method of processing and aluminum alloy which could compete with copper-made radiators, particularly in corrosion resistance and cost. This resulted in delayment of its practical use. In 1984, we successfully manufactured aluminum radiators owing to NE process in which non-corrosive flux was used. and development of an alloy matching the NB process. This report describes the non-corrosive aluminum. radiator manufactured in the NB process.
