SPECIAL OFFER FOR SERIES 3xxx STRIPS FOR PRODUCTION OF CAR HEAT EXCHANGERS High heat conductivity of aluminum and aluminum alloys in combination with low density cause, that such material becomes ideal for heat exchangers manufacturing in an automotive sector. From the whole 3xxx series, the most interesting is 3003 alloy because of its good corrosion resistance, high strength properties and excellent shape forming. The current trend in the automotive market is to reduce the size and weight of heat exchangers, and then cost reduction, forces aluminum producers to search for new solutions in the field of metal properties improvement. The improvement of 3003 alloy in terms of corrosion resistance, strength after soldering and resistance to high temperatures became a main goal of aluminum producers for automotive sector. Presently aluminum alloys used for production of heat exchangers are alloys, modified in terms of client technical requirements. We are the manufacturer of materials for automotive industry, which are based on series 3003 alloys.
