ABSTRACT:
An improved aluminum alloy brazing stock material is provided for use in a tubeplate-and-center type evaporator within an automobile air conditioning system. The improved aluminum alloy brazing stock contains a unique aluminum alloy core material that has been clad on both sides with an appropriate aluminum-silicon brazing alloy. The inventive aluminum alloy core material is characterized by a higher copper concentration and a lower manganese concentration as compared to conventional aluminum alloys used in these types of automotive evaporator units. An air conditioning evaporator unit from the aluminum alloy brazing stock material of this invention is characterized by enhanced corrosion resistance. In addition, the brazing stock material of this invention is sufficiently ductile to be stamped at room temperature and exhibits good strength even over the extensive thermal cycling characteristic of an automotive environment.
