An Investigation on Corrosion Behavior of a Multi-layer Modified Aluminum Brazing Sheet

An Investigation on Corrosion Behavior of a Multi-layer Modified Aluminum Brazing Sheet

The corrosion behavior of a multi-layer modified aluminum brazing sheet (AA4045/3003Mod./AA7072/AA4045) was investigated. The results shows that, the existence of BDP, which forms at the interface between clad and core layer during brazing, changes the corrosion form of the air side of the material...
