To enhance resource efficiency in automotive lightweighting, a cesium-free brazing flux was evaluated that effectively inhibits the magnesium-induced formation of high-melting compounds—commonly known as ‘flux poisoning’—thereby enabling the reliable joining of high-strength aluminum alloys.
Thermal management of electric vehicles is faced with challenges, as batteries need to be kept at a defined temperature range between 15°C and 35°C in order to function at peak performance throughout the life of a vehicle. The manufacture of such battery cooling systems involves controlled atmosphere brazing technology using noncorrosive flux. OEMs develop different battery cooler designs that require adapted fluxing methods.

During recent years, gel blockage in engine coolant systems with aluminum heat exchangers produced by CAB has gotten more and more attention in the automotive industry. A general understanding of gel formation processes in engine coolants and the role that flux residues on internal surfaces of brazed heat exchangers may or may not have is of significant interest.
In everyday practice we can encounter problems connected with brazing imperfections – often manifested as leaking. In order to identify the failure root causes, usually a detailed examination needs to be perform. Optical metallography is one of the most important tools for such an analysis.
