Abstract: A brazeable metal sheet material for heat exchanger components is used for producing a heat exchanger by a controlled atmosphere brazing process. The metal sheet material is made up of a core material with a brazing layer at least on one side and a corrosion-reducing intermediate layer arranged between the brazing layer and the core material. The core material consists of an Al3000-series alloy or an Al6000-series alloy having a magnesium content of 0.1% to 1.5% by weight. The brazing layer consists of an Al4000-series alloy having a maximum of 0.2% magnesium by weight. The corrosion-reducing intermediate layer consists of an Al1000-series alloy or an Al7000-series alloy having 0.1% to 1.5% magnesium by weight.

Abstract: A brazed heat exchanger, for example a heat exchanger to be used in an air-conditioning system, preferably as a condenser, includes flat tubes extending between a pair of header tubes and fins arranged between the flat tubes. The components are produced from aluminum alloys, and are brazed together using an AlSi braze alloy. The aluminum alloys have a zinc content of no greater than 0.5% before brazing, and zinc from the aluminum alloys diffuses into the braze joints to result in braze joints having an average zinc content of no greater than 0.1%.
