Brazeable metal sheet material, and heat exchanger with components made of the same

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.
