Abstract
The invention relates to a series of extra strong and durable aluminium alloy brazing sheets with enhanced corrosion resistance for brazed heat exchangers. The alloy sheets are based on recycled materials and are suitable for manufacturing of fins, welded tubes, headers and sideplates. The alloy sheets showed improved corrosion performance with respect to pitting corrosion, excellent high temperature sagging resistance and post braze strength, and a good brazeability. By optimising the material combination of fin, tube, header and sideplates it is possible to produce a heat exchanger with adequate corrosion performance in SWAAT.
