The Development of a Brazing Sheet Core Alloy with Excellent Post Braze Properties

Abstract:

The heat exchanger market requires aluminum brazing sheet that offers a good balance of properties, namely: corrosion resistance, brazability, and post braze strength. A new long life brazing sheet alloy which has attractive properties in the post braze condition has been developed. Specifically, higher post braze strength and improved air side corrosion resistance has been obtained. In addition, a deeper understanding of dense precipitate band (DPB) formation in higher Si containing core alloys during brazing has been developed. The new alloy will lead to improvements in radiator tube stock performance.
