Description

A high strength Mg free tube alloy suited for controlled atmosphere brazing.


The FA7929 alloy is designed as a high strength alloy with good corrosion resistance suitable for welded or folded tubes. In combination with suitable n-, header- and side plate alloys this material provides substantial down-gauging opportunities based on its high post braze strength. Furthermore, this product enables easy handling in the heat exchanger production process due to its good formability and outstanding brazeability. The product performance can be further adjusted by adding a sacrificial alloy on the waterside to improve the corrosion resistance.
