Abstract
A composite aluminum alloy brazing sheet and methods of producing the brazing sheet are disclosed. The brazing sheet includes a non-heat treatable aluminum base alloy core containing zirconium, chromium and manganese as the alloying ingredients. Bonded to at least one of the major face surfaces of the core is an aluminum base alloy sheet containing silicon plus optional additions of copper, zinc and magnesium. The core alloy resists softening and sagging at brazing temperatures while retaining good mechanical properties after the brazing operation is completed.
