Abstract: The present invention is directed to a brazing sheet comprising an aluminum 3xxx series core alloy wherein at least one side thereof is provided with an aluminum clad material comprising from 0.7-2.0% Mn and 0.7-3.0.0% Zn, wherein the clad is capable of being used as an Inner-liner of a heat exchange product. In one embodiment one side of the core alloy is provided a material that comprises from 0.7-2.0% Mn and 0.7-3.0% Zn and the other side of the core is provided with an aluminum alloy comprising at least 5.5% Si. Thee are further provided methods for preparing brazing sheets as described herein as well as methods for use of brazing sheet materials including as tube stock and as heat exchangers, as well as other applications.

Abstract: The present invention provides an aluminum alloy brazing sheet material, particularly suitable for charge air cooler applications, comprising a core alloy and a clad brazing alloy, as well as to methods for their manufacture and use. The present invention also provides a method for increasing the yield strength of brazing sheet materials.
