Abstract: Various illustrative embodiments of a multi-layer brazing sheet are provided. The multi-layer brazing sheet demonstrates improved corrosion resistance on its exposed air side surface.

Abstract: Heat treatable aluminum alloy strips and methods for making the same are disclosed. The heat treatable aluminum alloy strips are continuously cast and quenched, with optional rolling occurring before and/or after quenching. After quenching, the heat treatable aluminum alloy strip is neither annealed nor solution heat treated.

Abstract: A multi-layer metallurgical product comprising a core aluminum alloy, purposefully tailored through chemistry and processing route to resist recrystallization during the brazing cycle to intentionally exploit the higher strengths immediately after brazing of a deformed and recovered microstructure, the core aluminum alloy being positioned on one side to an aluminum alloy interliner designed to be resistant to localized erosion, which, in turn, is adjacent to a 4xxx cladding alloy. The multi-layer product can be fabricated at least in part via any multi-alloy ingot casting processes such as the Simultaneous Multi-Alloy Casting process or the Unidirectional Solidification of Castings process.

Abstract: The present invention relates to multiple layer aluminum brazing sheet having a core, a braze cladding, and an interliner therebetween that, when fabricated in the fully annealed condition (O-temper), forms a continuous and dense dispersoid band in the core in addition to having an additional sacrificial layer for exceptional post brazed corrosion resistance. This present invention also relates to the process used to fabricate these alloys.
