A metallurgical product consists essentially of 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 bonded on one side to an aluminum alloy interliner designed to be resistant to localized ero sion, which, in turn, is bonded to a 4xxx cladding alloy. |
