    • The invention relates to a brazing metal sheet consisting of a series AA3xxx aluminum alloy core sheet, coated, on at least one surface, with a cladding layer made of a first so-called "intermediate aluminum alloy" containing 0.35 to 1.8 wt% manganese, less than 0.3 wt% of each of other elements, and a total of 1 wt% aluminum residue. Said series AA3xxx cladding layer is itself coated with a second series AA4xxx alloy cladding layer in which the alloy of the core metal sheet is selected, and the core metal sheet developed, such as to have an essentially recrystallized structure after brazing. The invention also relates to the use of such a metal sheet for manufacturing a "supercharge air cooler" heat exchanger or passenger compartment air conditioner "evaporator" heat exchanger, and to said exchangers themselves, manufactured from said metal sheets.
    • 本发明涉及一种由AA3xxx系列铝合金芯片组成的钎焊金属片,在至少一个表面上涂覆有由含有0.35-1.8wt%锰的第一种所谓“中间铝合金”制成的包覆层, 小于0.3重量%的每种其他元素和总共1重量%的铝残余物。 所述系列AA3xxx包覆层本身涂覆有第二系列AA4xxx合金包覆层,其中选择了核心金属片的合金,并且核心金属片发展成例如在钎焊之后具有基本上再结晶的结构。 本发明还涉及这种金属板用于制造“增压空气冷却器”热交换器或乘客舱空调“蒸发器”热交换器以及由所述金属板制造的所述交换器本身的用途。
