The invention relates to a strip of corrugations ( 2 ) for brazed plate and fin heat exchangers of the type with partial offset, comprising a series of zones for brazing on a first separation sheet ( 1 ), a series of zones for brazing on a second separation sheet ( 1 ) adjacent to the first separation sheet ( 1 ) and a series of wings ( 13, 14 ), said wings forming the fins, of which at least one of the wings ( 14 ) of a corrugation is inclined without being perpendicular to the separation sheets ( 1 ) and of which at least one of the wings ( 13 ) has at least one section perpendicular to the separation sheets ( 1 ) and a brazed plate or fin exchanger comprising said corrugations.
