A method and device for the heat treatment of a profile, in particular an extruded profile for aircraft. The profile may be formed by one or more different, in particular curable, aluminium alloys. The method provides that at least two regions of a profile are subjected to a different heat treatment. The device includes a first chamber that encloses a first region of a profile and a second chamber that encloses a second region of the profile, wherein different temperatures can be set in the first and second chambers. The profile has at least two regions that each have different material properties and are formed by differential heat treatment.
