A composite section features a base of light-weight metallic material as section component and at least one further profiled section component, in particular a profiled strip of another metallic material which is joined metallically as a surface layer to the base section during an extrusion process. Projecting out of the inner-lying face of the profiled strip and directed at the base is at least one projection and/or an additional element which are/is embedded in the base. Each additional element may delimit an undercut space which is filled in an interlocking manner by metallic material of the base.

A composite section (10) features a base (12) of light-weight metallic material as section component and at least one further profiled section component, in particular a profiled strip (18) of another metallic material which is joined metallically as a surface layer to the base section during an extrusion process. Projecting out of the inner-lying face (21) of the profiled strip (18) and directed at the base (12) is at least one projection and/or an additional element (23) which are/is embedded in the base (12). Each additional element (23) may delimit an undercut space which is filled in an interlocking manner by metallic material of the base (12).

Heat exchanger for cooling semi-conductor components or the like equipment features cooling fins that are spaced apart, attached to and project out from a base section of extruded aluminum or another light metal, each fin being secured in a groove or the like recess in the base section, The cooling fins are in the form of cooling-fin plates made of thin-gauge strips of material and, as viewed in longitudinal cross-section, are profiled at least in the region where they join the base section.

In a system comprising at least two conductor rails, in particular composite sections each featuring a rail-shaped load-bearing section and at least one strip-shaped section of another metal of greater wear resistance joined to the matrix of the load-bearing section, the ends of pairs of neighbouring rails are connected electrically by at least one conductor of variable length. The ends of the conductor rails are bent out of the central axis (M) of the conductor rail and led parallel to and a distance (n) displaced from that axis, such that the strip-shaped section of one conductor rail end is approximately aligned with the strip-shaped section of the other conductor rail away from the rail end; the conductor rail ends are joined in such a manner that they can move with respect to each other along the axial direction.
