A composite section features a profiled load-bearing component made of light weight metal and at least one profiled strip of another metal which exhibits high resistance to wear and which is metallically bonded to the profiled section during extrusion; the said composite section is intended in particular for use as a conductor rail and has a sliding contact surface defined by the profiled strip. At least one profiled strip (20) is embedded in the composite section approximately perpendicular to or inclined to the sliding contact plane (E). A profiled strip (20) runs on each side of the longitudinal axis (A) of the composite section (30) a distance (n) from it.
n profilé composite comprend un élément porteur profilé fait de métal léger et au moins une bande profilée d'un métal différent, qui a une résistance élevée à l'usure et qui, lors de l'extrusion, forme un lien de type métallique avec le profilé. Le profilé composite est notamment destiné à servir de rail de contact et comprend une surface de contact glissant constituée par la bande profilée. Le profilé composite comprend au moins une bande profilée (20) approximativement perpendiculaire ou inclinée par rapport à la surface de contact glissant (E). Il y a une bande profilée (20) sur toute la longueur, et des deux côtés de l'axe longitudinal (A) du profilé composite (30) à une distance (n) de celui-ci.
