Abstract

A method for producing a composite part is provided. The method includes a first and at least one second part, wherein the first part at least in part is made of a first metal and the second part at least in part is made of another metal that has a lower melting temperature than that of the first metal. Composite parts produced by the method are also provided. The method for producing composite parts which have an improved load-bearing capacity and yet low weight, is achieved by the fact that at least one breakthrough encompassing a breakthrough collar is introduced into the first part and the second part is non-positively and/or positively moulded onto the first part at least in the area of the breakthrough and the breakthrough collar by heating the second part and applying pressure to said second part.
