Abstract
A description is given of a process for producing a metal plate having at least one embedded heating element and of the metal plate produced by the process. The heating element is arranged between two plate bodies, and the heating element is embedded in the plate bodies by rolling with material displacement. The adjacent sides of the plate bodies have a layer of aluminum or an aluminum alloy. After a heat pre-treatment at the re-crystallization temperature of the aluminum or the aluminum alloy, the plate bodies are pressed against one another to bring about a reduction in thickness, with which the plate bodies form a diffusion bond with one another and are integrally bonded to one another over the entire surface area thereof to form the metal plate to be produced. The process produces a metal plate as a whole with better thermal conductivity and a broader spectrum of use.
