Abstract

A strip-shaped or plate-shaped composite metal object and a method for the production thereof. The composite metal object has at least two layers of the same metal. The layers have been brought by a heat pretreatment to a temperature such that a mutual diffusion bond has resulted through subsequent pressing of the layers against one another, while reducing the thickness by 5 to 25% and preferably 8 to 15%. A layer, which on the side thereof facing an adjacent layer has strip-shaped recesses, which are closed by the adjacent layer to form channels when the layers are pressed together, is used as one of the layers. The channels in the composite metal object allow the inclusion of additional elements before processed further to form an implement. The channels remain extensively preserved during the production and further processing of the composite model object.
