Abstract
The invention concerns a method for making a composite metal product by adding at least one substance to said product, which consists in using a metal product in the form of a continuous strip (1) moved in a vacuum chamber (2), applying the substance on said strip and diffusing said substance at least partially into the strip when it is passing in the vacuum chamber maintaining it at a temperature lower than its melting point, but sufficiently high for enabling said diffusion.
