A method by which the distribution of the particulates of a plurality of metal powders, the metals of each powder being of different densities, may be uniformly disbursed within a dry mixture of the powders and by which this uniform dispersion of the different density powders can be sustained through subsequent handling and/or storage of the mixture. In accordance with one aspect of the present invention, a quantity of each of a plurality of metal powders is admixed with a dry stabilizing non-metal powder. One particularly useful non-metal powder is a micronized polymer, preferably micronized polyethylene.
