ABSTRACT:
A metallic material, particularly useful for electrical contacts, comprises a matrix metal, for example silver or copper, with additives embedded therein in powder form. However, while being in powder form the additives are arranged in elongate fiber like lengths preferably parallel fiber like lengths. A method of producing such a distribution is to fill a tube of the matrix metal with the powder and draw it out to wire thickness, bundle a number of such wires together and fuse the outer coverings to form a continuous matrix with embedded fiber like lengths of powder.
