Ecological ammunition

Abstract

The present invention relates to a composite material for the production of ecological ammunition characterized in that it comprises a) a metal matrix formed by a zinc and bismuth alloy, zinc and aluminum alloy, tin and bismuth alloy or zinc and tin alloy and a metal selected from aluminum, bismuth and the combination thereof and b) reinforcing metal particles distributed therein selected from wolframium, ferro-wolframium, ferro-wolframium carbides, wolframium carbides, wolframium oxides and ferro-wolframium oxides, subjected to oxidation before being added to the metal matrix.
