20140130698 | ECOLOGICAL AMMUNITION - 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. | 05-15-2014 |
20110017354 | MATERIALS FOR THE PRODUCTION OF ECOLOGICAL AMMUNITION AND OTHER APPLICATIONS - The present invention provides an ODS type material (Oxide dispersion strengthened or particle dispersion) which comprises an alloy metal matrix and a dispersion of strengthening particles distributed therein which provide the same with optimum density and deformability. Said metal matrix is constituted by an alloy of zinc and bismuth, of zinc and aluminium, of tin and bismuth, or of tin and zinc, the strengthening material being of tungsten or ferro tungsten, oxides of both, carbides of both, or derivatives of the same. Said new material can substitute for lead in the production of ecological ammunition, hooks for fishing, inertial counterweights in automobiles, X-rays and ionising radiation screens, golf sticks, water pipes and plumbing fittings, as well as in electrical and magnetic applications. The invention also provides an ecological ammunition manufactured from said composite material, such as, for example, pellets. | 01-27-2011 |
