Abstract: Tin-based alloys filled with steel shots or/and reinforced with short tin-coated steel fibers were prepared by melting the alloy phase and by mixing filler shots/fibers with the molten alloy in an air atmosphere with the addition of ammonium chloride. The content of steel shots ranges up to about 40 weight % and the fraction of tin-coated steel fibers ranges up to about 30 weight %. New reinforced composite alloys have a higher strength than unreinforced conventional alloys while keeping the melting temperature of new composites in the same range of unreinforced alloys.
