It was reported in the 1st report that the tensile properties of lead were improved by addition of silicon, but the results were not satisfactory. So, the author tried to improve the tensile properties by addition of silicon to lead-antimony alloys. This time, good results were obtained as follows: A remarkable improvement of tensile properties was found in the solid solubility range on the lead side of lead-antimony-silicon alloys, and the solid-solution treated alloys showed better results than as-cast and extruded alloys. The tensile strength was the largest in solid-solution treated lead-antimony-silicon alloy containing 3% antimony and 0.035% silicon and its elongation and reduction of area were generally better than in as-cast and extruded alloys. These results suggest that the solid-solubility range on the lead side of lead-antimony-silicon alloys is wider extended than that of lead-antimony alloys.
