Abstract

PURPOSE: To provide the titled grade enhancing agent made of alloy contg. a specified percentage each of Bi, Sb and Ag and enhancing the physical and mechanical characteristics of an Sn-Pb alloy when added to the alloy in a prescribed ratio.
CONSTITUTION: This grade enhancing agent is made of alloy consisting of 70± 10% Bi, 30±10% Sb and 0.6±10% Ag. For example, this alloy is manufactured by melting and mixing 69.6% Bi, 29.8% Sb and 0.6% Ag in a vacuum vessel, 0.5% this alloy is added to a melting vessel holding a 55%Sn-45%Pb alloy, and the alloys are mixed. The melting temp. of the resulting alloy is regulated to 183°C solidus line temp. and 196°C liquidus line temp., so the Sn-Pb alloy is made almost equal to a 57%Sn-43%Pb alloy in melting temp. Accordingly, by adding the alloy of this invention to an available Sn-Pb alloy, the mechanical and physical characteristics, this is, the grade of the Sn-Pb alloy can be enhanced.
