52In/48Sn solder has a melting point 118C, and can be reflow processed at temperature down to around 165-170C. The material is very soft, very low in shear strength. It is relatively ductile, can be stretched to about 2-3X of Sn63 in elongation. Among all of Pb-free alloy options, this one is the lowest in mp. It is mainly used in some nitche applications.
