Lead-free Tin-Zinc alloy contains Manganese in the amount of about 0.001-0.9 wt. %. The alloy is suitable for use as a solder with commercially available fluxes. Various types of solders can be prepared from the alloy, like wire, cored wire, atomized powder, solder paste, thin sheet, ribbon foil, perform etc. The alloy has improved mechanical and electrical properties in comparison with conventional Tin-Lead alloys Sn9Zn and 63Sn37Pb.
