YCS Original Solder Wire 0.6mm Sn63-Pb37

The YCS Original Solder Wire in 0.6mm diameter is a reliable choice for general electrical and electronics work, suited for soldering wires, connectors, and mid-scale repair jobs that need a good amount of solder delivered quickly.

Its formula is Sn63/Pb37 alloy (63% tin, 37% lead), with a melting point of 183°C — a eutectic alloy that transitions directly from liquid to solid, giving clean, stable joints on the first pass. It contains 1.2% rosin content, helping remove surface oxidation and improve adhesion without needing extra cleanup afterward.

It comes on a spool with a 55.2mm outer diameter and a total weight of 52g, suited for repeated use in workshops or home electrical and electronics maintenance.
