YAXUN Solder Wire 0.8mm Sn63-Pb37

The YAXUN 0.8mm solder wire is well suited for general and mid-scale repair work that needs a larger amount of solder delivered quickly, such as soldering wires, connectors, and larger joints in circuits and electrical devices.

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 43g spool, suited for repeated use in workshops and general electrical maintenance work.
