60/40 Solder Wire 4 PCS Rosin Core 0.8mm 12g 1mm 15g

Solder wire kit for electronics repair

This set contains four spools of 60/40 tin-lead alloy wire with rosin cores. Two spools measure 0.8 mm diameter at 12 grams each and two measure 1 mm diameter at 15 grams each. The 1.8 percent flux content promotes clean joints on circuit boards, stereo equipment, radios and headset wiring. It suits hobbyists assembling stained glass pieces or fixing toys and small appliances.

Melting range and flux limits

The alloy melts between 183 °C and 266 °C (361 °F to 511 °F), giving a broad window for hand-soldering without overheating sensitive parts. Rosin flux activates in that same range so residue stays minimal, but it cannot clean heavily oxidised surfaces or replace dedicated flux for high-reliability work. Lead content requires ventilation and thorough hand washing after use; the material is not intended for potable-water plumbing or food-contact applications.

Spool handling and storage

Each lightweight spool fits easily in a tool drawer or soldering station caddy. The rosin core remains stable at room temperature but should be kept sealed when not in use to prevent flux degradation. Wire stiffness at 0.8 mm and 1 mm diameters allows precise feeding through fine tips, though very dense multi-layer boards may demand thinner gauges not included here.
