Thick 1mm 63/37 tin-lead solder with a rosin core, meant for through-hole pads, connectors, wire splices, and other joints that drink more solder. Thicker wire means fewer feed strokes on big pads.
63/37 is eutectic: one melting temperature, no mushy phase, so joints set fast and crisp.
Specs
| Alloy | 63/37 tin-lead (eutectic) |
| Flux core | Rosin |
| Wire diameter | 1mm |
| Melting point | Approx. 183°C |
| Weight | 50g (gross) |
For fine SMD work grab the 0.3mm to 0.5mm versions instead; this one shines on bigger joints.
