Solder Wire 63/37 0.8mm 50g

Solder Wire 63/37 0.8 mm 50 g

This rosin-core solder wire uses a 63/37 tin-lead alloy with 2.2 % flux for reliable electrical connections. The low melting point of 183 °C allows fast, smooth flow and strong joints. It suits hobbyists, technicians and anyone repairing circuit boards, phones, computers or small appliances. The 50 g spool provides enough material for many small jobs without excess waste.

No-clean flux and diameter choice

The 2.2 % no-wash flux leaves no residue, so boards do not need cleaning after soldering. The 0.8 mm diameter works well for through-hole pins, fine-pitch components and general wiring. Thinner 0.6 mm or thicker 1.0 mm wires are available for different joint sizes. The wire feeds easily from the spool into any standard hand-held iron.

Capacity and limits

The 50 g spool handles dozens of typical repair joints and small prototype builds. It runs out quickly on large harnesses, heavy gauge wire or production runs where 100 g or larger spools are more practical. The 63/37 alloy is not suited for lead-free requirements or high-temperature applications above its melting point.
