Spool of 0.8 mm 63/37 tin-lead rosin-core solder wire 50 g

Solder Wire 63/37 0.8mm 50g

SKU CH-ATV1-YGVK9

63/37 tin-lead rosin-core solder wire, 0.8 mm diameter on a 50 g spool, melts at 183 °C with 2.2 % no-wash flux for clean electrical joints

  • Low 183 °C melting point flows smoothly for fast, strong joints
  • 63/37 tin-lead alloy with 2.2 % flux gives superior wetting and flow
  • No-wash rosin core leaves no residue for clean, reliable connections
  • 8 mm diameter on a 50 g spool suits fine electronic work
  • Suitable for electronics, phones, computers, appliances, toys and crafts

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.

Questions about this item

At what temperature does the 63/37 alloy in this 0.8 mm wire start to melt?

The 63/37 tin-lead alloy melts at 183 °C (361 °F), so the iron only needs to reach that point for the solder to flow.

Does the 2.2 % rosin flux core produce noticeable fumes or residue during long soldering sessions?

The no-wash rosin core is designed for low residue and minimal fumes, keeping the work area cleaner during extended use.

Besides a soldering iron, what else is required to use this 50 g spool of 0.8 mm wire?

Only a soldering iron capable of reaching 183 °C is needed; the flux is already inside the wire so no separate flux or cleaner is required.
