Solder wire for electronics repair

This 63-37 tin-lead alloy wire contains a rosin core and 1.8 % flux. Each spool weighs 50 g and measures 0.6 mm in diameter. The pack supplies 12 spools for repeated circuit-board, cable and small-device work.

Build integration: hand-soldering consumable

The wire feeds directly from the 55 mm by 30 mm reel into a soldering iron tip. No external flux, power supply or specialised station is required. It frees the user from separate flux application and suits field repairs where bench equipment is unavailable.

Thermal behaviour and power profile

Melting occurs at 183 °C or 361 °F, allowing joints to form quickly with moderate iron temperatures. The low melting point reduces thermal stress on components and keeps fumes manageable. Lead content demands hand washing after use per Proposition 65.

Questions about this item

How long does a single 50 g spool last during continuous soldering?

Each spool holds 50 g of 0.6 mm wire; duration depends on joint size and operator speed.

Does the rosin flux produce noticeable fumes or heat during all-day use?

Flux content is 1.8 %; the alloy melts at 183 °C so the iron, not the wire, determines tip temperature and fume volume.

What diameter soldering-iron tip works with the 0.6 mm wire?

The wire is 0.6 mm (0.0236 in); choose a tip that matches or slightly exceeds that width for best heat transfer.
