Alloy and flux make-up

This solder wire uses a 63/37 tin-lead alloy with a 1.8% rosin flux core. The eutectic composition melts at a single temperature, giving consistent flow for electrical joints. It is supplied on a 50 g spool at a diameter of 0.6 mm.

Suited to fine board work; not for heavy cable

The thin diameter makes it ideal for circuit-board repair, hobby electronics and small appliance soldering where precision matters. Users joining thick wires, large terminals or plumbing-scale copper will find the wire too small and the flux volume insufficient for those joints.

Capacity and headroom

A 50 g reel provides enough material for dozens of small through-hole or surface-mount connections on typical boards. Extended production runs or high-volume assembly will consume the spool quickly, requiring additional reels to maintain workflow.
