Lead-Free Solder Wire Sn99 Ag0.3 Cu0.7
This 50gram spool uses a Sn99-Ag0.3-Cu0.7 alloy with a 2% rosin core. The 0.8mm diameter wire melts at 217°C or 422.6°F and is intended for electrical soldering tasks. It suits hobbyists and technicians who need a lead-free option for circuit boards and general repairs.
Suited For Circuit Boards And Small Repairs
The thin 0.8mm gauge works well on dense boards, cables, radios and toys where precision matters. Builders who need larger joints, heavy-gauge wire or plumbing-scale solder should look at thicker diameters. Users who require leaded alloys for specific legacy processes will need a different composition.
Melting Point 217°C / 422.6°F
This single figure determines whether your iron and components can handle the joint. The alloy flows smoothly at this temperature with the included flux. If your equipment cannot reach or control this heat level, the wire will not perform as specified.

Questions about this item
What does the Sn99 Ag0.3 Cu0.7 alloy composition mean for melting point?
The Sn99 Ag0.3 Cu0.7 alloy melts at 217°C (422.6°F), a lower melting point that helps protect sensitive components during soldering.
Will the 0.8mm diameter wire fit my fine-pitch circuit board work?
At 0.8mm (0.0315 inch) diameter with 2% flux core, this wire suits general electrical soldering including circuit boards and small component leads.
How do I avoid cold joints when using this rosin-core solder wire?
Heat the joint — not the wire — until the solder flows smoothly; the 2% rosin core cleans oxidation but only works if the parts reach 217°C first.
