Sn99%-Ag0.3%-Cu0.7% electric solder coil with flux Lead-free solder wire <ul class="a-un0rdered-list a-vertical a-spacing-mini"> <li class="a-spacing-mini"><span class="a-list-item">Rosin core solder wire is made of Sn99, Ag0.3, Cu0.7, and has a flux content of 2.0%, making it more economical and environmentally friendly. </span></li> <li class="a-spacing-mini"><span class="a-list-item">The wire has a gross weight of 100g (0.22lb), a diameter of 1.0mm (0.039 inches), and a melting point of 217°C/422.6°F. The low melting point is safer and allows for faster soldering, reducing thermal shock to components. </span></li> <li class="a-spacing-mini"><span class="a-list-item">This tin solder wire is safer than lead solder wire, and the solder wire colors are different. Lead-free solder wire has a brighter color, while lead solder wire is dark gray. </span></li> <li class="a-spacing-mini"><span class="a-list-item">This lead-free silver solder wire has good fluidity and heats evenly. It is easy to use and is the solder wire that achieves the best soldering results. </span></li> <li class="a-spacing-mini"><span class="a-list-item">This lead-free solder wire is widely used for soldering and repair of IC products, PCBs, electronic products, as well as for fine soldering work such as hardware, or for DIY enthusiasts. </span></li> <li class="a-spacing-mini"></li> </ul>
