Home improvement solder for electrical soldering promising low-melting, smooth-flow joints. TOWOT Lead-Free Solder Wire suits DIYers and repair technicians who need dependable, lead-free solder for circuit boards and small appliance fixes. Will it deliver clean wetting and strong bonds on delicate components?
⚡ At a Glance
- • Soldering Performance: Low melting range and rosin core flux enable rapid wetting and flow
- • Best for: Circuit board repair, TV and radio fixes, DIY electronics and home appliances
- • Not ideal for: Heavy plumbing work or applications that explicitly require leaded solder
Lead-free alloy composed of 99.3% tin and 0.7% copper with a 2.0% rosin core flux. Melting point is specified at 217–222 ℃, supplied as 0.8 mm diameter wire, net 20 g.
Strong Metallurgical Bonds – With 99.3% Tin and 0.7% Copper Alloy
High tin content lowers the melting range and forms reliable intermetallic connections with copper pads, while the small copper fraction increases mechanical strength. The alloy composition supports rapid alloying between solder and component leads.
Durable joints that withstand handling and vibration, suitable for electronics repair and small appliance work.
Fast, Smooth Wetting – With 2.0% Rosin Core Flux
Rosin core flux cleans oxides from metal surfaces during heating, allowing molten solder to flow and bond quickly. A 2.0% flux content provides a balance between cleaning action and residue control.
Quicker soldering sessions with fewer cold joints and less post-solder cleaning on circuit boards.
Precise Application on Small Parts – With 0.8mm Diameter Wire
Thin wire diameter permits controlled solder deposit and fine solder feed for small pads and through-hole pins. Narrow gauge reduces the risk of excess solder bridging adjacent pads.
Easier to manage tiny joints and fine-pitch components without over-supplying solder.
