Lead-Free Solder Wire

2.0mm Diameter | 100g Reel | Rosin Core 2.2% | RoHS Compliant

This Sn99.3/Cu0.7 (Tin-Copper) lead-free solder wire is engineered for specialized, high-current, and high-thermal-mass soldering applications. With a robust 2.0mm diameter, this wire is designed for rapid deposition, making it ideal for large-gauge wire tinning, busbar connections, and joining high-power components where standard 0.8mm or 1.0mm wire is insufficient. It is fully RoHS compliant, utilising a high-purity eutectic alloy that provides superior wetting and joint strength compared to cheaper, non-compliant alternatives.
