Rosin-Cored Lead-Free Low-Temperature Solder Wire (Sn42Bi58)

Rosin-Cored Lead-Free Low-Temperature Solder Wire (Sn42Bi58) is an eco-friendly soldering material engineered for precision electronic assembly tasks. This Sn42Bi58 Rosin-Cored Lead-Free Low-Temperature Solder Wire features a high-purity tin-bismuth alloy formula with a low melting point of around 138℃, minimizing thermal damage to heat-sensitive components such as lithium battery cells, nickel strips and battery brackets during the soldering process. Infused with high-activity rosin flux, the Lead-Free Low-Temperature Rosin-Cored Solder Wire Sn42Bi58 eliminates the need for additional flux, enabling fast tin wetting, smooth and bright solder joints, and effectively preventing common issues like cold solder joints and false soldering. As a lead-free and environmentally compliant option, Rosin-Cored Lead-Free Low-Temperature Solder Wire (Sn42Bi58) contains no harmful lead content, meeting the strictest industrial and DIY production standards.
