Sumwitum 0.8mm Lead Free Solder Wire - Sn99.3 Cu0.7 Rosin Core

Upgrade your electronic repairs with Sumwitum Lead Free Solder Wire. This high-quality Sn99.3 Cu0.7 alloy is specifically designed for electrical and thermal conductivity, making it an ideal choice for DIY projects and professional component repairs. The 0.8mm diameter provides precise control for delicate work on circuit boards and small electronic parts. Each spool features a built-in rosin flux core (1.8-2%) to improve fluidity and ensure strong, reliable solder joints. This flux helps reduce welding slag, resulting in bright and clean connections every time. Because the solder flows smoothly, you can avoid the extra step of cleaning after welding, saving you time and effort during complex repairs. Designed for efficiency, this solder wire has a melting point range of 185C to 190C (365F to 374F). The compact 45g net weight packaging is easy to store or carry in a tool kit, making it perfect for hobbyists and technicians who need a reliable, safe, and impurity-free soldering solution for their workbench.
