Material This soldering wire is made of high-purity tin, contains no harmful metals, and is safe for people and the environment. It offers high strength and hardness to help improve the stability and reliability of solder joints and ensure long-term durability of the soldered structure. What you get Package includes 2 rolls of solder. Each roll measures 2.18 x 4.4 cm (0.86 x 1.73 in). The solder diameter is 0.8 mm (0.03 in). Melting point is 220-227 C, providing a low melting point and fast soldering. Sufficient length on each roll meets daily use and replacement needs. Excellent soldering properties The solder wire has excellent fluidity and fully melts and flows during the soldering process, yielding a good fit and high-quality welds. It fills the smallest gaps to ensure weld integrity and robustness, making it suitable for a wide range of soldering tasks. Easy to use The wire is soft and pliable, easy to handle by hand. You can easily shape and lengthen or shorten it to fit different soldering requirements. The operation is straightforward and does not require complex equipment or techniques, reducing difficulty and cost. Use scenarios - Soldering electronic circuit boards and components during assembly or repair. - Electrical wiring and harness repairs in consumer electronics and small appliances. - DIY hobby projects, model building, and other precision soldering tasks that benefit from good flow and gap filling.
