Lead-free solder wire: Lead-free solder wire with a rosin core; Our solder has good soldering properties in terms of both electrical and thermal conductivity; The solder wire is made of high-quality materials, is free of impurities, safe and reliable, and can be used for a long time. Lower melting point: The melting point of the solder wire is 227°C. Flexible, thin wire, ideal for home soldering. Soldering can be carried out quickly with the solder wire spool. Weight and diameter: The diameter of this lead-free solder wire is 0.8 mm; Net weight: 20 g; Sn 99.3% - Cu 0.7%; Flux content: 2.2%. Lead-free solder: Lead solder, although very easy and convenient to use compared to lead-free solder, is extremely harmful to health and the environment. Avoid lead health problems and give up old habits. Highly economical: Using solder in a spool is much more economical than buying it in small containers. You also don't need to buy additional flux or rosin, as the inside of this tin is already filled with them. Wide range of applications: Lead-free solder on a convenient spool can be used for many repairs. Even if you're not a professional electronics technician, it will be useful for: permanently soldering electrical wires or cables, repairing children's toys, headphones, televisions, speakers, microphones, motherboards, SMB components, and much more.
