Lead-Free Solder Wire: Lead-free solder wire with rosin core; Our solder wire has good solderability in terms of both electrical conductivity and thermal conductivity; The solder wire is made of high-quality materials, free from impurities, safe and reliable, and can be used for a long time. Lower Melting Point: The melting point of the solder wire is 227℃. Flexible and thin wire, perfect for home soldering workers. With the solder wire reel, soldering can be done quickly. Weight and diameter, the diameter of this lead-free solder wire is 0.8 mm; net weight: 20g; Sn 99.3% Cu 0.7%; Flux content: 2.2%. Lead-Free Tin: Lead solder, although very simple and convenient to use compared to lead-free, is terribly harmful to health and the environment. Avoid lead-related health problems and abandon old habits. Very Economical: Using solder in a reel is much more economical for you than buying in small containers. In addition, you don't need to buy extra flux or rosin for the set, as the inside of this box is already filled with them. Wide Range of Uses: Tin to lead-free solder on a convenient extraction reel can be used for many repairs. Even if you are not a professional electrician working in service, it will be useful for: permanent soldering of electrical wires or cables, repair of toys, headphones, TVs, speakers, microphones, motherboards, SMB components and much more.
