Lead-free solder wire: Lead-free solder wire with rosin core; Our solder 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, thin wire, great for home soldering workers. With the soldering wire spool, soldering can be carried out quickly. Weight and diameter, The diameter of this lead-free soldering 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 easy and convenient to use compared to lead-free, is terribly harmful to health and the environment. Avoid lead health problems and give up old habits. Very Economical: Using solder in a roll is much more economical for you than buying it in small containers. Also, you don't need to purchase any additional flux or rosin with the set as the inside of this can is already filled with it. Wide Application: Lead-free solder on a handy peel-off spool can be used for many repairs. Even if you are not a professional electronics technician working in service, it will be useful for: permanent soldering of electrical wires or cables, repairing children's toys, headphones, TVs, speakers, microphones, motherboards, SMB components and much more., Manufacturer: Dolaso
