There is a difference between lead and lead-free materials

Material: Lead

Description: The surface of the solder wire with lead is very bright, and the solder wire is used for the welding of similar products with lead. The melting point is relatively low, about 183 degrees, so the damage to electronic products is less, and the solder wire with lead leaves black traces, improving the activity of the tin wire process, depending on the use of the product, matching the process components.

Material: Lead-free

Description: Lead-free solder wire also known as environmental protection tin wire has good wettability, conductivity, thermal conductivity, easy to tin, lead-free tin wire for export to Europe and the United States and other countries of the product welding, it used tools and components must be lead-free, lead-free traces of light yellow, because lead-free generally called copper metal.

Advantages of lead solder wire over lead-free solder wire

Lead solder wire winding is very neat, never knotted, easy to operate when welding, and high efficiency, flux distribution is uniform, no broken flux phenomenon in the core. Lead-free solder after melting slag less than ordinary solder, has excellent oxidation resistance, low melting viscosity, lead solder is generally used in electronics, electrical, toy industry, the use of canning, automotive manufacturing industry is not high requirements of welding place, lead-free solder is used in electronics industry, manufacturing, maintenance industry, so from the price and performance, I will recommend this lead solder wire
