Welding wire (tin wire) has different kinds of additives. The auxiliary part is to improve the auxiliary heat conduction of the welding wire in the welding process, remove oxidation, reduce the surface tension of the welded material, remove the oil stain on the surface of the welded material and increase the welding area. Solder wire is a kind of tin alloy wire with a certain length and diameter, which can be used with electric soldering iron in the welding of electronic components.

Specification classification of tin wire: according to different situations in tin wire, how many classification methods are there? :lxhsxcj
According to metal alloy materials, it can be divided into tin-lead alloy solder wire, pure tin solder wire, tin-copper alloy solder wire, tin-silver-copper alloy solder wire, tin-bismuth alloy solder wire, tin-nickel alloy solder wire and solder wire with special tin-containing alloy materials.
According to the chemical composition of solder wire additives, it can be divided into solder wire with rosin core, solder wire without cleaning, solder wire with solid core, solder wire with heavy weight, solder wire with single core, solder wire with three cores, solder wire with water solubility, aluminum solder wire and stainless steel solder wire.
According to the melting temperature, it can be divided into low temperature solder wire, normal temperature solder wire and high temperature solder wire.
