Description
|
Lead-free solder wire is made of lead-free pure tin, pure copper, pure silver and other alloys in proportion to high-grade anti-oxidation alloys. After high temperature dissolution, refining, decontamination, and re-making into tin cylinders, the rosin medicament is poured into the cylinder by hydraulic press. It is made by drawing according to different wire diameter requirements. The alloy composition can be divided into pure tin lead-free solder wire, tin-copper lead-free solder wire, tin-silver-copper lead-free solder wire, and the flux is uniformly poured into the middle part of the solder alloy through an oil press. |
