Tin is a metal that melts at less than 250°C, is very malleable (can be made rolls with it), is not easily oxidized, endures to corrosion and is relatively inexpensive. So it's perfect to weld in electronics. Br> br> Usually is presented in proportions mixed with 60-40% lead and a core of colophony resin, which improves the properties of the welding.
