A low temperature, lead-free, cadmium-free solder for joining metals, primarily copper tube or brass pipe and fittings. The solder composition, being free of lead and other known toxic metals, has a composition range of 0.5-4.0% antimony, 0.5-4.0% zinc, 0.5-2.0% silver and 90.0-98.5% tin, is especially adaptable for plumbing applications where solder joints are exposed to potable water.

Lead-free Solder Composition PCB

Lead-free solder materials as the name suggest do not have any lead in their composition. Originally when solder materials and solder paste were developed they almost always used lead. However, lead is a harmful/poisonous material and thus in 2006 the use of lead based soldering materials were prohibited by the RoHS directive (2002/95/EC).
