Highlighted here is a lead-free solder bar for commercial use.
It may contain tin, copper, silver, bismuth, indium, zinc, antimony, and traces of other metals. Most lead-free replacements for conventional Sn60/Pb40 and Sn63/Pb37 soldering have melting points from 5 to 20°C or higher, though solder bars with much lower melting points are available.
This lead free solder bar is suitable for wave soldering and manual soldering. It has low melting point, low using temperature, strong anti-oxidation property, good solder ability and thermal fatigue resistance. The surface of solder joints is bright and allows soldering with a glazed surface.
