WebMost of these are Sn based solder where Sn is the main constituent along with one, two or even three other minor elements. If added in small amount, Bi can improve the wetting ability and reduce melting temperature of lead free solder alloys. It also increases strength of the bulk solder and inhibit the large Ag 3 Sn formation in the bulk solder. WebBismuth has one of the lowest thermal conductivities of pure elemental metals. It is fragile, highly diamagnetic and it has a magnetic susceptibility of −1.68×10 −5 mks. Bismuth is used as catalyst in the production of plastics and cosmetics, as an additive in steel alloys, and in electronics. It has a rhombohedral (Biα) structure, with ...
