Did you know?
WebBismuth stood out as a key to whisker mitigation. All the alloys containing bismuth were low whisker producers, presumably because it refines the grain structure of the metal. But, like silver, there is a threshold where … WebBismuth (Bi) is being used more and more as a replacement for lead in solder alloys because it is non-toxic. Although the melting temperature of pure bismuth is 271°C, the addition of bismuth will lower the melting temperature of most metals it is alloyed with. Bismuth compounds are also widely used in medical and cosmetic applications ...
WebDec 1, 2006 · The thermodynamics of Bi–In–Sn lead-free solder alloys has been studied by two different experimental techniques: torsion–effusion and differential scanning calorimetry. The results show that this ternary system at fixed Bi composition, , and 565 K behaves as a non-ideal system with exothermic passing through a minimum at and .

WebNov 11, 2011 · ContactEric Bastow. Intermetallics are a necessary evil in the metal-to-metal bonding world, which definitely includes soldering. There are two basic ways that metal will "chemically" bond to another metal: 1) solid solution 2) intermetallic. We will focus just on intermetallics for the moment as that is the most pertinent to the soldering world. WebBismuth has also been used in solders. The fact that bismuth and many of its alloys expand slightly when they solidify make them ideal for this purpose. 1. Many bismuth alloys have low melting points and are …
