Are there places that use SnBi for production devices? I know Bismuth alloys are used to desolder stuff (and they work amazingly well for that), but the general rule is that you should clean it up before soldering something new. (And keep it for later use, because it isn't exactly cheap.) It's a heavy metal and reading https://en.wikipedia.org/wiki/Bismuth#Toxicology_and_ecotoxicology https://en.wikipedia.org/wiki/Bismuth#Toxicology_and_ecotoxi... it looks like we don't know a lot about it yet, but to me it looks extremely unlikely to be better for the environment than SnAgCu. Also Bismuth appears to be rare: https://en.wikipedia.org/wiki/Abundances_of_the_elements_(data_page) https://en.wikipedia.org/wiki/Abundances_of_the_elements_(da... Rarer than palladium. All the even rarer elements are generally known to be rare and/or precious, or radioactive elements that normal people would never come across.
