AFAIK only in specialised low-temp solder, like the one sold by Chip-Quik to desolder sensitive components.

That's Tin-Bismuth eutectic, forming a 99 C (a hair below boiling water) eutectic when mixed with lead.

Yeah, but that's not for desoldering. It's for things like soldering heat sinks to flip-chip dies, or hermetic sealing cans for sensitive components.

I'm not surprised by them selling indium solder wire, but they offer all kinds of solder under that brand.
