Sn42Bi58 Tin/ Bismuth Not so good at all for soldering
This stuff contains bismuth a metal with some unique properties almost none of which make it a good solder. The low melting point is a good start but that is all there is.
Bismuth is known for being brittle and a semi conductor when used in thin layers it also has the worst thermal conductivity and a low electric conductivity.
This means it will crack, work as a resistor not a conductor. Making solder out if it is just stupid. I tried two formulations of this product and both are just no good at all. Read about Bismuth online.
