Below is a list of the most common bismuth alloys. A listing of many others is available in our Solder Alloy Selector Guide.
|42||46Bi 34Sn 20Pb||96°C||96°C||Low temperature eutectic solder. Can be used on the same metallizations as SnPb solders. Lowest temperature alloy available as a solder paste.|
|281||58Bi 42Sn||138°C||138°C||Eutectic Pb-Free version. Low melting temperature that is good for step soldering applications.|
|282||57Bi 42Sn 1Ag||140°C||139°C||More malleable and ductile than #281.|
|97||43Sn 43Pb 14Bi||163°C||144°C||Good general purpose step soldering alloy.|
|281-338||60Sn 40Bi||170°C||138°C||General purpose Pb-Free alloy with good physical properties.|
