Post on the SWAGING forum here. IF You have enough of it...someone there may want it anyway.

Are you sure it's not "sb"? That would be antimony. If it's "sn", that's tin.

Sb is the chemical symbol for antimony. They are just making a fancy
"B" in my reading of it.

Hard for me to imagine home swaging lead with 4.5% antimony. Maybe it was intended for use in automated power swaging.
