About thirteen years ago I acquired just over fifty pounds of Babbitt in its' original ingot form. I had spent quite a bit of time, off and on, searching the internet to determine the composition of these ingots, but to no avail. The only luck I had was finding information on the Magnolia Antifriction metal.
"One of these days. I'll haul these ingots down to the junk yard and have them shot with an XRF gun.", I thought.
Well, this past Tuesday was the day. I had ten ingots shot and the results below indicate the major elements, rounded to the nearest one-half of one per cent, contained in each alloy.

Magnolia Anti-Friction Metal is a primarily lead based material but with the addition of graphite for to make it somewhat self lubricating, consisting of approximately 80% Lead (Pb), 15% Antimony (Sb) and 5% Tin (Sn), making it very similar to a ASTM B-23 Grade 8 Babbitt.
Pouring temperature for Magnolia Anti-Friction Metal is 750-825 degrees F

Mystery Metal
I don't know how this ingot found its' way onto my lead rack. It looks like a over-stuffed Sky Bar. There are no manufacturers' markings of any kind. Somebody had scratched "LEAD" onto the ingot, but seeing as how light the bar was for its' size in contrast to most lead alloys and the extreme hardness, I had my doubts. I always thought it may be a zinc alloy. But, I hung onto it and took it along for the ride on Tuesday. I'm happy I did.
