Anybody ever do any casting with # 13 Babbitt? This stuff goes by the name of "White Metal Bearing Alloy (Lead Based)". Or any other number babbitt for that matter. I got several hundred pounds at an auction, looked it up on the web and got some numbers: Sn (Tin) = 6% Sb (Antimony) = 10% Pb(lead) = 83% As (Arsenic)= .25% and some impurities less than .1%. I figured the high tin content would be good for mold fillout, the antimony, lead and arsenic are close to wheelweights. Any Comments?
