Babbitt Metal
To make this composition, melt copper 4; then add gradually tin 12, antimony 8, and a further addition of tin 12. When about 4 or 5 pounds of the final addition of tin has been added the heat may be reduced to a dull red, and the remainder added. Or, the copper, tin, and antimony may be melted first in separate crucibles; then poured together into one vessel and the final addition of tin introduced.
The above is a hardening. For lining take 1 pound of hardening and melt it along with 2 pounds of tin, which produces the lining metal for use. It will be seen that the resultant mixture contains: copper 4, tin 96, antimony 8. Banca-tin and the best quality of copper and antimony is to be employed when it is desired to make good antifriction metal. See ANTIFRICTION METALS; ALUMINUM.
