    Tin based babbitts are considered superior to lead based alloys in as much as they pour more readily and provide an excellent bond between the shell and lining. They are customarily used for high speed, high temperature load bearings. Lead based babbitts are more economical and used for low speed, uniform speed and moderate pressure as in line shafting, electric motors and general machinery.

    In tin lead solder, the mixture has a lower melting point than either lead or tin alone, and the melting point varies depending on the portions. The mixture that yields the lowest melting point is called eutectic. This is also the only mix where all the constituents melt and freeze at the same temperature.
