V. Eutectic research.—No. 1. The alloys of lead and tin

Thus, while Roberts-Austen gives the composition of the eutectic alloy as approximately 31 per cent, of lead and 69 per cent, of tin, the present investigation shows the composition of this alloy to be very nearly 37 per cent, of lead and 63 per cent, of tin.

Lead-Free and Leaded Solder Compositions JOHNSON MFG. CO.

Our most popular solder within the binary (2-element) tin-silver family of solders is Johnson's #460, which is a eutectic alloy that melts at 430 degrees F (221 C). To our knowledge, this is the only alloy that is acceptable for use when soldering food handling equipment.
