Type Metal
the alloy of lead and antimony used in casting printers' types, the usual proportions being one part of antimony to three of lead, but a superior and harder kind of type is sometimes made by alloying two parts of lead with one of antimony and one of tin. Both these alloys take a sharp impression from the mold or matrix, owing to their expansion on solidification, and they are hard enough to stand the work of the press, without being brittle or liable to fracture.
