Antimony is a white metal which fuses at a low temperature and is readily vaporized, says the American Machinist. It is of a laminated or crystalline textile and is very brittle. It is used in several valuable alloys, but is not used in the pure state; its most important alloys are type-metal, britannia metal, pewter, and various anti-friction metals. Type metal consists essentially of lead and antimony, with, frequently, the addition of tin, nickel or copper in small quantities. Brittannia is a white-metal alloy much used for table-ware, and consists of antimony, with tin, copper and bismuth. A similar alloy, containing, however, a smaller percentage of antimony, is pewter. The antifriction alloys usually are known as babbitt metals. One of them consists of 30 parts of tin to 5 of antimony and 1 of bismuth, but, as is well known, various proportions are employed. Antimony has a hardening effect when added to lead; a small quantity of bismuth gives the alloy the property of expanding at the instant at which it solidifies, the result being a perfect cast from the mould.
