Delta Metal is a variety of brass containing 55 percent copper, 41 percent zinc and 4 percent various other metals. It was invented in the 19th century (patented in 1883 - 1884) by Dick and the original delta metal contained a small portion of iron. Delta metal is of a yellowish or golden colour, and in certain respects superior to malleable iron or steel. It may be rolled either hot or cold, drawn out into wire, is easily forged, and becomes very fluid when melted, so as to be easily cast into small articles, being also very suitable for artistic objects. It does not rust, and was much used for fittings and parts of machinery of various kinds, for ships' sheathings and screws, tools, etc and was used in Geneva for making watch cases in 1885.
