METAL IN MOTOR CARS
The discovci’y of new metals and new alloys in the last quarter of a century has enabled motor car manufacturers to build cars which would have weighed twice as much if constructed of materials available in 1910. Alloyed steel began to be used by car makers about 1907 and quickly gained recognition as a material for production of better, lighter-in-weight automobiles. To-day one manufacturer uses 50 kinds of steel, each treated so that it may perform a certain function in the finished car. Typical of the modern motor cars is an American car which contains about 19001 b of steel, 3501 b of cast grey iron, and 351 b of cast malleable iron. This same car has 701 bof rubber, 501 b of glass, slightly more than 301 b each of copper and lead, about 151 b of zinc, and the same of manganese. Aluminium, tin, chromium.-anti-mony, nickel, and cadmium -are used in smaller amounts.
