The effect of iron on aluminium bronze.

Aluminum bronzes comprise that group of copper-aluminum alloys containing from very small amounts up to approximately l6 per cent aluminum by weight. Appreciable quantities of iron, manganese, nickel, and other elements are frequently added which results in complex alloys where more than one of the above elements are added to the bronze.Considered in the light of properties obtainable by heat treatment these alloys represent some of the most versatile non-ferrous alloys in wide use today. They combine the property of great strength, which can be altered as required by proper heat treatment, with excellent corrosion resistance. The alloys can be subjected to heat treatments similar to those used for the heat treating of steel. By means of suitable treatments, it is possible to obtain increased strength, good ductility and other desirable qualities. The many good features of this series of alloys make them useful for a large variety of modern industrial application, particularly in the marine, automative, and chemical industries.[...
