ABSTRACT
Aluminium bronzes are copper–base alloys in which aluminium up to 14% is the main alloying element. The name 'Aluminium-Bronze', initially given to this range of alloys, is really a misnomer, since bronzes are alloys of copper and tin. In order to obtain a good combination of strength and elongation in this type of complex alloys, together with good corrosion resistance and workability, the aluminium content must be a compromise, and controlled to close limits. The trend is very similar to that of the binary copper–aluminium alloys with a slight increase in tensile strength and reduction in elongation. The alloys containing approximately 5% each of iron and nickel are the most popular cast and wrought aluminium bronzes because of their combination of high strength and excellent corrosion resistance. The effect on mechanical properties of varying the iron content in the presence of 5% nickel for a range of aluminium contents, where it can be seen that this effect is significant.
