ABSTRACT
This chapter discusses the compositions and mechanical properties of cast aluminium bronzes to CEN (European) specifications, together with their former British designations and nearest American (ASTM) equivalents. Cast aluminium bronzes may be grouped into three categories: High strength alloys, Medium strength alloys, and Non-magnetic alloys. The most widely used is the high strength alloy, CuAl10Fe5Ni5 which, in addition to high strength, has excellent corrosion/erosion resisting properties and impact values. The medium strength alloy CuAl9-C is used only in die casting and centrifugal casting where the chilling effect of the mould enhances the mechanical properties. The mechanical properties of cast aluminium bronzes can vary considerably with variations in cooling rate from the solidification point to room temperature. The chapter shows the effect of a range of operating temperatures on the mechanical properties of the two most common cast alloys, CuAl9Fe2 and CuAl10Fe5Ni5.
