ABSTRACT
Wrought aluminium bronze components begin life as a solid cast ingot, billet or slab which is then normally hot worked into a desired shape and section. Many forgemasters, rolling mill owners and extruders, who normally work in high strength materials, have acquired the know-how to work aluminium bronzes. Extruders who have experience in extruding tubes in high strength metals are able to extrude the high strength aluminium bronzes, even though the grip of the alloy on the mandrel is considerable. Single-phase alloys can be much more extensively cold-worked than duplex and multi-phase alloys and it is possible to produce thinner sections in them. Details of the fatigue strength of some single-phase alloys for various forms and tempers are given in and endurance limits in air and sea water in. The following are typical applications for single-phase aluminium bronzes: Duplex alloys Alloys with 8.0%–8.4% aluminium are effectively on the upper limit of the ductile single-phase alloy range.
