An aluminium alloy conductor wire consists of between 97.25 and 99.4 (preferably 98.05 to 99.2) weight percent aluminium; between 0.3 and 1.0 (preferably 0.45 to 0.6) weight percent iron; between 0.22 and 0.7 (preferably 0.225 to 0.3) weight percent silicon, the ratio of Fe:Si being at least 4:3 and preferably at least 2:1; between 0.08 and 1.0 (preferably 0.2 to 0.5) weight percent copper; and trace quantities of conventional impurities. The conductor wire is especially suitable for use as a conductor of a telecommunication cable or as a component element of an overhead electric conductor.

Aluminium alloy conductor wire

A conductor wire is composed of an aluminium alloy consisting of between 98.0 and 99.5 weight percent aluminium; between 0.3 and 1.0, preferably 0.4 to 0.6, weight percent iron; between 0.16 and 1.2, preferably 0.3 to 1.0, weight percent silicon; and trace quantities of conventional impurities. The conductor wire has a higher tensile strength than wires of known aluminium alloys which contain similar quantities of iron and is especially suitable for use in telecommunication cables, wiring cables and overhead conductors. The conductor wire may have a cladding of copper or copper alloy.
