The properties and structure of a conductor wire made of aluminum with 0.1–0.3% Zr, 0.4–3.3% Ce, and 0.1–1.0% Fe, fabricatedby the method of ingotless rolling-extrusion (IRE) proposed by the authors, followed by drawing and intermediateannealing presented. Replacement of a part of Zr with Ce, Fe and the application of the IRE method provide the necessaryproperties of the wire by reducing the cost of manufacturing the alloy and the number of technological operations. To obtaina supersaturated Zr α(Al) solid solution after IRE without the formation of primary Al3Zrintermetallic phases to ensureuniform distribution of Al4(Ce, La), Al(Ce, La)Fe and AlFeSi phases, it is necessary to introduce an alloy into the meltat a temperature of 820–850 °C, and deformation during IRE with elongation coefficient 4.4–14.3 ensures the strength ofextruded rods 140–190 MPa with elongation to failure 25–30%. IRE, drawing of rods with combinations of Zr, Ce, Fe, andannealing on the properties of the wire has been studied. Annealing at 350 °C, 40 h–450 °C, 20 h after IRE, drawing, providesthe electrical resistance of the wire 0.0294 Ω mm2/m, strength 174 MPa and elongation to failure 1.5–2% with reduced Zrcontent to 0.10% by adding 0.6% Ce and 0.7% Fe. Aluminum alloys Al–3.3Ce–0.1Fe, Al–0.3Zr–0.2Fe, Al–0.20Zr–1.0Fe,Al–0.10Zr–0.60Ce–0.70Fe and flow charts for the production of conductor wire recommended. Wires meet the requirementsof ASTM B941-16 and IEC 62004-07. The research was supported by a grant from the Russian Science Foundation No. 22-79-00108, https:// rscf. ru/ proje ct/ 22- 79- 00108/.
