The aluminum alloy cable is produced through enabling the aluminum alloy to be subjected to the processes of melting, casting and rolling, so as to obtain aluminum alloy rods, then, carrying out drawing, stranding and softening, so as to form aluminum alloy conductor wire cores, and then, carrying out extruded insulation, cabling and extruded sheathing or armoring on the conductor wire cores. The Al-Fe-Cu-Mg-Zr series aluminum alloy for the cables for the coal mines, disclosed by the invention, has the characteristics of high strength, high conductivity, good bending property and the like; the aluminum alloy cable produced from the aluminum alloy can meet the requirements on the properties of the cable in the field of the coal mines.
