1. A process for forming electrical conductors of aluminum-iron alloy consisting of by weight from 0.5 to 5% of iron, from 0.02 to 0.2% of silicon, the remainder being aluminum and impurities, comprising granulating the Al-Fe alloy into particles of an acicular shape having a diameter of between about 50 and 1000 μ

  • m and a length of between about 1 and 10 mm, introducing said shaped divided alloy into a container of an extrusion press, preheating said container at a temperature between about 300° and

    600°

    C., and extruding said alloy at a press extrusion ratio at least equal to about 5 to about 10 to provide conductors having a very highly fibered structure in the longitudinal direction and in which are present monoclinic Al3 Fe particles.
