FIELD: metallurgy.
SUBSTANCE: invention relates to alloys on base of aluminium designed for utilisation as electro-conductors continuously operating at temperature of 250-350°C under conditions requiring both hardness and electric conductivity. Alloy on base of aluminium contains the following ratio of components wt %: iron 0.15-0.70, aluminium oxide 0.1-1.0, at least one metal chosen from group of rare earth metals 5.0-20.0, beryllium 0.0003-0.0009, aluminium - the rest.
EFFECT: alloy possesses stable physic-mechanical properties at maintaining electric conductivity.
