process for the manufacture of electrical conductors in aluminium - magnesium - silicon - empty rings, in particular for surface energy gietransportleidingen and shaped conductors.

摘要

The invention relates to improved electrical conductors of aluminum-based alloys containing from 0.15 to 0.35% of iron, from 0.30 to 0.70% of silicon, from 0.30 to 0.80% of magnesium, and up to 0.40% of copper. These conductors are obtained by drawing wire rod at a temperature of from 110 DEG to 180 DEG C, followed by artificial aging at a temperature in the range from 130 DEG to 240 DEG C. The invention may be applied in the manufacture of overhead cables for carrying power over long distances.
