ABSTRACT:
A process for the manufacture of wires and profiles, wherein thermoplastics are first mixed, in the melt, with from 5 to 40 per cent by weight (based on the mixture) of aluminum needles of length from 0.3 to 6 mm, of average diameter from 0.02 to 0.1 mm and of length to average diameter ratio of from 3 to 100, the mixture is extruded to give a wire or profile in which the aluminum needles are substantially oriented axially, and this wire or profile is finally hardened by cold-working.
