Abstract

The rapid annealling of Al based alloy electrical conductors which are in the form of wires, strips, ribbons, flats is described. The machine wire, previously wire drawn by a reduction of S - s/s. >=1,000% (where S and s are resp. the cross-sectional areas of the machine wire and of the wire of intermediate dia), is subjected to static recovery leading to a state close to the start of recrystallisation. The wire is then drawn to the desired final dia. and fast annealed at >=350 degrees C for a time between a fraction of a second and a minute. The relationship between the properties of the wire, ie. fracture strength; elongation to rupture; and resistivity is equivalent to that obtd. by static annealing over long periods.
