Abstract
On degrease annealing of thin strip and foil made of aluminum and aluminum alloys in an annealing furnace ozone is introduced into the furnace atmosphere. As a result of this the annealing time can be shortened or the annealing temperature lowered. Likewise the tendency for the foil to stick together when in coiled form is markedly reduced.
