Abstract : The reflectal materials for bright anodizing, made from 99.99% Al, have given excellent results in the most diverse applications with respect to gloss and reflectance; in recent times, however, attempts are being made for economic reasons, to replace these high-purity alloys by less pure and thus cheaper materials, e.g., on basis of Al 99.9 (remiral) or even 99.8/99.85. The improvement of the bright anodizing methods and the many years of experience gained by the processors of these materials have made such a replacement feasible. It must be remembered, however, that an increase in the impurity level makes the achievement of high, uniform gloss more difficult, particularly under actual production conditions, so that compromises with regard to the brightness characteristics, particularly for large, plane surfaces, must be accepted.
