Reflecting Surfaces of Aluminum

Aluminum is inherently a good reflector of radiation in the ultraviolet, visible, and infra-red portions of the spectrum. Means of developing and maintaining this high reflectivity in commercial reflectors are described. The new Alzak process of electrolytic brightening and oxide coating makes available aluminum reflectors, both specular and diffuse, having reflection factors up to about 85 per cent. The Alzak reflectors have a hard, abrasion resisting coating of clear transparent aluminum oxide on the surface which makes them weather-resistant and easily cleaned.
