STUDY ON THE Al-Mg ALLOYS BASED ON HIGHT-PURITY ALUMINUM (Part 1)

On the "Reflectal" Alloy

Abstract

Recently, the Al-Mg alloy based on high-purity aluminum are used for reflectors, utensils, fittings, dentistry and jewellery in abroad.
Electrolytically polished and anodized high-purity aluminum (99.99%up) has excellent reflection properties, but its strength is too low to use for them. It is said that an addition of 0.3-1.0% Mg improves its strength without deteriorating the reflection properties and corrosion resistance. These alloys are called as Reflectal, Lurium and etc.
In this paper the properties of Raffinal, Reflectal 0.5, Reflectal 1.0 and other alloys are compared with those of 99.7%Al to ascertain the effect of Mg addition.
