For the purpose of finding Al alloys, which possess strong resistance against corrosion and high hardness for dental use, Mg, Si, Cu, and Ag also were selected as the additional elements; because their properties are known to strengthen the material and not to weaken the corrosion resistance of Al. Various tests have been made on these Al alloys, and the best results were obtained from the alloys containing these elements;-- 4% Si and 3% Mg; 4% Mg and 3% Cu. These alloys were not ideal, but nevertheless suitable for dental use, because of their good corrosion resistance and considerable hardness.
