SOME FINDINGS ON THE ELOXAL CAST ALLOYS AND ELOXAL CASTINGS,

Abstract

Increasing the titanium content within the frame established by DIN 1725/2 for the alloys G-AlMg3 and 241 G-AlMg3(Cu) within 0-0.20% range refines the grain and makes the grain size less susceptible to the overheating of the smelting product. The higher titanium content impairs the glaze of the Eloxal somewhat, as do the higher concentrations of magnesium and silicon. The detrimental action of the silicon is not due to its penetration into the anodically built oxide layer. In addition, this layer becomes interrupted at those spots in which the Mg2Si separations appear. The foundation is also pitted by these. A discussion of the imperfections of the Eloxal layers due to the silicon refining process, to the different crystal orientation and to heat curing follows. (Author)
