Background

Often, selection of a bauxite mine site is determined by the alumina, silica and iron content of the ore samples. In producing pure aluminum and aluminum alloys, the measurement of trace and alloy component elements is of vital importance to define purity and alloy quality. The concentration of iron is especially important during the smelting process to control the grade of the aluminum produced. In order to ensure consistent production, the levels of iron must be closely monitored in the QA/QC process, and a simple and fast analysis is required at the production line in order to maintain the optimum product output. To meet this industry need, Rigaku offers the NEX QC benchtop EDXRF analyzer, a rugged and reliable tool for the non-destructive measurement of iron and other elements in aluminum.
