Quantitative analysis of aluminum alloy

AppNote XRF1055: quantitative analysis of aluminum alloy

Background

This application note demonstrates the excellent performance of Supermini200 in aluminum alloy analysis. Aluminum alloy, which has the valuable properties of being both “light” and “strong”, is used in many industries such as automobile and aircraft. Since aluminum alloy has a broad range of grades whose characteristics are strongly dependent on the elemental compositions, it is very important to control the components. X-ray fluorescence (XRF) analysis quickly and easily offers precise elemental analysis results to make control of the components in aluminum alloy possible.

Measurements were performed on the Supermini200 for Mg, Si, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Sn and Pb. For the measurement of Sn, a zirconium filter was used to reduce the background to improve the peak to background ratio. The calibration curves were generated using ALCOA spectrochemical standards KA332, KB413, KB514, KC413, SS332, SS380, SS384, SS413 and SS513. Matrix correction was applied to all calibration curves. The correction coefficients were calculated theoretically by the fundamental parameter (FP) method.
