Introduction of Quantitative Analysis of Aluminum Alloys and Matching Function

User Benefits

- Enables analysis of Mg in aluminum alloys, which was difficult with conventional EDXRF. - The series of aluminum alloys can be distinguished by using the matching function. - Supports diverse size of samples, from small specimens to A4 size.

Introduction

In aluminum alloys, elements such as copper, manganese, and silicon, are added to aluminum to improve its machinability, abrasion resistance and corrosion resistance. Depending on the composition, aluminum alloys are classified as 1000 to 8000 series. The energy dispersive X-ray fluorescence spectrometer (EDXRF) is widely used for quality control of aluminum alloys and acceptance inspections of recycled materials. However, analysis of light elements (particularly Mg) had been difficult until now due to the inadequate sensitivity and resolution. The Shimadzu EDX- 8100 offers greatly enhanced performance in the light element region, enabling quantitative analysis of Mg at levels of 0.1 % or less. This article introduces the following: 1.Quantitative analysis and accuracy evaluation by the calibration curve method (preparation of calibration curves using standard samples and repeatability testing) 2. FP (fundamental parameter) qualitative/quantitative analysis and matching function
