| Abstract Scope |
Trace elements introduced via scrap can adversely affect the properties of wrought aluminum alloys. Monitoring their content—in both the scrap and all material streams used in melt preparation—is therefore critical. While mobile analyzers are widely used and can detect most trace elements, a more precise analysis requires a stationary instrument with detection and quantification limits below 1 ppm. Spark-OES instruments, commonly used in the aluminum industry, can meet these demands if properly calibrated. This paper presents a detailed example of such a calibration process, including the development of calibration curves for several dozen trace elements. The approach was developed and implemented in an industrial environment, enabling a significant increase in the share of post-consumer scrap used in high-performance wrought aluminum alloys—without compromising final product quality. |
