Do you need to perform analysis of unalloyed magnesium according to ISO 8287?
Securing metallic materials for the ASD sector with ISO 8287
In the Aerospace, Space, and Defense (ASD) sectors, the use of magnesium is essential for applications requiring maximum mass reduction. However, the chemical purity of this metal is a safety imperative. The presence of impurities outside of tolerances can alter mechanical performance and accelerate the corrosion of your essential parts.
ISO 8287 specifies sampling methods and chemical composition requirements for unalloyed magnesium. It defines acceptable limits for common impurities (Iron, Silicon, Copper, Manganese...) to guarantee the quality of the base metal before alloying or direct use.
At FILAB, we support manufacturers in the ASD supply chain with the characterization and control of their materials according to ISO 8287. Our goal is clear: to ensure the reliability of your technical and industrial decisions.
ISO 8287: A key challenge for light alloys
Magnesium purity analysis according to ISO 8287
The ISO 8287 standard defines magnesium purity grades (from 99.8% to 99.98% and above) and governs the analyses required to validate these quality levels. It generally relies on atomic emission spectrometry techniques to quantify traces of undesirable elements.
It is specifically used to:
- Precisely measure trace elements: Iron (Fe), Silicon (Si), Copper (Cu), Manganese (Mn), Aluminum (Al).
- Verify compliance of magnesium ingots against industrial grades.
- Guarantee the absence of contaminants that could promote galvanic corrosion.
In the Aerospace and Defense industries, adhering to ISO 8287 specifications has a direct impact on:
- Chemical stability of the material in humid environments.
- Castability properties when creating complex alloys.
- Long-term reliability of strategic components such as engine casings or internal structural elements.

FAQ
ISO 8287 deals exclusively with unalloyed magnesium (used as a raw material). For alloys (such as AZ91), other analytical standards apply, although the measurement techniques remain similar.
Iron and Copper are particularly monitored because, even at very low levels, they drastically reduce magnesium's corrosion resistance.
Depending on the sample geometry, we use either Spark-OES (direct on solid) for speed, or ICP-OES (after acid digestion) for increased precision on very low impurity levels.
Although ISO 8287 focuses on metallic impurities, Filab can complement this analysis with Hydrogen determination by Inert Gas Fusion, a critical element to avoid porosity in casting.
