Are there safety risks associated with using magnesium alloys?

Magnesium’s flammability can present safety challenges in aerospace applications.

However, advancements in materials science have led to the development of self-extinguishing magnesium alloys, such as Elektron® 21. This new-generation alloy meets the stringent flammability criteria set by the FAA (Federal Aviation Administration) and EASA (European Union Aviation Safety Agency), making it suitable for critical aerospace applications, including aircraft engine components, helicopter gearboxes, and various interior parts.

In addition to improved safety, these alloys demonstrate enhanced performances at elevated temperatures, such as up to 200 °C.
