Magnesium-Cerium Master Alloy Description
Magnesium-Cerium (Mg-Ce) master alloy is an intermetallic compound composed of magnesium (Mg) and cerium (Ce) in various proportions. It is produced by melting and alloying pure magnesium with cerium metal. This process enables grain refinement, improved high-temperature performance, corrosion resistance and alloy modification. Mg-Ce master alloys are used in several sectors, including the automotive industry, aerospace and chemical processing.

Specification of the Magnesium-Cerium Master Alloy
Rare earths (RE) have been successfully alloyed with magnesium. The addition of RE refines the grain structure and reduces anisotropy, thereby enhancing the ductility of Mg alloys. Additionally, RE elements form a dispersion of thermally stable precipitates with a melting point exceeding 620 °C, which is significantly higher than the approximately 340 °C melting point of precipitates in the Mg-Zn system, thereby reducing the risk of hot tearing.
Magnesium-Cerium Master Alloy Packaging
The Magnesium-Cerium master alloy from SAM is carefully processed to minimise damage during storage and transport, thereby preserving the product quality in its original condition.
