Magnesium Cerium Master Alloy Specification
Rare earth (RE) elements have also been successfully alloyed with Mg. The addition of rare-earth (RE) elements can refine grains and weaken anisotropy to improve the ductility of the Mg alloys. In addition, RE elements give rise to a dispersion of thermally stable precipitates with a high melting point (above 620 °C), an improvement over precipitates of the Mg-Zn system which melt at approximately 340°C and thus have poor thermal stability and exhibit a tendency for hot tearing.

FAQs
Q1: What is Magnesium Cerium Master Alloy?
Magnesium Cerium Master Alloy is a metal alloy that consists primarily of magnesium (Mg) and cerium (Ce). It is used as an additive in the production of magnesium alloys to enhance their properties, such as improving the alloy's strength, corrosion resistance, and heat resistance. It is often used in aerospace, automotive, and electronics industries.
Q2: What are the key properties of Magnesium Cerium Master Alloy?
- Improved Corrosion Resistance: Cerium, as an element in the alloy, helps increase the resistance of magnesium to corrosion, particularly in harsh environments, such as those exposed to moisture or chemicals.
- High Strength: Magnesium alloys that contain cerium tend to have better strength and mechanical properties, making them suitable for structural applications in high-performance industries.
- Heat Resistance: The inclusion of cerium can improve the thermal stability of magnesium alloys, enabling them to withstand higher temperatures without degrading.
Q3: Why is Cerium added to Magnesium Alloys?
- Enhanced Corrosion Resistance: Magnesium alloys are prone to corrosion, especially in humid or saline environments. The addition of cerium helps form a protective oxide layer on the surface of the alloy, reducing the risk of corrosion.
- Improved Strength: Cerium can increase the alloy's mechanical properties, such as tensile strength and yield strength, which is crucial for applications where strength is a priority.
- Better Castability: Cerium has the ability to refine the grain structure of magnesium alloys, making them easier to cast and ensuring better quality and fewer defects in the final product.
