### **Product Introduction: Magnesium Cerium Master Alloy (Mg-Ce Alloy)** **Product Names:** - Magnesium Cerium Master Alloy - Mg-Ce Alloy - MgCe20, MgCe25, MgCe30 #### **Overview** Magnesium Cerium Master Alloy represents one of the most cost-effective and widely used rare-earth master alloys for magnesium enhancement. Cerium, as a light rare-earth element, provides exceptional improvements in high-temperature performance, castability, and corrosion resistance. This master alloy is particularly valued for its ability to form thermally stable intermetallic compounds that enhance creep resistance while maintaining excellent oxidation resistance. Mg-Ce master alloy serves as a fundamental building block for numerous commercial magnesium-rare earth alloy systems. #### **Key Features & Advantages** - **Superior High-Temperature Performance:** Significantly improves creep resistance and mechanical properties retention up to 250°C - **Excellent Castability:** Enhances fluidity, reduces microporosity, and minimizes hot cracking tendency - **Oxidation Resistance:** Forms protective surface oxides that reduce melt oxidation during processing - **Cost-Effective RE Solution:** Provides rare-earth benefits at the most economical price point among RE elements - **Grain Refinement:** Contributes to finer grain structure in as-cast conditions - **Improved Corrosion Resistance:** Enhances general and galvanic corrosion performance in various environments --- ### **Chemical Composition** Our Mg-Ce Master Alloy is manufactured with strict control over composition and impurity levels to ensure consistent performance. | Element | MgCe20 | MgCe25 | MgCe30 | Impurities (Max.) | |---------|---------|---------|---------|-------------------| | **Ce (Cerium)** | 18.0 -
