### **Product Introduction: Magnesium Lanthanum Master Alloy (Mg-La Alloy)** **Product Names:** - Magnesium Lanthanum Master Alloy - Mg-La Alloy - MgLa20, MgLa30 #### **Overview** Magnesium Lanthanum Master Alloy is a high-performance rare-earth master alloy specifically designed for the introduction of Lanthanum (La) into magnesium melts. As one of the most cost-effective rare earth elements, Lanthanum significantly enhances the high-temperature properties, creep resistance, and castability of magnesium alloys. This master alloy is particularly effective in improving oxidation resistance and mechanical properties at elevated temperatures, making it an ideal choice for automotive and aerospace applications where cost-performance balance is crucial. #### **Key Features & Advantages** - **Excellent High-Temperature Performance:** Improves creep resistance and mechanical properties retention up to 250°C - **Superior Oxidation Resistance:** Forms protective surface oxides that significantly reduce melt oxidation during processing - **Enhanced Castability:** Improves fluidity and reduces hot tearing tendency in cast components - **Cost-Effective RE Solution:** Provides rare-earth benefits at the most economical price point - **Grain Refinement:** Contributes to finer grain structure and improved mechanical properties - **Improved Corrosion Resistance:** Enhances general corrosion resistance in various environments - **Excellent Recyclability:** Fully compatible with standard magnesium recycling processes --- ### **Chemical Composition** Our Mg-La Master Alloy is manufactured under controlled atmosphere conditions to ensure precise chemical composition and high purity. | Element | MgLa20 | MgLa30 | Impurities (Max.) | |---------|---------|---------|-------------------| | **La (Lanthanum)** | 18.0 -
