### **Product Introduction: Magnesium Samarium Master Alloy (Mg-Sm Alloy)** **Product Names:** - Magnesium Samarium Master Alloy - Mg-Sm Alloy - MgSm Alloy - MgSm20, MgSm30 #### **Overview** Magnesium Samarium Master Alloy is a specialized rare-earth master alloy engineered for the precise introduction of Samarium (Sm) into magnesium melts. Samarium, as a medium-heavy rare-earth element, offers an exceptional balance of high-temperature strength enhancement and cost-effectiveness. This master alloy is particularly effective in improving creep resistance, thermal stability, and mechanical properties at elevated temperatures, making it an ideal choice for applications requiring sustained performance in warm environments. Mg-Sm master alloys demonstrate superior aging response and microstructural stability compared to many conventional alloying systems. #### **Key Features & Advantages** - **Excellent High-Temperature Strength:** Significantly improves tensile and creep properties at temperatures up to 300°C - **Superior Aging Kinetics:** Exhibits strong precipitation hardening response with stable Sm-containing precipitates - **Enhanced Thermal Stability:** Maintains mechanical properties during prolonged exposure to elevated temperatures - **Cost-Effective RE Solution:** Provides rare-earth benefits at a more favorable cost than heavy rare-earth alternatives - **Good Corrosion Resistance:** Improves general and stress corrosion resistance in various environments - **Microstructural Stability:** Inhibits grain growth and maintains fine microstructure at high temperatures - **Controlled Solubility:** Offers predictable dissolution characteristics and high recovery rates --- ### **Chemical Composition** Our Mg-Sm Master Alloy is produced under controlled atmosphere conditions to ensure precise chemical composition and minimize oxidation. | Element | MgSm20 | MgSm30 | Impurities (Max.) | |---------|---------|---------|-------------------| | **Sm (Samarium)** | 18.0 -
