### **Product Introduction: Magnesium Ytterbium Master Alloy (Mg-Yb Alloy)** **Product Names:** - Magnesium Ytterbium Master Alloy - Mg-Yb Alloy - MgYb Alloy - MgYb20, MgYb30, MgYb50 #### **Overview** Magnesium Ytterbium Master Alloy is a specialized heavy rare-earth master alloy engineered for the precise introduction of Ytterbium (Yb) into magnesium melts. Ytterbium, as a heavy rare-earth element, offers unique advantages in enhancing high-temperature strength, creep resistance, and modifying the microstructure of magnesium alloys. This master alloy is particularly valued for its ability to improve mechanical properties at elevated temperatures and its relatively lower neutron absorption cross-section, making it suitable for specialized applications in aerospace and nuclear industries. #### **Key Features & Advantages** - **Exceptional High-Temperature Performance:** Significantly improves creep resistance and mechanical properties retention up to 300°C - **Effective Solid Solution Strengthening:** Ytterbium provides substantial solid solution strengthening in magnesium matrix - **Grain Refinement:** Contributes to finer grain structure and improved mechanical properties - **Moderate Neutron Absorption:** Suitable for nuclear applications where controlled neutron absorption is required - **Improved Corrosion Resistance:** Enhances general and stress corrosion resistance in various environments - **Thermal Stability:** Maintains mechanical properties during prolonged exposure to elevated temperatures - **Controlled Solubility:** Offers predictable dissolution characteristics and high recovery rates --- ### **Chemical Composition** Our Mg-Yb Master Alloy is produced under controlled atmosphere conditions to ensure precise chemical composition and minimize oxidation. | Element | MgYb20 | MgYb30 | MgYb50 | Impurities (Max.) | |---------|---------|---------|---------|-------------------| | **Yb (Ytterbium)** | 18.0 -
