### **Product Introduction: Magnesium Scandium Master Alloy (Mg-Sc Alloy)** **Product Names:** - Magnesium Scandium Master Alloy - Mg-Sc Alloy - Magnesium Scandium Alloy - MgSc2, MgSc5, MgSc10, MgSc20, MgSc30 #### **Overview** Magnesium Scandium Master Alloy represents the pinnacle of high-performance magnesium alloy technology, combining magnesium with scandium - one of the most effective but expensive alloying elements for lightweight metals. Scandium produces exceptional improvements in strength, weldability, and thermal stability, making Mg-Sc alloys the material of choice for premium aerospace, defense, and high-performance applications. The addition of scandium refines grain structure, enhances precipitation hardening response, and significantly improves mechanical properties without compromising corrosion resistance. #### **Key Features & Advantages** - **Exceptional Strength-to-Weight Ratio:** Achieves the highest specific strength among commercially available magnesium alloys - **Superior Weldability:** Enables fusion welding without significant loss of mechanical properties in heat-affected zones - **Excellent Thermal Stability:** Maintains mechanical properties at elevated temperatures up to 350°C - **Grain Refinement:** Provides dramatic grain size reduction, enhancing both strength and ductility - **Age Hardening Response:** Exhibits strong precipitation strengthening with scandium-containing precipitates - **Corrosion Resistance:** Maintains excellent corrosion resistance comparable to conventional magnesium alloys - **Recrystallization Inhibition:** Suppresses grain growth during thermal processing and welding --- ### **Chemical Composition** Our Mg-Sc Master Alloy is produced under strict atmospheric control to prevent oxidation and ensure precise composition. | Element | MgSc2 | MgSc5 | MgSc10 | MgSc20 | MgSc30 | Impurities (Max.) | |---------|-------|-------|--------|--------|--------|-------------------| | **Sc (Scandium)** | 1.8-2.2% | 4.5-5.5% | 9.0-11.0% | 18.0-22.0% | 28.0-32.0% | -
