Magnesium Yttrium Neodymium Master Alloy,,E FOUR

### **Product Introduction: Magnesium Yttrium Neodymium Master Alloy (Mg-Y-Nd Alloy)** **Product Names:** - Magnesium Yttrium Neodymium Master Alloy - Mg-Y-Nd Master Alloy - Mg-Y-Nd Alloy #### **Overview** Magnesium Yttrium Neodymium Master Alloy represents an advanced ternary alloying system that combines the superior high-temperature properties of Yttrium (Y) with the excellent room-temperature strengthening characteristics of Neodymium (Nd). This sophisticated master alloy is specifically engineered to create magnesium alloys that deliver balanced performance across a wide temperature range, from ambient to elevated temperatures (250-300°C). The synergistic interaction between Y and Nd results in optimized mechanical properties, making it an ideal choice for applications requiring comprehensive performance reliability. #### **Key Features & Advantages** - **Balanced Performance Profile:** Yttrium ensures outstanding high-temperature strength and creep resistance, while Neodymium provides superior room-temperature strength and aging response - **Enhanced Thermal Stability:** Maintains mechanical integrity and dimensional stability at elevated temperatures up to 300°C - **Optimized Precipitation Strengthening:** Facilitates the formation of complex, thermally stable precipitates that resist coarsening at high temperatures - **Improved Corrosion Resistance:** The combined effect of Y and Nd enhances the formation of protective surface films, significantly improving corrosion resistance compared to conventional magnesium alloys - **Excellent Castability:** Ensures good fluidity and reduced hot cracking tendency during casting processes - **Cost-Effective Performance:** Provides an optimal balance between performance and cost compared to heavy rare-earth containing alloys --- ### **Chemical Composition** Our Mg-Y-Nd Master Alloy is available in standardized grades designed to meet specific application requirements and final alloy specifications. | Element | MGYN54 (Standard Grade) | MGYN83 (High-Performance Grade) | Impurities (Max.) | |---------|--------------------------|----------------------------------|-------------------| | **Y (Yttrium)** | 4.0 - 5.0% | 7.5 - 8.5% | - | | **Nd (Neodymium)** | 3.0 - 4.0% | 2.5 - 3.5% | - | | **Mg (Magnesium)** | Balance | Balance | - | | **Y+Nd Total** | 7.0 - 9.0% | 10.0 - 12.0% | - | | **Fe (Iron)** | ≤ 0.01% | ≤ 0.01% | 0.02% | | **Si (Silicon)** | ≤ 0.01% | ≤ 0.01% | 0.02% | | **Cu (Copper)** | ≤ 0.005% | ≤ 0.005% | 0.01% | | **Ni (Nickel)** | ≤ 0.002% | ≤ 0.002% | 0.005% | | **Other Single RE** | ≤ 0.05% | ≤ 0.05% | 0.10% | *Custom compositions with specific Y:Nd ratios and total rare earth content are available upon request to meet specialized application needs.* --- ### **Physical Properties** | Property | Typical Value / Description | |----------|-----------------------------| | **Form** | Ingot, Notched Ingot, Lump | | **Ingot Size** | Customizable (2-15 kg per ingot) | | **Color** | Metallic Gray with slight yellowish tint | | **Melting Point** | ~610°C - 650°C (composition dependent) | | **Density** | ~1.8 - 2.0 g/cm³ | | **Hardness** | 50-70 HB | --- ### **Applications** Mg-Y-Nd Master Alloy is primarily utilized in applications requiring a balanced combination of room-temperature and elevated-temperature properties across various demanding industries. - **Aerospace Industry:** - Aircraft transmission housings and gearboxes - Engine accessory components and mounts - Helicopter rotating components - Satellite structural components - **Automotive Sector:** - High-performance engine blocks and cylinder heads - Transmission cases for luxury and sports vehicles - Turbocharger housings and components - Engine mounting brackets - **Defense Applications:** - Lightweight armor components - Military vehicle transmission systems - Portable equipment housings - **Industrial Applications:** - High-speed manufacturing equipment components - Robotics and automation system parts - Precision instrument housings --- ### **International Standards** The Mg-Y-Nd Master Alloy and resulting magnesium alloys conform to established international standards for high-performance magnesium-rare earth alloys. - **ASTM International:** - **ASTM B93/B93M:** Standard Specification for Magnesium Alloys in Ingot Form for Sand Castings, Permanent Mold Castings, and Die Castings - **ASTM B80:** Standard Specification for Magnesium-Alloy Sand Castings - **ASTM B107/B107M:** Standard Specification for Magnesium-Alloy Extruded Bars, Rods, Profiles, Tubes, and Wire - **SAE International:** - **SAE AMS 4425:** Magnesium Alloy Castings, Sand 3.0Nd - 2.5Zn - 0.6Zr - 0.5Y (ZE63A-T6) - **SAE AMS 4416:** Magnesium Alloy Castings, Sand 3.5Nd - 1.3Gd - 0.15Zn - 0.5Zr (EV31A-T6) - **European Standards (EN):** - **EN 1753:** Magnesium and magnesium alloys - Magnesium alloy ingots and castings - **EN 12438:** Magnesium and magnesium alloys - Magnesium alloys for cast anodes - **Chinese Standards (GB):** - **GB/T 19078:** Magnesium alloy ingots - **GB/T 5153:** Wrought magnesium alloys --- ### **Packaging & Handling** - **Packaging:** Vacuum-sealed in moisture-proof aluminum laminate bags, followed by packaging in sealed, corrosion-inhibited steel drums or wooden crates - **Storage:** Store in a cool, dry, well-ventilated area with relative humidity below 60%.
