### **Product Introduction: Magnesium Dysprosium Master Alloy (Mg-Dy Alloy)** **Product Names:** * Magnesium Dysprosium Master Alloy * Mg-Dy Alloy * MgDy10 Alloy, MgDy20 Alloy, MgDy30 Alloy #### **Overview** Magnesium Dysprosium Master Alloy is a premium alloying agent engineered for the precise and efficient introduction of Dysprosium (Dy) into magnesium (Mg) melts. Dysprosium is a heavy rare-earth element renowned for its exceptional ability to improve the high-temperature strength and creep resistance of magnesium alloys. It is particularly effective in strengthening the grain boundaries, making it a critical additive for alloys intended for use in demanding thermal and mechanical environments. Our Mg-Dy Master Alloy ensures excellent dissolution, high Dy yield, and precise compositional control for developing advanced magnesium alloys. #### **Key Features & Advantages** * **Superior High-Temperature Performance:** Dramatically enhances strength, stability, and creep resistance at elevated temperatures (typically above 300°C), outperforming many other alloying elements. * **Effective Grain Boundary Strengthening:** Dysprosium segregates to grain boundaries, forming thermally stable precipitates that inhibit grain boundary sliding at high temperatures. * **Synergistic Alloying:** Often used in combination with other Heavy Rare Earths (HRE) like Gadolinium (Gd) and Yttrium (Y) to create complex, high-strength alloy systems (e.g., Mg-Gd-Dy-Y series) with optimized properties. * **Good Corrosion Resistance:** Contributes to the formation of a more protective surface oxide, improving the overall corrosion resistance of the base magnesium. * **Precise Composition Control:** Guarantees uniform distribution and high recovery rate of the valuable dysprosium, ensuring consistent and reliable performance in final cast or wrought products. --- ### **Chemical Composition** Our Mg-Dy Master Alloy is available in several standard grades to meet diverse application needs. Typical chemical compositions are as follows: | Element | MgDy10 | MgDy20 | MgDy30 | Impurities (Max.) | | :--- | :--- | :--- | :--- | :--- | | **Dy (Dysprosium)** | 9.0 - 11.0% | 18.0 - 22.0% | 28.0 - 32.0% | - | | **Mg (Magnesium)** | Balance | Balance | Balance | - | | **Fe (Iron)** | ≤ 0.01% | ≤ 0.01% | ≤ 0.01% | 0.02% | | **Si (Silicon)** | ≤ 0.01% | ≤ 0.01% | ≤ 0.01% | 0.02% | | **Cu (Copper)** | ≤ 0.005% | ≤ 0.005% | ≤ 0.005% | 0.01% | | **Ni (Nickel)** | ≤ 0.002% | ≤ 0.002% | ≤ 0.002% | 0.005% | | **Other Single RE** | ≤ 0.05% | ≤ 0.05% | ≤ 0.05% | 0.10% | *Note: Custom compositions, including specific Dy content and tailored multi-rare earth combinations (e.g., Mg-Dy-Gd), are available upon request.* --- ### **Physical Properties** | Property | Typical Value / Description | | :--- | :--- | | **Form** | Ingot, Notched Ingot, Lump | | **Ingot Size** | Customizable (e.g., 2-10 kg per ingot) | | **Color** | Metallic Gray | | **Melting Point** | Varies with Dy content; approximately **~600°C - 650°C** | | **Density** | Varies with Dy content; approximately **~1.8 - 2.2 g/cm³** | --- ### **Applications** Mg-Dy Master Alloy is primarily used in the most demanding applications where magnesium components must retain their mechanical integrity under significant stress at high temperatures. Its key applications are in aerospace and advanced defense systems. * **Aerospace & Aviation:** * Engine components: gearbox housings, compressor casings, and engine mounts. * Transmission parts for helicopters and aircraft. * Structural components for missiles and spacecraft operating under high thermal loads. * **Defense & Military:** * Lightweight armor systems. * Housings for guidance systems and other avionics requiring high dimensional stability. * **High-Performance Automotive:** * Components for advanced powertrains and engines in racing and luxury sports cars. * **Specialized Engineering:** * Parts for high-speed manufacturing and processing equipment that operates at elevated temperatures. The alloys produced, such as those in the **Mg-Gd-Dy-** based systems, are typically used in both cast and wrought forms and are known for their peak-aged strength at temperatures around 250-300°C. --- ### **International Standards** The production and use of Mg-Dy Master Alloy conform to the general principles and specifications for high-quality magnesium-rare earth alloys. While specific Dy-containing alloys are often proprietary, they are governed under broader standards. * **ASTM International:** * **ASTM B93/B93M:** Standard Specification for Magnesium Alloys in Ingot Form for Sand Castings, Permanent Mold Castings, and Die Castings. This is the primary standard governing the quality of master alloy ingots for further processing. * **Aerospace Material Specifications (AMS):** * While no standard AMS for a specific Mg-Dy alloy exists, the resulting cast or wrought products would be qualified to standards like **AMS 4427** (for Mg-Y-RE alloys), demonstrating the performance level required. * **European Standards (EN):** * **EN 1753:** Magnesium and magnesium alloys - Magnesium alloy ingots and castings. Provides a framework for the chemical and mechanical properties of advanced Mg-RE alloys. * **Chinese Standards (GB):** * **GB/T 19078:** Standard for Magnesium Alloy Ingots. This standard encompasses specifications for various rare-earth containing magnesium alloys, including those with heavy rare earths like Dysprosium. --- ### **Packaging & Handling** * **Packaging:** Packed in sealed, moisture-proof plastic bags or vacuum-packed to prevent oxidation. The bags are then placed in robust, lined steel drums or wooden crates to ensure integrity during shipping and storage. * **Storage:** Store in a cool, dry, and well-ventilated area. Keep away from corrosive chemicals, acids, and open flames. * **Handling:** Handle with standard industrial safety procedures for reactive metals. Use appropriate personal protective equipment (PPE) including gloves and safety glasses. The alloy may react with water or moisture to produce flammable hydrogen gas. --- **Contact Us:** For further technical information, pricing on MgDy10, MgDy20, MgDy30 grades, or to discuss custom alloy requirements, please contact our technical sales team.
