### **Product Introduction: Magnesium Erbium Master Alloy (Mg-Er Alloy)** **Product Names:** * Magnesium Erbium Master Alloy * Mg-Er Alloy * MgEr20 Alloy, MgEr30 Alloy #### **Overview** Magnesium Erbium Master Alloy is a high-performance alloying agent designed for the precise and efficient introduction of Erbium (Er) into magnesium (Mg) melts. Erbium, a heavy rare-earth element, is a highly effective modifier for magnesium alloys. It significantly enhances strength, particularly at elevated temperatures, and improves corrosion resistance without the high cost associated with some other rare earths. Our Mg-Er Master Alloy offers superior solubility and controllability, making it an ideal choice for developing next-generation, high-strength, and lightweight magnesium alloys. #### **Key Features & Advantages** * **Effective Strengthening:** Erbium provides solid solution strengthening and promotes the formation of stable intermetallic phases, significantly increasing the strength and creep resistance of magnesium alloys, especially at high temperatures. * **Enhanced Corrosion Resistance:** Improves the overall corrosion resistance of the final magnesium alloy by promoting a more stable and protective surface film. * **Grain Refinement:** Contributes to grain refinement in the microstructure, leading to improved mechanical properties and manufacturability. * **Synergistic Effects:** Often used in combination with other rare-earth elements (e.g., Y, Gd) to create synergistic strengthening effects, allowing for the design of alloys with superior performance. * **Cost-Effectiveness:** Offers a favorable balance of performance enhancement and cost compared to other rare-earth elements, providing excellent value. * **Precise Composition Control:** Ensures accurate and uniform addition of erbium, guaranteeing consistent and reproducible results in the final cast or wrought product. --- ### **Chemical Composition** Our Mg-Er Master Alloy is available in standard grades with different erbium contents to suit various application requirements. Typical compositions are as follows: | Element | MgEr20 Alloy | MgEr30 Alloy | Impurities (Max.) | | :--- | :--- | :--- | :--- | | **Er (Erbium)** | 18.0 - 22.0% | 28.0 - 32.0% | - | | **Mg (Magnesium)** | Balance | Balance | - | | **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% | *Note: Custom compositions with specific erbium content, combinations with other rare earths (e.g., Mg-Er-Gd), and tailored impurity levels can be developed 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 with a slight yellowish hue | | **Melting Point** | Varies with Er content; approximately **~600°C - 650°C** | | **Density** | Varies with Er content; approximately **~1.9 - 2.2 g/cm³** | --- ### **Applications** Mg-Er Master Alloy is used to create advanced magnesium alloys for demanding applications where lightweight, high strength, and thermal stability are critical. Its primary use is in aerospace and high-performance engineering. * **Aerospace & Aviation:** * Engine casings and accessory housings. * Gearbox components and transmission parts. * Structural components in aircraft and missiles requiring low weight and high stability. * **Automotive Racing & High-Performance Vehicles:** * Components for engines, transmissions, and turbochargers operating at high temperatures. * Lightweight structural parts to improve power-to-weight ratio. * **Defense Industry:** * Lightweight armor systems. * Housings for portable electronic warfare and communication equipment. * **Advanced Engineering:** * Parts for high-speed manufacturing equipment. * Components in electronic enclosures requiring good strength and damping characteristics. The alloys produced using Mg-Er master alloy are often found in both cast (sand, permanent mold) and wrought (extruded, forged) forms. --- ### **International Standards** While Mg-Er specific alloys are often considered advanced or experimental, their production and the master alloy itself align with general standards for high-purity magnesium-rare earth alloys. Key reference standards include: * **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 guiding standard for the production of master alloys and subsequent casting alloys. * **SAE International:** * **SAE AMS 4418:** Magnesium Alloy, Casting 3.0Er-0.5Zr (Varies). This specific Aerospace Material Standard covers a cast magnesium-erbium alloy, demonstrating its formal application in the aerospace sector. * **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 alloys. * **Chinese Standards (GB):** * **GB/T 19078:** Standard for Magnesium Alloy Ingots. This standard includes specifications for various rare-earth containing magnesium alloys, providing a basis for Mg-Er type alloys. --- ### **Packaging & Handling** * **Packaging:** Securely packed in sealed, moisture-proof plastic bags or vacuum-packed, and then placed in lined steel drums or wooden cases to prevent oxidation and contamination during transport and storage. * **Storage:** Store in a cool, dry, and well-ventilated warehouse. Keep away from fire, heat sources, acids, and oxidizing agents. * **Handling:** Standard industrial safety practices for metallic materials should be followed. Use personal protective equipment (PPE) including gloves and safety glasses. Although stable, the alloy can react with water or acids to produce flammable hydrogen gas. --- **Contact Us:** For detailed technical data sheets, quotation for MgEr20, MgEr30, or other custom grades, please do not hesitate to contact our technical sales department.
