Magnesium M1A-F,UNS M15100;,E FOUR

### **Product Datasheet: Magnesium M1A-F (UNS M15100)** **A Commercially Pure Wrought Magnesium Alloy** --- #### **1. Overview** Magnesium M1A-F (UNS M15100) is a commercially pure wrought magnesium alloy containing approximately 1.5% manganese as the primary alloying element. Designated in the "F" temper (as-fabricated), this alloy is not heat-treated after working processes such as extrusion or rolling. M1A is valued for its excellent corrosion resistance - superior to many other magnesium alloys - combined with good weldability and formability, making it suitable for various industrial applications. --- #### **2. Key Features & Advantages** - **Excellent Corrosion Resistance:** Superior to most magnesium-aluminum-zinc alloys in many environments - **Good Weldability:** Can be readily welded using standard techniques - **Adequate Formability:** Can be formed at elevated temperatures - **Good Damping Capacity:** Effectively absorbs vibration and mechanical energy - **Cost-Effective:** Simple composition makes it economically attractive --- #### **3. Chemical Composition (Weight %)** | Element | Mg (Balance) | Mn | Fe (max) | Si (max) | Other Impurities (max) | |---------------|--------------|------------|----------|----------|------------------------| | **Content (%)** | >97.5 | 1.3-2.0 | 0.05 | 0.10 | 0.30 (total) | *Note: The manganese content enhances corrosion resistance by removing iron and other heavy metal impurities into harmless intermetallic compounds.* --- #### **4. Typical Physical & Mechanical Properties** | Property | Value | Condition / Remarks | |---------------------------|------------------------------|---------------------| | **Density** | 1.76 g/cm³ (0.063 lb/in³) | | | **Melting Point** | ~650°C (1202°F) | | | **Tensile Strength (UTS)**| 160-200 MPa (23-29 ksi) | Varies with form | | **Yield Strength (TYS)** | 90-110 MPa (13-16 ksi) | 0.2% offset | | **Elongation** | 5-15% (in 2 inches) | Depends on form | | **Elastic Modulus** | 45 GPa (6.5×10⁶ psi) | | | **Hardness** | 40-50 HB | | --- #### **5. International Standards** M1A is covered by several international standards for wrought products: - **ASTM B107/B107M:** Specification for Magnesium-Alloy Extruded Bars, Rods, Profiles, Tubes, and Wire - **ASTM B90/B90M:** Specification for Magnesium-Alloy Sheet and Plate - **UNS M15100:** Unified Numbering System designation - **AMS 4375:** Aerospace Material Specification for Sheet and Plate - **AMS 4380:** Aerospace Material Specification for Extruded Bars, Shapes, and Tube --- #### **6. Applications** - **Aerospace Components:** Non-structural aircraft parts, covers, and access doors - **Transportation:** Truck and trailer panels, floor boards - **Industrial Equipment:** - Cathodic protection anodes - Grinding wheel cores - Material handling components - **Consumer Goods:** - Luggage frames - Portable tool housings - **Nuclear Industry:** Fuel element cans for certain reactor types --- #### **7. Processing & Fabrication** - **Forming:** Requires hot working at 230-430°C (450-800°F) - **Welding:** Excellent weldability using GTAW (TIG) methods with compatible filler - **Machining:** Excellent machinability with high cutting speeds possible - **Heat Treatment:** None (F temper - as fabricated) - **Corrosion Protection:** Requires standard magnesium protection (chemical conversion coatings, paint) for harsh environments despite good inherent resistance --- **Disclaimer** This technical data is for informational purposes only. Properties may vary depending on manufacturing process, product form, and section size. Users should evaluate the material's suitability for specific applications and consult relevant material specifications before use. Proper safety precautions for magnesium processing must always be followed.
