Magnesium AZ80A-F, Forged，UNS M11800,E FOUR

Product Datasheet: Magnesium Alloy AZ80A-F (Forged), UNS M11800** **Overview** Magnesium Alloy AZ80A is a high-strength, heat-treatable wrought magnesium alloy. The "-F" temper designation specifically indicates that the product is in the "as-fabricated" condition, meaning it has been shaped by a forging process without a subsequent heat treatment. Forging aligns the grain structure, resulting in superior mechanical properties—particularly high strength, good ductility, and excellent fatigue resistance—compared to its cast counterparts. UNS M11800 is the Unified Numbering System identifier for this alloy. This alloy is renowned for being one of the strongest commercially available magnesium alloys in wrought forms and is primarily chosen for lightweight structural applications where strength-to-weight ratio is critical. **Key Advantages** * **Exceptional Strength-to-Weight Ratio:** Offers high tensile and compressive strength while being approximately 35% lighter than aluminum and 75% lighter than steel. * **Good Ductility and Toughness:** The forging process provides a fine, uniform grain structure that enhances toughness and resistance to impact. * **Excellent Damping Capacity:** Effectively absorbs vibration and noise, making it ideal for dynamic components. * **Good Machinability:** Can be machined at high speeds with excellent surface finish and low energy consumption. **Chemical Composition (Typical Weight %)** The composition conforms to major international standards for AZ80A alloy. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Aluminum (Al)** | 7.8 - 9.2 | **Zinc (Zn)** | 0.2 - 0.8 | | **Manganese (Mn)** | 0.12 - 0.50 | **Silicon (Si)** | ≤ 0.10 | | **Copper (Cu)** | ≤ 0.05 | **Iron (Fe)** | ≤ 0.005 | | **Nickel (Ni)** | ≤ 0.005 | **Other Impurities** | ≤ 0.30 | | **Magnesium (Mg)** | Balance | | | *Note: The low levels of iron, copper, and nickel are critical for providing improved corrosion resistance compared to standard AZ alloys.* **Physical & Mechanical Properties (Typical for Forged Condition)** The following values are typical and can vary based on the specific forging design (die design, reduction ratio, etc.). | Property | Metric Unit | Imperial Unit | | :--- | :--- | :--- | | **Density** | 1.80 g/cm³ | 0.065 lb/in³ | | **Melting Range** | ~ 430 - 590 °C | ~ 806 - 1094 °F | | **Ultimate Tensile Strength (UTS)** | 310 - 345 MPa | 45 - 50 ksi | | **Tensile Yield Strength (0.2% Offset)** | 215 - 240 MPa | 31 - 35 ksi | | **Elongation (in 50 mm / 2 in)** | 6 - 11 % | 6 - 11 % | | **Compressive Yield Strength** | 215 - 240 MPa | 31 - 35 ksi | | **Shear Strength** | ~ 180 MPa | ~ 26 ksi | | **Hardness (Brinell)** | 70 - 80 HB | 70 - 80 HB | | **Modulus of Elasticity** | 45 GPa | 6.5 x 10⁶ psi | | **Fatigue Strength (Rotating Beam, 5x10⁸ cycles)** | ~ 130 MPa | ~ 19 ksi | **International Standards** Magnesium AZ80A-F forging stock and forgings are covered by the following standards: * **ASTM International:** * **ASTM B107/B107M:** Standard Specification for Magnesium-Alloy Extruded Bars, Rods, Profiles, Tubes, and Wire. (Often referenced for forging stock/billets). * **ASTM B91:** Standard Specification for Magnesium-Alloy Forgings. This is the primary standard for forged AZ80A components. * **SAE International:** * **SAE AMS 4357:** Covers Magnesium Alloy Forgings (AZ80A-F). * **Unified Numbering System (UNS):** * **UNS M11800** * **European Standards (Similar Designations):** * **EN 1753:** Mg-Al8-Zn (Designation for a similar alloy family). **Product Applications** Forged AZ80A components are critical in industries where saving weight directly translates to improved performance, efficiency, and payload capacity. * **Aerospace & Defense:** * Aircraft landing wheels, gearbox housings, and transmission components. * Helicopter rotor hubs and gearbox parts. * Missile and rocket body sections, fins, and guidance system housings. * **Automotive & Racing:** * High-performance steering wheels, wheel rims. * Gearbox cases, clutch housings, and engine brackets. * Suspension components and pedal assemblies. * **Other Industrial Applications:** * Portable tools and equipment housings (e.g., chain saws, grinders) to reduce operator fatigue. * Components for textile and printing machinery requiring high-speed, low-inertia parts. * Sports equipment, such as bicycle frames and components, and climbing gear. **Handling & Considerations** * **Corrosion Protection:** While AZ80A offers improved corrosion resistance, unprotected magnesium is susceptible to corrosion in wet or saline environments. Components typically require a protective coating system (e.g., chemical conversion coatings, anodizing, paint, or plating) for long-term service. * **Joining:** Can be joined using adhesive bonding and mechanical fastening. Specialized techniques are required for welding. * **High-Temperature Use:** Mechanical properties decline significantly at temperatures above approximately 120°C (250°F). --- **Disclaimer:** The information provided herein is for reference purposes only.
