### **Product Introduction: Magnesium Lithium Master Alloy (Mg-Li Alloy)** **Product Names:** - Magnesium Lithium Master Alloy - Mg-Li Alloy - Mg14Li Alloy, Mg16Li Alloy #### **Overview** Magnesium Lithium Master Alloy represents a breakthrough in lightweight structural materials, combining magnesium with lithium to create the lightest known structural alloys. The addition of lithium significantly reduces density while simultaneously improving ductility and formability. Mg-Li alloys exhibit a unique combination of properties, including ultra-low density, high specific strength, and excellent damping capacity, making them ideal for applications where weight reduction is critical. #### **Key Features & Advantages** - **Ultra-Low Density:** Achieves densities as low as 1.35 g/cm³, approximately 25% lighter than conventional magnesium alloys and 50% lighter than aluminum alloys - **Enhanced Ductility:** Lithium addition transforms the crystal structure from HCP to BCC, significantly improving room-temperature formability and toughness - **Superior Specific Strength:** Outstanding strength-to-weight ratio compared to other structural metals - **Excellent Damping Capacity:** Superior vibration damping characteristics for improved dynamic performance - **Good Machinability:** Easier to machine and form than conventional magnesium alloys - **Radiation Shielding:** Effective for neutron radiation shielding applications --- ### **Chemical Composition** Our Mg-Li Master Alloy is produced under controlled atmosphere to ensure precise lithium content and minimize oxidation. | Element | Mg14Li Alloy | Mg16Li Alloy | Impurities (Max.) | |---------|---------------|---------------|-------------------| | **Li (Lithium)** | 13.5 -
