### **Product Introduction: Magnesium Barium Master Alloy (Mg-Ba Alloy)** **Product Names:** - Magnesium Barium Master Alloy - Mg-Ba Alloy - Mg5Ba Alloy, Mg10Ba Alloy #### **Overview** Magnesium Barium Master Alloy is a specialized alloying agent designed for the controlled introduction of Barium (Ba) into magnesium and aluminum melts. Barium serves as an effective grain refiner and oxide modifier, significantly improving the mechanical properties and castability of the final alloys. This master alloy is particularly valued for its ability to enhance high-temperature properties and reduce oxidation during melting and processing operations. #### **Key Features & Advantages** - **Effective Grain Refinement:** Barium acts as a powerful grain refiner, resulting in finer microstructure and improved mechanical properties - **Oxidation Resistance:** Significantly reduces melt oxidation during processing, leading to cleaner casts with fewer inclusions - **Improved Fluidity:** Enhances melt fluidity, facilitating the production of complex thin-walled castings - **Cost-Effective Solution:** Provides an economical alternative to rare-earth containing master alloys for specific applications - **Easy Handling:** Offers better handling characteristics compared to pure barium metal - **Environmental Benefits:** Reduces dross formation and metal loss during melting --- ### **Chemical Composition** Our Mg-Ba Master Alloy is manufactured under strict quality control to ensure consistent composition and performance. | Element | Mg5Ba Alloy | Mg10Ba Alloy | Impurities (Max.) | |---------|--------------|---------------|-------------------| | **Ba (Barium)** | 4.5 -
