### **Product Introduction: Magnesium Silicon Master Alloy (Mg-Si Alloy)** **Product Names:** - Magnesium Silicon Master Alloy - Mg-Si Alloy - MgSi Alloy #### **Overview** Magnesium Silicon Master Alloy is an efficient and economical alloying agent designed for introducing silicon into magnesium and aluminum melts. The formation of magnesium silicide (Mg₂Si) phases provides effective strengthening through precipitation hardening mechanisms. This master alloy is particularly valued for its ability to improve elevated temperature properties, wear resistance, and dimensional stability while being an environmentally friendly and cost-effective alternative to rare-earth containing alloys. #### **Key Features & Advantages** - **Effective Strengthening:** Forms stable Mg₂Si intermetallic compounds that provide precipitation strengthening - **Improved High-Temperature Properties:** Enhances creep resistance and maintains strength at elevated temperatures - **Excellent Wear Resistance:** Hard Mg₂Si particles improve abrasion resistance in final alloys - **Cost-Effective Solution:** Provides performance enhancement at a fraction of the cost of rare-earth additions - **Environmentally Friendly:** Contains no hazardous or restricted elements - **Good Fluidity:** Improves castability and reduces hot tearing tendency - **Recyclability:** Fully compatible with recycling processes --- ### **Chemical Composition** Our Mg-Si Master Alloy is available in various silicon content grades to meet different application requirements. | Element | Standard Grade | High Silicon Grade | Impurities (Max.) | |---------|----------------|---------------------|-------------------| | **Si (Silicon)** | 28.0 -
