### **Product Introduction: Magnesium Copper Master Alloy (Mg-Cu Alloy)** **Product Names:** - Magnesium Copper Master Alloy - Mg-Cu Alloy - MgCu Alloy - MgCu20, MgCu30, MgCu50 #### **Overview** Magnesium Copper Master Alloy is a specialized alloying agent designed for the controlled introduction of copper into magnesium and aluminum melts. While copper is not a conventional alloying element for magnesium due to its detrimental effect on corrosion resistance, Mg-Cu master alloy serves specific purposes in specialized applications where high thermal conductivity, improved casting characteristics, or specific mechanical properties are required. This master alloy is primarily used in research applications and specialized industrial processes where its unique properties outweigh corrosion concerns. #### **Key Features & Advantages** - **Enhanced Fluidity:** Significantly improves melt fluidity and casting characteristics - **High Thermal Conductivity:** Copper addition enhances thermal conductivity of final components - **Precipitation Hardening:** Enables age hardening response in specific alloy systems - **Grain Refinement:** Contributes to finer microstructure in as-cast conditions - **Cost-Effective:** Provides copper addition in a readily dissolvable form - **Research Versatility:** Essential for developing specialized alloy systems and material research --- ### **Chemical Composition** Our Mg-Cu Master Alloy is manufactured with precise composition control for consistent performance. | Element | MgCu20 | MgCu30 | MgCu50 | Impurities (Max.) | |---------|---------|---------|---------|-------------------| | **Cu (Copper)** | 18.0 -
