Magnesium-Silicon (Mg-Si) Master Alloy | High-Purity Magnesium Alloy Modifier

Vacuum-melted Mg-Si master alloy without rare earth elements. High-purity silicon-based magnesium modifier for magnesium alloy performance optimization and casting improvement. Custom composition available

Magnesium-Silicon (Mg-Si) Master Alloy | High-Purity Magnesium Alloy Modifier


Our Magnesium-Silicon master alloy is independently vacuum-melted in our Ganzhou factory. This product contains no rare-earth elements, serving as a common and efficient modifier for magnesium alloys. It is mainly used to improve the high-temperature resistance, wear resistance and casting performance of magnesium alloys, with stable component ratio and high melting utilization rate.

We supply standard industrial grades and support fully customized silicon content. With strict impurity control and stable batch quality, it is widely applied in ordinary magnesium alloy casting and industrial modification scenarios.
