Magnesium-Erbium (Mg-Er) Master Alloy | High-Purity Rare Earth Magnesium Alloy

Our Magnesium-Erbium master alloy is independently vacuum-melted in our Ganzhou factory. It is a high-performance rare earth magnesium alloy, widely used to improve the corrosion resistance, grain refinement and comprehensive mechanical properties of magnesium-based materials. Erbium elements are uniformly distributed with high recovery rate during melting process.

We supply standard industrial grades and support fully customized erbium content according to customer technical requirements. All erbium raw materials adopt 3N/4N high-purity rare earth metals to ensure ultra-low impurity control and stable batch quality.
