Aluminum-Erbium (Al-Er) Master Alloy | High-Purity Rare Earth Aluminum Modifier

In-house vacuum-melted Al-Er master alloy. High-purity erbium-based aluminum intermediate alloy for grain refinement, corrosion resistance and thermal stability improvement. Custom grades available.

Our Aluminum-Erbium master alloy is independently vacuum-melted in our Ganzhou factory. As a high-performance rare earth aluminum modifier, it is widely used to refine aluminum grain structure, improve corrosion resistance and thermal stability. Erbium elements distribute uniformly with high melting recovery rate and stable modification effect.

We supply standard industrial grades and support fully customized erbium content. High-purity rare earth raw materials ensure ultra-low impurities and stable batch quality for industrial and R&D use.
