Aluminum-Yttrium (Al-Y) Master Alloy | High-Purity Rare Earth Aluminum Modifier

Our Aluminum-Yttrium master alloy is independently vacuum-smelted in our Ganzhou factory. As a high-performance rare earth aluminum intermediate alloy, it is widely used to uniformly introduce yttrium into aluminum melt, refine grain structure, improve thermal stability and comprehensive mechanical properties of aluminum alloys. It features high element recovery rate and extremely uniform microstructure.

We supply standard industrial grades and support fully customized yttrium content. All rare earth raw materials adopt 3N/4N high-purity yttrium metal to ensure ultra-low impurity control and stable batch consistency.

Important Notice: This product contains controlled heavy rare earth element (Yttrium). Export from China requires official dual-use item export license.
