Copper‑Yttrium (Cu‑Y) Master Alloy | Rare‑Earth Copper Intermediate Alloy

Our Copper‑Yttrium master alloy is independently vacuum‑smelted in our Ganzhou factory. As a high‑performance rare‑earth copper intermediate alloy, Cu‑Y is widely used to introduce yttrium uniformly into molten copper, refine grain‑structure, improve high‑temperature oxidation‑resistance, thermal‑stability and mechanical properties of copper and copper‑alloy products. Rare‑earth raw‑material adopts 3N/4N high‑purity yttrium metal. Standard grades and fully‑customized yttrium‑content specifications are offered.

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

Chemical Composition

Custom yttrium proportion and special specifications are available on request.
