Vacuum‑smelted Cu‑La‑Ce master alloy in‑house. Mixed rare‑earth copper intermediate additive for grain refinement, oxidation‑resistance improvement of copper alloys, custom composition available.
Our Copper‑Lanthanum‑Cerium master alloy is vacuum‑melted in‑house. It is a multi‑rare‑earth copper modifier designed for copper‑alloy performance optimization. Even‑distributed lanthanum‑cerium rare‑earth components refine copper grain‑structure, inhibit high‑temperature oxidation and improve casting fluidity of molten copper. High‑quality rare‑earth feedstock and strict impurity‑control ensure stable batch‑quality for industrial copper casting and material‑modification projects.
