Copper‑Lithium (Cu‑Li) Master Alloy | Functional Copper‑Based Intermediate Alloy

Vacuum‑melted Cu‑Li master alloy without rare‑earth elements. Lithium‑copper modifier for de‑oxidation, grain‑refinement and copper‑alloy performance‑adjustment, custom lithium‑content available.

Our Copper‑Lithium master alloy is independently vacuum‑melted in‑house. This rare‑earth‑free intermediate alloy serves as powerful de‑oxidizer and grain‑refining additive for molten copper. Lithium elements distribute uniformly, removing oxygen‑related inclusions and improving microstructure and mechanical properties of finished copper‑alloy parts. We supply standard industrial grades and fully‑customizable lithium ratios. Strict anti‑oxidation production control ensures low impurity and stable batch‑consistency。
