Copper-Cerium (Cu-Ce) Master Alloy | High Temperature Resistant Rare Earth Copper Modifier

Our Copper-Cerium (Cu-Ce) master alloy is independently vacuum-smelted in our Ganzhou factory. As a high-performance rare earth copper intermediate alloy, it is widely used as a professional modification additive for copper and copper alloy melt. Uniformly dispersed cerium elements effectively refine coarse grain structure, eliminate internal casting defects, and significantly enhance high-temperature oxidation resistance, thermal stability and wear resistance of copper products.

We supply stable industrial-grade Cu-Ce master alloy and fully support customized cerium content ratios. Adopting high-purity rare earth raw materials and strict impurity control, each batch maintains consistent metallurgical performance, suitable for high-end electrical copper materials, high-temperature copper components and industrial precision casting production.
