Aluminum-Cerium (Al-Ce) Master Alloy | High-Efficiency Aluminum Grain Refiner

In-house vacuum-smelted Al-Ce master alloy. High-purity cerium aluminum alloy for grain refinement, oxidation resistance and casting performance improvement. Custom grades available.

Our Aluminum-Cerium master alloy is independently vacuum-melted in our Ganzhou factory. It is a high-efficiency rare earth aluminum modifier, widely used to improve oxidation resistance, casting fluidity and grain structure of aluminum alloys. Cerium elements distribute uniformly with high melting utilization rate and stable modification effect.

We supply standard industrial grades and support fully customized cerium content. High-quality rare earth raw materials ensure ultra-low impurities and stable batch consistency.
