The effects of rare earth (RE) alloys on the refining and modifying of cast aluminum alloys were investigated. Compared to other substances in common use, rare earth alloys maintain the refining and modifying effects of the aluminum alloys for a longer time. RE alloys can also reduce environmental pollution in the melting process. These effects of RE alloys make them become a superior choice for the applications in aluminum foundry.
