[China Aluminum Industry Net] rare earth refines the impurity phase in pure aluminum. Rare earths are mainly distributed between grain boundaries and dendrites. They form high-melting intermetallic compounds with impurities such as Fe and Si, and refine the impurities in the Fe-rich phase. At the same time, it has a stable effect on the grain boundary; due to the refinement of the Fe-rich phase and the uniform dispersion, the mechanical properties are greatly improved, the tensile strength increases by 44.18%, the elongation rate increases by 32.04%, and the preferred addition amount of the rare earth is 0.03%.
