Popis: The 3003 aluminum alloy melt was treated with three types of melt purification, and the effect of melt purification on the microstructure and mechanical properties of the alloy was investigated. The results show that the impurity content of 3003 aluminum alloy with untreated (UT) reached 0.6801 %. After the process of conventional purification treatment (CPT) and efficient purification treatment (EPT), the impurity content of the alloy decreased significantly, and the fluidity of aluminum melt was improved. Finely dispersed inclusions particles can promote nucleation, refine the size of the cast crystal. Alloy strength and plasticity have increased using the process of CPT and EPT, in particular, EPT is the most obvious. It shows that the purity of aluminum melt plays a key role in the mechanical properties of the alloy.
