Recent advances and future trend of aluminum alloy melt purification: A review

Aluminum, the most produced non-ferrous metal in the world, is highly regarded for its light weight, high specific strength, and excellent thermal conductivity. With the continuous development of aerospace, precision electronics, photovoltaic semiconductors and other emerging strategic industries, the demand for high-performance aluminum alloys is also booming. The paper discusses recent advances in aluminum alloy melt purification, focusing on the development of conventional purification treatment and novel purification treatment of aluminum alloy melt. The advantages and disadvantages of adsorption purification, non-adsorption purification and integrated purification are also summarized. Additionally, the article points out the shortcomings of the current research on aluminum alloy melt purification and gives an outlook on the future research direction.
