Abstract
Aluminium foundry alloys are often contaminated with non-metallic inclusion particles in forms of oxides, carbides, and spinel. These inclusions can lead to significantly reduce of mechanical properties of aluminium foundry alloy. Fluxing treatment is one of the conventional methods for removing inclusions and oxides from the melt to enhance the quality of aluminium foundry alloy. In this study, we used several recipes of metal treatments and flux dosages and investigate the quality of A356.2. Filtration graphic by Prefil Footprinter and hydrogen content data by AlScan Hydrogen Analyzer were obtained to fully analyze the mechanism and get the best fluxing parameters.
