Aluminium is a kind of active metal, in the smelting process is easy to produce aluminium oxides, some non-metallic inclusions are also easy to enter the melt, due to the fine oxide particle density and aluminium similar, generally suspended in liquid aluminium, with liquid aluminiuim static method is difficult to remove, affecting the quality of casting.

1. Degassing: Aluminium alloy refining flux can remove hydrogen and other volatile gases in aluminium liquid through chemical reaction. 2. Slag removal: Refining flux can absorb and dissolve oxidized inclusions in aluminium alloy. 3. Refining grain: Refining flux can refine the grain of aluminium alloy, improve its organization, and improve the purity of melt. 4. Environmental protection and safety: Aluminium alloy refining flux uses non-toxic ingredients to reduce the potential harm to the environment and human health. 5. Economic benefits: It can significantly improve the quality and performance of aluminium alloy, reduce subsequent processing costs, improve production efficiency and economic benefits.
