Removal of iron from recycled aluminium alloys

Iron is considered as an impurity in aluminium alloys due to its detrimental impact on strength and ductility. Much work has been carried out to reduce the iron levels in recycled aluminium alloys. In this investigation, the influence of Mn additions for reducing the Fe content in an Al–Si alloy has been studied. The experimental results and thermodynamic calculations revealed that a reduction of up to 62%Fe content can be achieved. The major …
