TS-065429 — Iron is the main and most detrimental impurity in most industrial casting aluminum alloys. Iron content in aluminum alloys is limited, up to 0.1 weight% in some alloys.
Iron is a major impurity element in primary and secondary (scrap) aluminum alloys. It is difficult to remove during melting and casting. Controlling the formation of Al-Fe-based intermetallics via alloying is key to leveraging the mechanical properties of aluminum alloy products. The current struc…
