Zusammenfassung:	Provided is a Fe-Mn-Al-C lightweight steel, comprising: Fe, having a weight percentage greater than or equal to 50.4 wt%; Mn, having a weight percentage of 25-35 wt%; Al, having a weight percentage of 6-12 wt%; C, having a weight percentage of 0.8-2.0 wt%; and O, having a weight percentage of 0.005-0.6 wt%. The present application also provides a terminal using the Fe-Mn-Al-C lightweight steel, a preparation method for the Fe-Mn-Al-C lightweight steel, a steel structure, and an electronic device. The lightweight steel of the present application has low density, high strength, and high ductility.
