Aluminum 6013-T651 is a medium-strength aerospace alloy containing magnesium and silicon as the major alloying elements. It offers improved formability, lower density, and corrosion resistance compared to other aerospace alloys like 2024. Aluminum 6013-T651 sheet/plate is commonly used for aircraft fuselage panels, engine cowlings, leading/trailing edges, and other structural components requiring a combination of strength, formability, and corrosion resistance.
