For people who know aluminum...here's the lettering inside box and what A.I. says... QQ-A-561: This is a federal specification for Aluminum Alloy Plate and Sheet, 1100. low to moderate strength applications. 1100: This designates the aluminum alloy type. 1100 aluminum is considered commercially pure, with a minimum purity of 99% aluminum. It is a soft and ductile alloy, excellent corrosion resistance, workability, and weldability. It is not heat-treatable. H14: This is a temper designation that indicates the material has been strain hardened (cold-worked) to a half-hard state without being thermally treated. The H signifies that the material's properties were enhanced through strain hardening.  ALCLAD: This indicates that the aluminum sheet is a composite material consisting of a high-strength aluminum alloy core with a thin outer layer of pure aluminum. The pure aluminum layer provides excellent corrosion resistance, while the alloy core maintains the required strength. This type of material is widely used in the aircraft industry for parts like fuselages and structural components. ALCOA: This is an acronym for the Aluminum Company of America, a major global producer of aluminum products. The marking identifies the manufacturer of the material. .050: This number refers to the thickness of the aluminum sheet in inches. This indicates a sheet that is 50 thousandths of an inch thick.  ^004...weight 6 lb boxed  has scratches, slight dent on box side no handle grommets
