What are the differences between plate, sheet, and foil?
All of these fall into the category of flat rolled wrought products, with the thickness of the product determining the category in which it belongs. Plate is defined as having a thickness of 0.250″ or greater, sheet has a thickness of 0.006″ or greater but less than 0.250″, and foil has a thickness below 0.006″. These three products constitute roughly half of the U.S. Aluminum Industry shipments by volume.
