A. When both columns A50mm and A have values, A50mm is suitable for the thickness not greater than 12.5mm, and A is suitable for the thickness greater than 12.5mm.
B. t in the bending radius indicates the thickness of the materials. For the materials with both 90° and 180° bending, if the demander does not specify 90° or 180° bending, the bending radius can be selected by the supplier.
C. For 2014, 2024 and 2219 alloy O plates with a thickness > 12.5mm ~ 25.00mm, the tensile sample is machined from the core material and shall not have an aluminum coating.
