Abstract

The disclosure relates to a can lid for food or drink, the can lid including an end and a tab for opening a score formed on the end. The end and/or the tab includes an aluminum alloy containing: Mn: 0.5 mass % to 1.4 mass %, Mg: 2.0 mass % to 4.5 mass %, Si: 0.6 mass % or less, Fe: 0.8 mass % or less, Cu: 0.25 mass % or less, Cr: 0.10 mass % or less, Zn: 0.25 mass % or less, and Ti: 0.10 mass % or less. With this configuration, even if the end and/or the tab contains a recycled aluminum alloy made up of aluminum UBCs as a raw material, a can lid having such an end and/or tab that has properties required for a can lid, such as pressure resisting strength, can be provided.
