What aluminum alloys meet NSF certification for public spaces?

When specifying aluminum for public spaces, NSF certification is crucial for safety and compliance. The primary NSF standards relevant to aluminum alloys include NSF/ANSI 51 for food equipment, NSF/ANSI 61 for drinking water system components, and NSF H1 for non-food contact surfaces where lubricants might be used. Common aluminum alloys like 6061 and 6063 are frequently certified under these standards, provided they meet specific composition and surface treatment requirements. For NSF/ANSI 51, alloys used in food contact surfaces must not leach harmful substances. For NSF/ANSI 61, alloys in contact with drinking water must pass strict leaching tests. Always verify certification for the specific alloy, product form, and manufacturer with NSF International to ensure your project meets all necessary public health standards.
