Metal honeycomb encompasses metallic core structures — most commonly aluminium alloy, titanium, or stainless steel — manufactured by expansion or corrugation of foil into hexagonal, over-expanded, or flex-core cell geometries, used as lightweight sandwich panel cores in primary and secondary aerostructures, with cell density, foil gauge, and node-bond integrity governed by relevant ASTM and MIL specifications.
