PAMG-PA3 5052 Aluminum Honeycomb Description: PAMG-PA3 5052 aerospace grade aluminum honeycomb is a phosphoric acid anodized lightweight core material which offers superior corrosion resistance and node bond strength over traditional organo-metallic coated aluminum honeycomb. PAMG-PA3 5052 honeycomb is made from 5052 aluminum alloy foil and meets all the requirements of AMS C7438 Rev A Class 1. Applications: PAMG-PA3 5052 honeycomb uses include aircraft nacelles, aircraft leading and trailing edges, launcher structures, fan casings, fuel cells, fuselage components, and satellite structures. PAMG-PA3 5052 honeycomb is suitable for applications where materials conforming to AMS C7438 Rev A Class 1 are required. PAMG-PA3 5052 honeycomb is available in four forms: unexpanded blocks, unexpanded slices, untrimmed expanded sheets and cut-tosize expanded sheets. It is also available with or without cell perforations to facilitate cell venting for certain applications. Plascore PAMG-PA3 honeycomb is currently not available for 0.0007” foil. • High thermal conductivity • Flame resistant • Excellent moisture and corrosion resistance Cell Sizes: • Fungi resistant • Low weight / High strength • Improved node bond strength for increased formability Tolerances: Length: Width: Thickness: Density: Cell Size: NOTE: + 6", - 0" + 6", - 0" ± .005" (under 4" thick) ± .062" (over 4" thick) ± 10% ± 10% Special dimensions, sizes, tolerances, CNC machining and die cut to size can be provided upon request. Corrosion Resistance: The anodized PA3 coating offers excellent protection for honeycomb cores exposed to corrosive environments, meeting the requirements of AMS C7438 Rev A, CL1. © 2021 Plascore, Inc.
