Aluminium Honeycomb Core Aluminium honeycombs and panels made with it offer the advantage of lightness, compression and shear resistance, fire and corrosion resistance and the possibility to be recycled. Aluminium honeycomb is used in a number of applications, for example in railways, in shipbuilding, in aviation, in cleanroom sector, for printing pallets and building industry etc. Aluminium honeycomb is used as core material for sandwich panels: floors, roofs, doors and partitions, facades, working surfaces for automatic machines and for all products which require an optimal stiffnessto-weight-ratio. Aluminium honeycomb as panels’ core is the winner because of: • lightness • stiffness • fire resistance • compression, shear and corrosion resistance • flatness Aluminium honeycomb without skins can be used as deflector for laminar flow-ventilation, and as crash-absorber for absorbing kinetic energy. Regarding the aluminium honeycomb the client can choose a thickness from 3 until 300 mm, a cell size from 6.4 until 25.4 mm and a density from 20kg/m3 until 85kg/m3 (density depends on foil thickness and cell size). NOTE: 1.6mm, 3.2mm & 4.8mm cell size and aluminium alloy 5052 is also available. Additional densities and configurations available upon request.
