Aluminum honeycomb core is made up of layers and aluminum foil adhesive, overlying, and then stretched into a regular hexagonal honeycomb core. Aluminum honeycomb core hole wall with sharp, clear, without burrs, suitable for high quality across the core material of adhesive and other purpose. Honeycomb board core layer is hexagonal aluminum honeycomb structure, containment of dense honeycomb like many wall beams, can bear the pressure from the other side of the panel, the plate force uniform, ensure the panel in a large area can still keep high flatness. In addition, the hollow honeycomb can also greatly abate the plate body thermal expansion. In the form of the supply full blocks of honeycomb. Cut slices of honeycomb, expanded honeycomb, perforated honeycomb, corrosion treated honeycomb.
