How to choose aluminum honeycomb as core material for wall cladding panels?
Sep 04, 2017

When aluminium honeycomb core used as core for wall cladding panels, aluminium alloy A303H18 is required.

Aluminum honeycomb core cell size can be 3/8 inch, cell node 6mm with aluminium foil thickness 0.06mm.

The aluminum wall cladding panel is for exterior use, so the aluminium foil to make honeycomb core should be anti corrosion. Besides, work as composite panel's core, the honeycomb walls should be perforated with micro hole to let the air come out so the composite panel will not bubble after years use.


Here's some technical dat sheet of aluminium honeycomb core:
