半岛bd体育手机客户端 介绍

The Honeycomb is made from Aluminium alloy foil which is chemically treated, node bonded and expanded to form a low density material used principally as a shear-carrying-core in lightweight sandwich constructions.

We stock both honeycomb core and skinned lightweight sandwich panels made using some of these cores.

The typical properties of the honeycomb cores stocked which are all made from 5052 Aluminium alloy are shown in the data table.

Other densities, cell sizes and core and foil thicknesses available on request.
