6.4mm (1/4") Cell Aluminium Honeycomb

High performance aluminium honeycomb core material exactly as supplied to the world's top composites engineering, aerospace and motorsport manufacturers.

Used correctly, aluminium honeycomb can be used to reduce the weight and increase the stiffness of composite panels in a wide range of applications:

This medium 6.4mm / 1/4" cell size honeycomb is an excellent 'all rounder' honeycomb suitable for a wide range of applications including motorsport, marine, renewable energy and transport. The 6.4mm / 1/4" cell size is a good balance between strength, weight and cost making this our most popular aluminium honeycomb.

How to Buy

Thickness

The honeycomb listed on this page is available in 10mm, 15mm and 20mm thicknesses. Please choose the thickness you require from the options at the top of the page.

Sheet Sizes (once expanded)

We stock and ship all our aluminium honeycomb in unexpanded block form (see below). This makes them much smaller and more cost effective to ship but also, importantly, ensures that they can be delivered undamaged, ready to be expanded into an undamaged sheet of honeycomb.

Sheets are available in blocks which will expand to a full sheet size of approximately 2500mm x 1250mm, or to a smaller sheet size of 1250mm x 652mm. Please choose the sheet size you require from the drop-down list at the top of the page.

Please note, when expanding aluminium honeycomb, several rows of cells will always be distorted by the expansion process and will generally not be usable which will reduce the usable area of the expanded honeycomb. The expanded sheet dimensions above make some allowance of this but depending on the expansion process, the usable dimensions may be less than those stated above.

Alternative Cell Sizes

We also stock in 1/8" cell size aluminium honeycomb and 3/4" cell size aluminium honeycomb.

Supplied Unexpanded

Due to its fragile nature and large dimensions, aluminium honeycomb is supplied unexpanded in block form and must be expanded before use.

In industry, a specialist expanding machine is used to expand the honeycomb on site. Where an expansion machine is not available, the honeycomb can be expanded by hand using an improved rig; depending on the cell size and thickness, this can vary from easy, to difficult, to do. If you plan to expand the aluminium honeycomb by hand, please read our Guide to Expanding Aluminium Honeycomb by Hand. Altiveners cannot be held responsible for damage caused to the honeycomb by the expansion method employed.
