Corex Honeycomb has an automated expansion table and can supply expanded honeycomb sheets. The company also offers expansion equipment such as the “hand expander ” tool to customers and can provide technical advice on different expansion methods. Please contact the sales team for more information. For more information see our expansion video.

Honeycomb is manufactured in an unexpanded format and can be supplied in unexpanded slices to save transport charges and storage space. When the honeycomb is unexpanded, the cells are still closed and not yet visible. When the honeycomb is stretched/expanded, the honeycomb expands to its full size and the cells open up and become visible.

Non-volatile adhesive should be used for bonding skins to the honeycomb to prevent possible build-up of volatile substances during the curing process. This may be alleviated by using perforated honeycomb. The adhesive that will be used also depends on other factors such as the application area, skins and the equipment available for bonding. Please contact the sales team for more information. 

Yes, Corex Honeycomb offers a chrome free corrosion treatment. 

For most applications Corex Honeycomb supplies corrosion treated aluminium honeycomb. This means the aluminium foil has a surface coating applied to it before being made into a block. The treatment is carried out in-house and prevents the aluminium from corroding. Furthermore it improves the bonding properties of the aluminium and is therefore recommended for most panel manufacturing applications. 

Drilled honeycomb is for example used for the manufacturing of vacuum tables. For this application simple perforation is not sufficient and larger holes (usually between 3 and 5 mm diameter) are drilled into the unexpanded slices. This allows air to freely circulate between the different cells, once the honeycomb is expanded and bonded into a panel. Since the drilled holes are large and easily visible to the eye, they are sometimes referred to as macro perforation.

During the manufacturing process the aluminium foil is run over a needle roller so that tiny holes that are almost invisible to the eye are punched into the foil before the block is manufactured. This allows fumes from adhesives to vent from the honeycomb during the panel manufacturing process. Since the holes are so small, they are sometimes referred to as micro perforation. 

The ribbon direction is the same as the L direction. 

Alloy 3003 is offered in 50 and 70 micron. 5052 alloy is offered in 35 and 70 micron.

Corex prides itself in offering non-standard sizes to its customers. Non-standard sizes are subject to a minimum of one complete honeycomb block being purchased. Please contact the sales team for more information. 

Slices up to a thickness of approximately 500 mm can be expanded. However, this depends on the density, cell size and the expanded sheet/slice size (W and L direction). In certain cases (large cell size and/or small pieces), sizes over 500 mm can be expanded. Please contact the sales team for more information. 

Blocks made from 3003 alloy have a width of 995 mm. Blocks made from 5052 alloy have a width of either 820 or 1070 mm, depending on the foil thickness.

Corex Honeycomb's standard tolerance is ± 0.25 mm.  

The minimum slice thickness Corex Honeycomb offers is 3 mm

The minimum sheet size that can be achieved for the L direction is 900 mm.

Depending on the cell size and density,  Corex Honeycomb can achieve sizes up to 18000 mm in the W direction and sizes up to 1750 mm in the L direction.

As a standard Corex Honeycomb offers 2500 x 1250 mm and 3000 x 1500 mm. Custom sizes can be offered.

Please refer to the Manufacturing Process for more information.

The aluminium honeycomb block is the end result of the honeycomb manufacturing process. The blocks are unexpanded and usually between 995 and 1070 mm wide (T direction). The width can be cut down into individual unexpanded slices. The thickness depends on the customer requirement. After this the unexpanded slices can be expanded to form the finished expanded sheet. Corex Honeycomb sells honeycomb in all three formats: as blocks, unexpanded slices and expanded sheets. Honeycomb sheets are also referred to as expanded slices. 

Please refer to the aluminium honeycomb manufacturing process.

Corex Honeycomb usually holds stock of standard blocks with the cell sizes ¾” (19.1 mm), 3/8” (9.5 mm), ¼” (6.4 mm) and 1/8” (3.2 mm). Other cell sizes may also be available from stock. More information on densities and stock material is available upon request. Please contact the sales team for more information. 

Corex Honeycomb prides itself in offering short lead times to its customers. Generally speaking material can be offered within a time frame of 1 to 3 weeks. Corex Honeycomb hold certain blocks in stock and these blocks or slices from the blocks can normally be supplied within a few working days. The lead times also depend on the order level at the time and the quantity required. Please contact the sales team with your enquiries for more specific lead times. 

Corex Honeycomb offers aluminium honeycomb made from the alloys 3003 and 5052 and is looking to increase its range to include 5056 in the near future.

See the Corex Honeycomb applications page for more details.

Aluminium honeycomb is used in a variety of different industries such as the Marine, Rail, Aerospace, Construction and Architectural and Automotive Industry. Honeycomb is also used for more specialised usages such as air flow straightening, clean rooms and ventilation applications. The application areas for aluminium honeycomb are very versatile and the material can be used almost any place where a very good strength to weight ratio is required.
