AFS aluminum foam sandwich

Aluminum foam sandwich is the three layers original material consists of a formed aluminum core sandwiched between two aluminum cover layers, the cover layers are metallic, fused to the core layer without the need for adhesives.

Features of Aluminum foam sandwich:

1. Max. 60% weight savings	Aluminum foam panel has lower density than paper due to its pores and cavities.
2. Flexural and torsional rigidity	The three layers sandwich system provides significantly higher flexural strength than solid sheets of the same weight.
3. Absorption of kinetic energy	Aluminum foam panels delivers an improved solution for vibration and safety due to its acoustic and thermal insulating properties.
4. Wide-ranging processing possibilities	Conventional processes for sheet metal processing can be used when processing aluminum foam sandwich because due to the metallic bond
5. Fire resistance	Aluminum foam sandwich sheets meet stringent fire safety requirements due to the non-adhesive bond of the 3 layers materials
6. 100% recyclable	The foam composite can be fed back into existing materials cycles at the end of its life cycle without any problems.

 
Deep processing of Aluminum foam sandwich:

Deep drawing, punching or pressing	For 3D structure before foaming
Forming	The original sheets can be formed before foaming and then foamed in a forming tool.
Sawing, milling, laser and water jet cutting	Aluminum foam sandwich is an ideally suited for mechanical processing.Milling, sawing, drilling and modern joining techniques are not a problem.
Welding	Generally only the cover layers are welded while the core remains untouched and serves as a kind of welding fixture. As a result, deformation of the components is considerably reduced.
Screwing, reveting and bonding	The material can be easily bonded like conventional aluminum because of its metallic character, thus making it much more cost-effective.
