Features of Aluminum foam sandwich:
- Max. 60% weight savings
|
Aluminum foam panel has lower density than paper due to its pores and cavities. |
- Flexural and torsional rigidity
|
The three layers sandwich system provides significantly higher flexural strength than solid sheets of the same weight. |
- Absorption of kinetic energy
|
Aluminum foam panels delivers an improved solution for vibration and safety due to its acoustic and thermal insulating properties. |
- Wide-ranging processing possibilities
|
Conventional processes for sheet metal processing can be used when processing aluminum foam sandwich because due to the metallic bond |
- Fire resistance
|
Aluminum foam sandwich sheets meet stringent fire safety requirements due to the non-adhesive bond of the 3 layers materials |
- 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. |
