The honeycomb aluminum aeronautical grade is produced by thin aluminum strip of 5000. The protection is applied on the tape against corrosion of atmospheric agents. There are several sections of cells and density. The honeycomb is produced by bonding aluminum sheets that damage all'esagno expanded form. The honeycomb can be provided in blocks, unexpanded strips and expanded sheets. The thickness is chosen by the customer. The material can be perforated for communicating all the cells between them (for vacuum application and space).
Some cells can be expanded in OX shape (rectangular) to allow the curvature in one direction.
- High resistance to compression and shear / Weight reduction
- Corrosion resistant and fire / recyclable material
It is used in various aero fields (airplanes, helicopters, radar), automotive (racing cars), RF shelding to ensuring a long life and resistance to moisture and temperature.
The standard size is mm1220x2440. General tolerances - 50 / + 100 mm - On request special sizes. The thickness is chosen by the customer: minimum 1.5 mm up to 500 mm depending on the type of cell. Tolerance standard +/- 0.12 mm or +/- 0.05mm with extracost.
