Hexcel® HexWeb® CR-PAA™ 1/4-5056-0.0025 Phosphoric Acid Anodized Aluminum Honeycomb
Categories:	Metal; Metal Foam, Mesh, or Honeycomb; Nonferrous Metal; Aluminum Alloy; 5000 Series Aluminum Alloy
Material Notes:	Grade is designated as "Cell Size-Alloy-Foil Gauge." The life cycle of aluminum honeycomb sandwich structures in a given application can be directly related to the quality of the bond between the face sheets that carry bending loads and the honeycomb that carries the shear loads. The adhesive is the interface between the facing and the core in the same way that the oxide on the aluminum and the primer that has been applied to it is the interface between the honeycomb substrate material and the bonding adhesive. This interface is critical to the performance of honeycomb bonded assemblies. HexWeb® CR-PAA™ is designed for aircraft structures that are exposed to demanding environmental conditions. HexWeb® CR-PAA™ outperforms standard MIL-C-7438 core in salt spray and HexWeb® crack propagation tests.
