PAA-SDFH® PAA-SDFH® (Phosphoric Acid Anodized-Showa Double Flexible Honeycomb) 4.8-5052-47

PAA-SDFH® PAA-SDFH® (Phosphoric Acid Anodized-Showa Double Flexible Honeycomb) 4.8-5052-47 is an aerospace grade 5052 aluminum honeycomb materials produced from phosphoric acid anodized aluminum sheets. Phosphoric acid anodize gives an excellent corrosion resistance to aluminum alloy, and the surface treatment system with a corrosion prohibited primer provide the greatest bondability and fatigue strength under critical conditions such as hot & wet condition. PAA-SDFH is available in two selections of core density and foil thickness.

Applications

PAA-SDFH has been developed to enhance the properties of standard aluminum honeycomb against the corrosion. The enhanced corrosion protection of PAA-SDFH can provide a potential to reduce a life cycle cost or/and to reduce manufacturing cost occurred for additional processes to improve corrosion protection and durability of the standard aluminum honeycomb. For this reason, PAA-SDFH will be an alternative for the standard aluminum honeycomb being used for the bonded assemblies of aircrafts.
