PAA-CORE® 5052 aluminum core honeycomb is phosphoric acid anodized and coated with a proprietary primer. PAA-CORE® has unsurpassed corrosion resistance, (with minimal weight loss after 31 days in an acidified salt spray chamber). PAA-CORE® outperforms non-metallic core materials due to significantly higher strength-to-weight ratio and hot/wet strength.

Using a phosphoric acid anodized metal treatment process developed by Boeing, The Gill Corporation-Maryland introduced the industry to PAA-Core CORE aluminum honeycomb back in 1988. (PAA stands for phosphoric acid anodized.) This is highly corrosion-resistant aluminum honeycomb core with excellent bonding capability and durability. It is an accepted replacement for non-metallic core with an outstanding record. One of its distinctions is a high strength to weight ratio. Over a decade of operational experience has shown that bond durability between core and skins is critical to long part life, and for this, PAA-CORE® has no equal.

Independent analysis confirms the environmental performance durability of PAA-CORE®, assuring a lower total life cost than with other core materials. PAA-CORE® also has unsurpassed corrosion resistance, experiencing only minimal weight loss and virtually no loss of physical properties after extended exposure in an acidified salt spray chamber, which simulates the harshest environmental conditions.
