Alcoa (NYSE:AA) has signed an approximately $1 billion contract with Airbus for high-tech, multi-material aerospace fastening systems.

The deal is Alcoa’s largest fastener contract ever with the aircraft manufacturer. Alcoa’s fasteners fly on every Airbus platform.

“Our growing aerospace capabilities, technology strength and global, first-rate customer service continue to strengthen Alcoa’s decades-long partnership with Airbus,” said Alcoa Chairman and Chief Executive Officer Klaus Kleinfeld. “Alcoa is proud to partner with Airbus to provide breakthrough technologies for some of the most advanced aircraft in the world.”

Alcoa’s fasteners will be used to assemble some of Airbus’s latest high-growth airplanes, including the A350 XWB, Airbus’ newest commercial airplane, and the A320neo. In addition, Airbus will use Alcoa’s fastening systems for longer-running platforms including the A330.

As part of this agreement, Alcoa will supply advanced fastening systems, such as those that enhance the assembly of aircraft panels and engine pylons on newer airplanes with sophisticated design features. Alcoa’s fasteners are made using a variety of materials including stainless steel, titanium and nickel-based superalloys, which improve fatigue life, enable lightning strike protection, and improve wear and reusability on conventional and composite aircraft. Alcoa will produce these fastening systems at 14 of its global manufacturing facilities.
