The multiyear contract, valued at more than $1 billion, is the largest ever between the two companies.
Alcoa plate products, such as wing ribs and skins, will also be on every Boeing platform. The Boeing next-generation 737, is one of the world's most successful commercial airliners and features Alcoa aluminium.
“This historic agreement not only continues the 35-year Alcoa-Boeing partnership, it will take our collaboration on next-generation metallic technologies even further,” said Klaus Kleinfeld, Alcoa Chairman and Chief Executive Officer.
“We are proud that Alcoa's lightweight structural solutions will continue to fly on Boeing’s most advanced aircraft today, and that our metallic science leadership will contribute to the Boeing aircraft of tomorrow.”
Notably, the agreement makes Alcoa sole supplier to Boeing for wing skins on all of its metallic structure airplanes. Alcoa plate products, used in applications such as wing ribs, wing skins or other structural parts of the aircraft, will also be on every Boeing platform, including the 787 Dreamliner.
Finally, the agreement establishes a foundation for continued collaboration on new, high-strength and corrosion-resistant alloys, including aluminium-lithium that could be used for complex structural applications.
