SEOUL, Korea, June 11, 2026 — SeAH Aerospace & Defense (SeAH A&D) has been honored with Boeing’s Supplier Production Partner Award at the Boeing Supplier Summit, recognizing the company’s outstanding performance and operational excellence within Boeing’s commercial aircraft supply chain.

The award acknowledges suppliers that have demonstrated exceptional contributions across Boeing’s global commercial aviation supply network. SeAH A&D, which has been supplying aluminum extrusion materials for Boeing aircraft, signed a multi-year contract extension with Boeing in December 2025.

SeAH A&D is the only company in Korea with the capability to manufacture aerospace-grade aluminum extrusion materials. The company supplies high-strength 2000 and 7000 series aluminum alloys for aircraft fuselage and wing structures to the global aerospace market.

The 2000 series alloys offer excellent fatigue resistance and heat resistance, making them critical materials that directly impact the lifespan of aircraft skin structures. The 7000 series alloys provide steel-like strength while weighing only about one-third as much, positioning them as high-value aerospace materials that deliver both structural integrity and lightweight performance.

SeAH A&D has also achieved several notable milestones in aerospace manufacturing. In collaboration with SeAH CSS, the company successfully developed Korea’s first prototype AI7050 spar structural component for commercial aircraft wings. Since 2023, it has been supplying two types of wing spar forgings for a total of 190 Gulfstream G280 aircraft produced by Israel Aerospace Industries (IAI). In 2024, SeAH A&D became the first company in Korea to localize the production of AL7136 aluminum extrusion material for aerospace components and is currently mass-producing aluminum materials for aircraft parts to be supplied to Embraer, one of Brazil’s leading aerospace manufacturers.

SeAH A&D is also undertaking a major investment to build a state-of-the-art second manufacturing facility in Changnyeong, Korea. Scheduled for completion in the first half of 2027, the new plant will feature world-class equipment and systems dedicated to producing aluminum extrusion materials for aircraft fuselage and wing applications. Moving forward, SeAH A&D plans to significantly expand its aerospace materials manufacturing capacity through a dual-facility strategy, integrating the production capabilities of its existing and new plants with greater operational flexibility.

Leveraging Korea’s advanced manufacturing infrastructure and strategic geographic location, SeAH A&D is expanding its global footprint by directly supplying raw materials to aerospace manufacturers and suppliers across China, Japan, Southeast Asia, and India, helping optimize regional supply chains. Through these efforts, the company is committed to providing customers with efficient and reliable raw material sourcing solutions.

“Building on our expertise in high-strength aluminum materials and rigorous quality management capabilities, we continue to strengthen our competitiveness as a key global supplier of aerospace materials,” said a representative of SeAH A&D. “Following our record-breaking performance last year, we will focus on the rapid stabilization of our new Changnyeong facility and further establish ourselves as a leading Korean aerospace materials company, while strengthening our position as a trusted supply chain partner to global aircraft manufacturers.”
