SeAH Aerospace & Defense Recognized with Boeing’s Prestigious Award
On June 10, 2026, SeAH Aerospace & Defense (SeAH AD) received significant recognition by winning Boeing's Supplier Production Partner Award during the Boeing Supplier Summit. This prestigious accolade is awarded to suppliers who provide exceptional contributions within Boeing's commercial aviation supply chain. SeAH AD's performance and operational excellence have marked its successful partnership with Boeing in a competitive market.
Outstanding Contributions to Aerospace Materials
SeAH AD has been a key supplier of aluminum extrusion materials specifically designed for Boeing aircraft. The company extended its partnership with Boeing by signing a multi-year contract in December 2025, further solidifying its role as a crucial player in aviation materials.
As the only company in Korea capable of producing aerospace-grade aluminum extrusion materials, SeAH AD specializes in high-strength 2000 and 7000 series aluminum alloys. These alloys are essential for constructing fuselages and wings, offering advantages such as superior fatigue resistance and lightweight properties that directly contribute to the aircraft's performance.
Innovations in Manufacturing
The 2000 series of aluminum alloys stands out for its excellent resistance to wear and heat, which is vital in extending the lifespan of aircraft skin structures. Meanwhile, the 7000 series provides robustness akin to steel while being significantly lighter, enhancing overall efficiency and performance in aerospace applications.
SeAH AD has also achieved numerous milestones in the field of aerospace manufacturing. Notably, in collaboration with SeAH CSS, the company developed Korea’s first prototype AI7050 spar structural component for commercial aircraft wings.
Since 2023, SeAH AD has been supplying two types of wing spar forgings for 190 Gulfstream G280 aircraft produced by Israel Aerospace Industries (IAI). Furthermore, in 2024, the company localized the production of AL7136 aluminum extrusion material, enabling them to mass-produce components for Brazilian aerospace manufacturer Embraer.
Future Investments and Expansion
SeAH AD is actively investing in its growth and capabilities by constructing a state-of-the-art second manufacturing facility in Changnyeong, South Korea. Expected to be completed in the first half of 2027, this facility will utilize cutting-edge technology aimed at expanding production capacities for aircraft fuselage and wing applications.
With the aim of optimizing materials supply chains across Northeast Asia, including China, Japan, Southeast Asia, and India, this facility will play a critical role in strengthening SeAH AD's global presence.
Commitment to Quality and Excellence
The representatives of SeAH AD have emphasized their commitment to enhancing competitiveness as a premier global supplier of aerospace materials. They highlighted their focus on stabilizing operations at the Changnyeong facility while aiming to be a trusted partner for key global aircraft manufacturers.
This level of dedication and quality management equips SeAH AD to maintain its leading position in the aerospace materials sector and respond effectively to the demands of a dynamic market, thus ensuring long-term success and reliability for its partners and customers.
