SeAH Aerospace & Defense Becomes Korea's First Aluminum Alloy Supplier for Airbus

Key Highlights:

• Recognized for its superior process control and quality standards, SeAH A&D signed a long-term agreement with Airbus ahead of final product certification.
• The company will begin the quality certification process in the second half of this year to supply high-strength aluminum alloys for Airbus fuselages and wings.
• Building on its recent success with Boeing, SeAH A&D's entry into the Airbus supply chain accelerates its emergence as a key global partner for advanced aviation materials.

SEOUL, South Korea, July 26, 2026 /PRNewswire/ -- SeAH Aerospace & Defense (SeAH A&D) announced a historic long-term agreement (LTA) to supply high-strength aluminum alloy materials to Airbus. Formalized at the Farnborough International Airshow 2026, this milestone contract makes SeAH A&D the first Korean materials company to secure such a direct supply agreement with Airbus.

Under the agreement, SeAH A&D will begin the quality certification process in the second half of this year for its high-strength aluminum alloys, which are critical materials used in Airbus aircraft fuselages and wing structures. The company plans to launch full-scale production and supply starting in 2028.

Breaking from industry conventions, this LTA was signed before the completion of product certification. The commitment is a strategic response to accelerating supply chain bottlenecks caused by soaring aircraft demand alongside a limited supply of aviation materials meeting strict specifications. It closely aligns Airbus' strategy to secure a stable procurement network early on with SeAH A&D's advanced process control technology and world-class quality standards.

Leveraging its proven technological prowess, SeAH A&D continues to expand its footprint in the global aviation aluminum alloy market, a sector traditionally dominated by large materials companies in Europe and the U.S. The company currently supplies materials to Israel Aerospace Industries (IAI) and Embraer. It further demonstrated its advanced manufacturing capabilities by signing an LTA with Boeing in December of last year. To meet the growing global demand for aviation materials, a new manufacturing facility in Changnyeong, Korea, is scheduled to begin operations in 2027. This expansion is expected to solidify SeAH A&D's position as a key direct supplier of raw materials to major aerospace component manufacturers across the Asia-Pacific region, including China, Japan, Southeast Asia and India.

At the Farnborough International Airshow 2026, SeAH A&D plans to actively engage in business meetings and strategic networking to expand its global reach. The company will showcase its achievements in supplying various aluminum alloy materials for aviation and defense applications, spanning commercial aircraft, military aircraft and urban air mobility (UAM). In particular, the company plans to heavily promote its optimized process control technology that achieves both airframe lightweighting and structural stability. The showcase will spotlight high-strength aluminum extrusions for major Airbus wing and fuselage structures, which demand precise material control and stringent quality standards.

"Securing a place in the Airbus supply chain is a significant milestone that validates the superior quality and reliable delivery of our high-strength aluminum alloys on the global stage," said a representative of SeAH A&D. "As we advance toward final certification and build a robust supply network, we are cementing our position as a leading global aviation materials company representing Asia."
