SEOUL, December 15 (AJP) - SeAH Aerospace & Defense Materials, a unit of SeAH Besteel Holdings, said on Monday it has signed a long-term supply agreement with Boeing to provide high-strength aluminum alloy materials for commercial aircraft.
Under the deal, SeAH Aerospace will begin supplying aluminum alloys used in aircraft fuselages and wings to the world’s largest aircraft manufacturer from 2026, the company said. Financial terms were not disclosed.
The agreement follows a direct contract signed with Boeing last year, under which SeAH Aerospace demonstrated its quality competitiveness and ability to deliver consistently to the aerospace industry’s stringent standards.
High-strength aluminum alloys used in aircraft structural components require strict process control and quality stability across the entire production chain, from raw material intake and extrusion to heat treatment, machining and inspection.
SeAH Aerospace said its global-standard quality management system and material traceability capabilities met Boeing’s rigorous certification requirements.
The long-term contract also secures initial production volumes for a new 2,300-ton aluminum plant currently under construction in Changnyeong County, which is scheduled to begin full-scale operations in 2027. The facility is expected to support stable operations and improve cost competitiveness.
SeAH continues to expand its high value-added materials portfolio focused on the aerospace and defense sectors. The company already supplies materials to major global aircraft manufacturers, including Airbus Defense and Space, China’s COMAC, Brazil’s Embraer and Canada’s Bombardier.
