SeAH Aerospace Materials, a subsidiary of SeAH Besteel Holdings, announced a long-term agreement yesterday (December 15) to supply high-strength aluminum alloy to Boeing, a leading global aircraft manufacturer.

This contract extends their existing partnership, meaning that SeAH will begin providing high-strength aluminum alloy, used for aircraft fuselage and wings, starting next year. The deal reflects SeAH's proven material quality and reliable supply chain, leading to a strategic collaboration.

This deal also guarantees production volume for SeAH's new 2,300-ton aluminum materials plant in Changnyeong, planned for operation in 2027. This commitment will support the facility’s smooth launch and increase its cost efficiency, making SeAH meet growing aerospace demand.
