What AK does

Dongyang AK Korea Co., Ltd. (AK / (주)동양에이케이코리아) is a South Korean specialty aluminum manufacturer founded on January 29, 2003 and headquartered in Sejong Special Self-Governing Province. The firm operates three integrated factories (Factory 1 extrusion, Factory 2 extrusion, Factory 3 casting + extrusion + cast plate) plus three regional sales offices (Seoul/Gunpo, Hwaseong, Busan) and employs approximately 240 regular staff. AK produces a fully integrated range of aluminum products spanning 1XXX to 7XXX alloy series: high-purity cast billets (5"–41.7" diameter, up to 26.96-ton batch weights), slabs (520T×1,620W×5,600L at 111.40 tons; 700T×2,400W×5,000L at 25.68 tons), extrusions in round, square, drawn, flat, hexa bar, seam and seamless tube forms, and precision cast plates (AKP precision machined; AKC six-sides sawn) with 99.9% porosity-free specification and stress-relief heat treatment.

The firm targets five primary verticals — aerospace, defense/military, shipbuilding/maritime, automotive, and industrial (including molds, tools and semiconductor equipment components) — with documented mechanical performance of 462 MPa tensile and 393 MPa yield strength for its ultra-lightweight high-strength extrusion material. Its commercial model is B2B enterprise field sales with no public or e-commerce pricing, quote-based negotiation, direct sales through the Seoul sales headquarters (covering domestic, special sales for aerospace/naval/vehicle/defense, overseas, and product planning divisions) and regional offices. Aerospace customers served include Korea Aerospace Industries (KAI) under a 2019 KF-X material localization MOU and a 2020 KAI offset program award, with the Defense Acquisition Program Administration (DAPA) having granted AK an exclusive license for aerospace/defense aluminum production and sales in December 2018. Certifications include AS9100 (aerospace QMS), NADCAP NDT-UT (aerospace special process), IATF 16949 (automotive QMS), ISO 9001, ISO 14001, and KS D 6759.

Core offering

AK (Dongyang AK Korea) is a fully integrated aluminum manufacturer producing high-purity aluminum billets, slabs, extruded profiles (bars and tubes), and precision-machined cast plates. The company operates three factories in Sejong, South Korea covering casting, extrusion, and cast plate production, and supplies aluminum materials to aerospace, defense, automotive, shipbuilding, railway, and industrial sectors. It holds an exclusive license for aerospace and defense aluminum production and sales from South Korea's Defense Acquisition Program Administration.

Product overview

AK (동양AK / Dongyang AK Korea) is an aluminum manufacturing company with a fully integrated production system covering three main product categories: Casting (주조), Extrusion (압출), and Cast Plate (캐스트 플레이트). The casting division produces high-purity aluminum billets (5" to 41.7" diameter) and slabs (520T×1620W and 700T×2400W sizes) in 1XXX to 7XXX alloy series. The extrusion division manufactures various aluminum profiles including round bars, square bars, drawn bars, flat bars, hexa bars, seam tubes, and seamless tubes for aerospace, defense, automotive, shipbuilding, and industrial applications. The cast plate division produces precision-machined aluminum plates (AKP series) and six-sides sawn aluminum plates (AKC series) in various alloys (5052, 5083, 6061, 7021) and tempers. The company operates three factories and three sales offices, serving aerospace, defense, semiconductor equipment, automotive, shipbuilding, and general industrial sectors.
