Changsung

What Changsung does

Chang Sung Corporation is a South Korean advanced materials manufacturer founded in November 1980 and headquartered in Incheon, South Korea. The company operates seven distinct product lines built around metal powder production and soft magnetic materials science: metal powders (for 3D printing, MLCC, and electronic materials), soft magnetic powder cores (MPP, High Flux, Sendust, Mega Flux, HS, HP, and Titanium Grade variants), coils and inductors, functional pastes, EMC materials, clad metals, and powder metallurgy products. Underlying capabilities span atomization, soft magnetic material development, clad metal pressure welding, and functional paste formulation, anchored by proprietary processes such as the patented MPP powder manufacturing method (1998) and the Mega Flux core series, which the company claims achieves the highest magnetic flux density (16,000 Gauss) in its category and a "Global No.1" market position in soft magnetic powder cores. The High Flux GT series reportedly delivers approximately 25% lower core loss at 200kHz than prior generations, targeting EV powertrain, server, and onboard charger applications.

Changsung sells primarily through B2B enterprise field sales with product-specific inquiry channels and quote-based pricing for custom material solutions, supplemented by international distribution partnerships (e.g., MRC in Germany) and an online sample shop for smaller orders. The customer base spans four primary verticals: automotive (EV, hybrid, and traditional OEMs), renewable energy (solar inverters), electronics (IT, communications, mobile), and industrial manufacturing. Manufacturing is vertically integrated across six facilities in five countries — Incheon, Pyeongtaek, and Cheongju in Korea; Weihai, China (since 2005–2007); Queretaro, Mexico (April 2023); and Chennai, India (October 2024) — positioning the company to serve global automotive and electronics supply chains. Revenue figures are not publicly disclosed; the company is a privately held joint-stock corporation within the broader Changsung Group conglomerate, with registered capital of 483 billion KRW.
