3A Co., Ltd. (CEO Yong-sook Lee) has been prominent as an aluminum wire producer for more than 20 years by focusing on aluminum under the banner of "ACE, ALL, and ALUMINUM" since 1999. Based on the combined technology of copper and aluminum and know-how in microfiber processing through continuous research and development, has technology to reduce the thickness of any aluminum wire through wire drawing and heat treatment on meantime secures the required strength and specifications.

Aluminum Wire has a technology for processing wire materials of various alloys such as 10 to 80xx series, and CCA wire is a material based on light weight and economy by replacing copper with aluminum, and is used in coaxial cables for electric vehicles and wires.

3A started from specializes in processing aluminum and developed CCA, coated with aluminum on copper, and has recently produced and supplied aluminum battery terminals for secondary battery.

The feature of the 3A product is that it has secured uniform quality even at 0.1mm by increasing the machining precision of aluminum wire. Processing capacity through accumulation of experience and technology in the development of various aluminum alloys, and the unique production capacity and technology of domestic CCA, It is expanding its product areas to insect screens, accessories, and Busbar and has entered the electric vehicle winding market.CCA has obtained UL certification, expanded to process and supply materials for secondary battery connection terminals through aluminum roll pressing, and developed material technologies for industrial wires, electric vehicle motor windings, and UTP cables using CCA.

Based on these achievements, 3A is a star company with annual sales of 10billion Won and 30 employees, and has been growing into an aluminum company over the past three years, including exports to China and certified ISO 9001, 14001, root technology companies, material parts companies, and excellent technology evaluation companies.

3A representative mentioned “We developed electric vehicle windings using CCA through Mobiis and technology development in 2012, and we are focusing on developing windings in response to the revitalization of the electric vehicle market” and also mentioned as “We are trying to expand the export market by developing new products for market expansion, such as the development of high-strength and lightweight fasteners, and linking with overseas exporting companies. “

Meanwhile, Chungbuk Techno Park has prepared and focused on Chungbuk National Innovation Cluster TF since last year to strengthen the competitiveness of regional representative industries. The main content is to establish a national innovation cluster in Chungcheongbuk-do, enhance global competitiveness and lay new growth bases for local industries by  "intelligent high-tech parts industry"
