Nungwon Metal Ind. (NWM) was established in 1986 primarily to supply tubes to its sister company, Jungwoo Fittings (JWM), while also serving customers throughout the Asian market.

In 2006, NWM acquired a second tube mill facility, bringing its combined production capacity to more than 70,000 MT and enabling NWM to produce a diverse range of products, including Level Wound Coils, Pancake Coils, Utility Coils, and Straight Lengths. NWM utilizes both the casting and rolling process and the extrusion process to manufacture copper tube products ranging from 4.76 mm to 307.98 mm (3/16" to 12 1/8" OD).
