History of Sakai Plant

 Characteristics

Wirerod manufactured at Sakai Plant utilizing the SCR system is used for applications such as electronic wire, magnet wire, and trolley wire due to its high purity and almost flawless surface. The plant is not only capable of manufacturing tough-pitch copper, but also other copper alloys and ROX® (Oxygen-free copper wire rods).
ROX®
Sakai Plant succeeded in manufacturing oxygen-free copper wirerod utilizing the SCR system for the first time in the world. Previously, oxygen-free wirerod wire and oxygen-free copper metals were manufactured using DIP forming or Extrusion. However, thanks to the SCR system, we can incorporate all manufacturing processes from melting to the finished wirerod in one continuous operation.
