Wirerod｜Copper & Copper Alloy Products MITSUBISHI MATERIALS

Characteristics

The rod is produced by the SCR process, resulting in fewer surface defects and excellent drawability.
The drawn wire is manufactured using high-quality copper rod as the base material.
We can accommodate a wide range of grades and sizes, including tough pitch copper, various copper alloys, and oxygen-free copper wire (ROX®).

ROX®
Mitsubishi Materials Corporation 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.

Products Type

Copper rough-drawn wires in various diameters and alloys also available.
