MISUZU, a pioneer of rolling conductors

As digital devices become smaller and lighter, these conductors are thin and compact. From domestic electrical appliances to automobile airbags, flat copper wires (high rolling factor) play a vital role in carrying information.

  • As a pioneer of rolling conductors, we have won designations for FFC material from major consumer electronics, AV, and OA equipment manufacturers.
  • Patent for whisker measures has been published (ternary alloy). Revision from costly gold plating is advancing.
Flat copper wire
Example of use
  • FFC (Flexible Flat Cable)
  • Steering cable

Wide flat copper wire

By reducing the thickness of the wide flat wire, the bending characteristics will be improved.
It is mainly used for automobile airbags and batteries.
Currently, there is a demand for conductors with a width of 6 mm for lithium-ion electrodes.
