Copper electrotechnical round wire

Usage

Copper electrotechnical round wire is destined for wire and cable production as well as for other electrotechnical purposes.

Follow grades wire is produced:

  • МТ – copper hard;
  • ММ – copper soft.
  • Wire is produced with effective diameter from 1.14 to 3.5 mm.
