GENERAL CLAD / COPPER-CLAD STEEL
CCS 55% IACS
Copper-clad steel round wire in the 55% IACS conductivity class. Use this grade to begin a specification review with our team.
Confirm the current size, temper and performance specification before purchase. The grade number is not a copper-content percentage.
01 / CATALOG RECORD
A defined starting point.
This record identifies the 55% IACS round-wire grade. For a stranded or coated construction, specify the finished conductor separately and confirm its complete requirements.
| Conductivity designation | 55% IACS |
|---|---|
| Listed diameter range | 0.06–6.54 mm |
| Listed material conditions | Hard-drawn or annealed |
| Current supply specification | Confirm for the required diameter, condition and application |
Catalog information reviewed 3 October 2026. The listed range is not an approved matrix of all available combinations. Request a current datasheet for the exact wire under review.
02 / BEFORE A QUOTATION
What to specify
alongside 55% IACS.
Share the application, target quantity and drawing together with these four requirements.
Dimensions
Finished diameter, tolerance, surface and packaging.
Electrical requirement
Maximum DC resistance, conductivity basis and test temperature.
Material condition
Steel-core grade, temper, tensile strength and elongation.
Qualification
Copper-layer requirements, test methods and batch traceability.
03 / SUPPORTING DOCUMENTS
Evidence for the wire
you are evaluating.
Ask for a current datasheet and relevant test documentation for CCS 55% IACS at your required size and condition. A report for a different sample does not establish the performance of your order.
