CCA and CCS: Choose by Electrical and Mechanical Duty
Start with the required resistance, weight, strength and service conditions, then compare the aluminum-core and steel-core constructions against those requirements.
Engineering comparison
Fill in the input cells, then copy the table and paste it into your inquiry. Leave unknown items blank.
On narrow screens, scroll to see all columns.
| Decision | Copper Clad Aluminum (CCA) | Copper Clad Steel (CCS) | Acceptance basis | Your input or result |
|---|---|---|---|---|
| Core and surface | Aluminum core with copper cladding | Steel core with copper cladding | A shared copper surface does not make the cores interchangeable. | |
| Design priority | Compare mass, resistance and available section | Compare tensile/mechanical duty, resistance and section | Set the application duty first. | |
| Joining and exposure | Check layer continuity, cut edges and aluminum-core connection behavior | Check layer continuity, cut edges and steel-core connection behavior | Use the actual construction, terminal and environment. |
