CCA and Aluminum: Compare the Conductor and Joint
Compare the materials at the required resistance and available space. CCA adds a copper surface to an aluminum core, which changes the connection options and material balance. Include conductor size, terminal design and joining cost when comparing finished assemblies.

| Decision | Copper Clad Aluminum (CCA) | Pure Aluminum | Acceptance basis | Your input or result |
|---|---|---|---|---|
| Construction | Aluminum core with a copper surface | Specified aluminum grade through the section | State CCA copper ratio and the base aluminum grade. | |
| Electrical design | Composite section is sized to the resistance target | Aluminum section is sized to the resistance target | Compare length, temperature and available space before mass. | |
| Connection | Copper surface changes the contact construction | Aluminum surface requires its specified connection process | Use the actual terminal and joint; a copper surface alone does not approve a copper terminal. |
