Copper Clad Aluminum Conductors
Copper-Clad Aluminum Flat Wire
CCA flat wire combines an aluminum core with copper cladding in a rectangular section. It is an option for coils and compact conductive parts where lower conductor weight matters. Compare the finished winding resistance, available space and connections when selecting it against copper.
Construction and specification
- Material construction
- Aluminum core with copper cladding; specify the layer ratio and its mass or volume basis
- Product form
- Flat wire
- R-angle precision / R
- ±0.01 mm
Selection and processing
Set width, thickness, corner radius and bend direction around the winding window. Compare copper and CCA at the required finished resistance. Include whether the supply request concerns bare conductor or an insulation process; the insulation build changes the finished section.
Standards context
Use the drawing and a material/form-specific purchase specification. Round-wire references do not qualify rolled strip, foil or flat wire. Confirm edition, methods and acceptance criteria.
