CCA and Copper Flat Wire for Windings
Compare both materials within the available winding space. Set the resistance target, then check width, thickness, corner radius, insulation allowance and bend geometry. Assess the finished coil and its connections before comparing weight and manufacturing cost.

| Decision | CCA flat wire | copper flat wire | Acceptance basis | Your input or result |
|---|---|---|---|---|
| Flat geometry | Copper-clad aluminum section with defined width, thickness and corner radius | Copper section with defined width, thickness and corner radius | Specify camber, twist and measurement method after forming. | |
| Winding space | Layer ratio and section affect resistance and bend response | Copper grade, temper and section affect resistance and bend response | Compare equal resistance within the available winding space. | |
| Edges and joints | Check cladding continuity at corners, bends and cut ends | Check copper surface and formed edges | Qualify joining with actual flat-wire tooling; round-wire references do not qualify the rolled form. | |
| Cost basis | Include forming, section change and rejected windings | Include copper section, forming and rejected windings | Compare cost per accepted winding; obtain drawing-owner approval for a copper substitution. |
