Copper Clad Aluminum Conductors
Copper-Clad Aluminum Foil
CCA foil has copper cladding on an aluminum core in a thin rolled form. For transformer and inductor windings, select the foil section around the required resistance, winding space and joining method. Include edge quality, surface finish and roll format in the specification.
Construction and specification
- Material construction
- Aluminum core with copper cladding; specify the layer ratio and its mass or volume basis
- Product form
- Foil
- Surface roughness /
- ≤0.2 μm
Selection and processing
Define the total foil gauge and each copper layer separately. For a roughness requirement, state Ra or Rz, the measurement method and direction. Edge burr, winding tension, bend and termination requirements need the actual coil layout.
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.
Standards scope referencesProduct questions
What should I send for Copper-Clad Aluminum Foil supply information?
Width, thickness and tolerances. Edge condition, burr, surface and roll dimensions. Core and outer-layer metals, each layer or ratio, and mass or volume basis. Surface finish or coating, joining method and inspection requirements. Quantity, spool or coil format, packaging and delivery destination. This identifies the construction and sample or production request to discuss.
What applications are relevant for CCA Foil?
CCA Foil is relevant for High-frequency transformer windings, PV and storage inverter inductors, Lightweight foil conductors and related engineered conductor applications where the material tradeoff is validated.
What information should be included in an RFQ for CCA Foil?
Include product form, dimensions, material ratio or layer requirement, target conductivity or strength, application environment, annual demand, packaging and any test or certification requirement.
