Flat Wire
Copper Flat Wire for Coils and Windings
Copper flat wire provides a rectangular current path for coils, transformers and compact electrical assemblies. Specify width, thickness and corner radius together with the copper grade, temper and insulation needs. These details determine how the wire fits and bends in the winding.
Construction and specification
- Material construction
- Specified copper grade and temper
- Product form
- Flat wire
- Tolerance
- Precision rolling tolerance available on request
- Surface
- Bare, plated, annealed, insulated-ready
- Supply format

Selection and processing
For a catalog dimension reference, see copper flat wire. Define the corner radius and finished insulation dimensions in addition to metal width and thickness. The drawing determines fit, bend direction and the winding clearances.
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 is copper flat wire?
copper flat wire is a rectangular or ribbon-shaped conductor made by precision rolling or drawing, used where space utilization, heat dissipation and winding efficiency are important.
Why use copper flat wire instead of round wire?
Flat wire can improve slot fill factor, contact area, thermal path and packing density compared with round wire in motors, coils, transformers and power components.
Which drawing details are needed for Copper Flat Wire for Coils and Windings?
Width, thickness and tolerances. Corner radius, edge condition, camber and twist. Metal grade and temper. Surface finish or coating, joining method and inspection requirements. Quantity, spool or coil format, packaging and delivery destination.
