Flat Wire
Flat Wire for Coils and Electrical Parts
Flat wire provides a rectangular conductor section for coils and compact electrical parts. Compare copper, aluminum and clad options by finished resistance, weight, forming and connections. Specify width, thickness, corner radius and surface condition for the part or winding.
Construction and specification
- Material construction
- Specify the conductor metal, grade and layer construction on the drawing
- Product form
- Flat wire
- Tolerance
- Precision rolling tolerance available on request
- Surface
- Bare, plated, annealed, insulated-ready
- Supply format
- Coils, spools or cut lengths
Selection and processing
Flat and rectangular wire describe the section; ribbon wire generally denotes a thin, narrow flat section. Compare material choices at the required resistance, winding space and joint design. The drawing defines the aspect ratio and corners rather than a universal maximum ratio.
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 flat wire?
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 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 Flat Wire for Coils and Electrical Parts?
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.
