Flat wire is a precision-drawn metal wire with a rectangular or ribbon-shaped cross-section, used in various industrial sectors such as electronics, automotive, medical devices, and electromechanics.
Key characteristics
- Tight tolerances in width, thickness, and edge shape
- High straightness and consistent surface finish
- Rounded or sharp edges, depending on design
- Excellent winding and forming behavior
Materials
Typical flat wire materials include:
- Copper and copper alloys (e.g., CuZn, CuSn)
- Nickel silver
- Stainless steel
- Nickel-based alloys
Material choice depends on conductivity, strength, corrosion resistance, and soldering requirements.
Surface finishing
Available with various galvanic coatings:
- Tin
- Nickel
- Silver
- Multilayer systems (e.g. for soldering or whisker mitigation)
Applications
- Coils and magnetic components
- Flat conductors for flexible connections
- Contact springs and plug-in contacts
- Sensors and PCB assemblies
- Heating and resistance elements
Quality assurance
Flat wire is typically RoHS-compliant and manufactured with precise control of dimensions, surface finish, and mechanical properties, ensuring optimal processing in automated systems.
