Copper Clad Steel Conductors
Copper-Clad Steel Round Wire
CCS round wire combines a steel core with copper cladding. Select the conductor by its tensile requirement, conductivity grade and copper-layer specification. For grounding, include fault-current duty and corrosion conditions; for signal cable, include frequency and cable construction.
Construction and specification
- Material construction
- Steel core with copper cladding; specify core grade and conductivity grade
- Product form
- Round wire
- Strength target
- Specified by tensile strength, steel core and application load
- Use environment
- Grounding, cable, rail, connector or high-vibration signal use
Selection and processing
Separate signal-cable and grounding duty. The signal design sets frequency and attenuation/resistance requirements; the grounding design sets fault-current duration, joints and environmental exposure. Core grade, condition and copper layer govern the single wire.
Standards context
ASTM B227-15(2024): hard-drawn bare round CCS wire; ASTM B452-22(2026): bare round CCS for electronic applications. Select the applicable grade, condition and purpose.
