31 AWG Solid Bare Copper Hard Medium Soft Drawn Wire

About:

• The solid bare copper wire is a thin, single strand of copper that is uninsulated and typically used in delicate or high-precision electrical applications. Available in hard drawn, medium drawn, and soft drawn forms, it offers different levels of tensile strength and flexibility based on the intended use.

Also Known As:

• Thin Solid Copper Wire
• Bare Copper Ground Wire
• Fine Copper Wire
• Precision Copper Wire

Application:

• For use in electrical grounding systems, and on insulators for overhead transmission and distribution applications.

Standard:

• ASTM B1: Hard-Drawn Copper Wire.
• ASTM B2: Medium-Hard Drawn Copper Wire.
• ASTM B3: Soft or Annealed Copper Wire.
• RoHS Compliance: Meets restrictions on hazardous substances.

Construction:

• Material: 99.9% pure copper.
• Shape: Solid round wire.
• Surface: Smooth, clean, and free of defects to ensure consistent performance.

Features:

• Exceptional Conductivity: Provides excellent electrical conductivity, making it suitable for high-frequency and low-power applications.
• High Precision: Manufactured to tight tolerances for critical applications.
• Corrosion Resistant: Copper’s natural resistance to corrosion ensures long-lasting performance.
• Thermally Stable: Performs reliably across a wide temperature range.
• Solderable: Easy to solder, providing strong, stable connections.
