21 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.
