Description

18 AWG Copper Magnet Wire Spool (Approximately 1800 feet} NOS

18 AWG (American Wire Gauge) copper magnet wire (also called enameled or winding wire) is a solid copper conductor coated with a thin layer of insulating enamel (typically polyurethane, polyamide, or similar). This allows tight winding without short circuits while enabling magnetic field generation.
 
Key Specs (Typical for 18 AWG Magnet Wire)
  • Bare conductor diameter: Approximately 0.0403" (1.024 mm) nominal.
     
     
  • Overall diameter (with insulation): Often ~0.0415" to 0.0437" depending on single or heavy build.
     
     
  • Length on  9 lb spool: ~1,800 feet
  • Resistance: ~1.27–1.64 ohms per pound or ~6.4–6.5 ohms per 1,000 ft (at 20°C).
     
     
  • Temperature rating: Common ratings are 155°C (311°F) or 200°C (392°F) for heavy-build enamel — your NOS spool is likely in this range.

  • Material: High-purity copper (often 99.9%+), enameled for insulation. Solderable at high temperatures after scraping or burning off enamel.

Common UsesMagnet wire excels in applications needing tightly wound coils for electromagnetic fields:
 
  • Motors & Generators: Rewinding or building small to medium electric motors, alternators, DC motors, power tools, and wind generators.
  • Transformers & Inductors: Power supplies, voltage converters, audio transformers, and electronic coils.
  • Electromagnets & Solenoids: Custom electromagnets, relays, valves, and scientific experiments.
  • Speakers, Headphones & Pickups: Voice coils, guitar pickups, and audio equipment.
  • DIY/Hobby/Science Projects: Tesla coils, crystal radios, electromagnets for education/kids' projects, electroculture gardening, invisible wiring for LEDs/displays, and homebrew electronics.
  • Other: Repair of electrical equipment, custom inductors, antennas, and high-temperature winding applications (depending on enamel rating).  Antenna wire or ground radials.
