Product Description

POLYURETHANE INSULATED COPPER WIRE 0.25MM ENAMELED COPPER WIRE NATURE COLOR

Magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductors, motors, speakers, hard disk head actuators, electromagnets, and other applications that require tight coils of insulated wire.The wire itself is most often fully annealed, electrolytically refined copper. Aluminium magnet wire is sometimes used for large transformers and motors. The insulation is typically made of tough polymer film materials rather than enamel, as the name might suggest.

FEATURES AND BENEFITS

  • Excellent dereeling and windability on high speed and / or automatic winding machines.

  • Produces compact coils and windings.

  • Superior "Q" characteristics at high frequencies.

  • Exceptional film flexibility and adhension.

  • Excellent resistant to a variety of solvents including most varnishes and hardener catalysts.
