Formula: Fe
Form: Insulated Wire
Material: Iron
CAS Number: 7439-89-6
Commodity: Metals
Insulation:
Polyimide
Polyimide Iron Insulated Wire is a product offered by Goodfellow within their wide range of specialty wires. This wire features an iron conductor surrounded by polyimide insulation. Polyimide provides excellent thermal stability and dielectric strength while remaining flexible. With 36 size variations, this wire can be customized for applications like magnet wire, transformers, electric motors, and other high temperature coil windings. The polyimide insulation enables operation at temperatures exceeding 220°C without compromising electrical performance.
