Twistite® Magnet Wire
For superior performance and tighter control over twisted wire construction.
For those who use twisted magnet wire in the production of custom toroid, ferrite and recording head coils, specialty audio and R.F. transformers, Twistite Magnet Wire offers several advantages over other twisted magnet wire.
Manufacturing capabilities include:
- Up to 33 twists per inch on fine wire
- Twisting tolerance as tight as +/-1%
- Tightly controlled capacitance, inductance and impedance characteristics
- Up to 10 colors in some sizes for conductor identification
- Huge selection of insulations including NEMA MW1000 105 – 240°C; (single through quadruple film builds)
- Wide range of sizes: 16 through 52 AWG
- Wide variety of conductor materials: copper; silver, plated conductors; and specialty alloys

Four conductor 28 AWG heavy polynylon-155
