What materials are used in custom electromagnetic coils?
Custom electromagnetic coils can be manufactured using a variety of conductor, insulation, and encapsulation materials depending on the electrical, thermal, mechanical, and environmental requirements of the application. Most often, the conductor is a copper magnet wire, though specialized applications may utilize aluminum magnet wire, silver-plated copper wire, silver wire, or nickel-plated copper wire.
Coil designs often incorporate various insulation materials, tapes, coatings, bobbins, encapsulation compounds, and housings to provide protection from heat, moisture, vibration, chemicals, and mechanical stress.
