Dufrane is an industry leader in the design and manufacture of custom electric coils and custom windings of all types, due to our custom winding capabilities.

Custom windings and coils can be designed or build to print, for use in such applications as relays, antennas, electromagnetic devices, solenoids, electromagnetics, sensors, microphones, speaker assemblies, in industries such as medical, robotics, measurement, defense and aerospace, transportation and many more.

Dufrane primarily uses copper, aluminum, or copper clad aluminum wire for its custom coils and windings. Copper wire is preferred for its superior conductive properties, in most cases. Aluminum wire can be substituted for weight-sensitive applications, or copper clad aluminum (CCA) wire can be used to reduce mass while retaining copper’s ease of soldering.

We work with inner diameters from 0.062” and tolerances are held to as tight as ±0.001” for smaller coils and ±0.003” for larger coils. Wire used in our custom coils and custom windings include several additional processes as necessary.

Dufrane also serves as a contract manufacturer and can negotiate effective blanket orders as well as maintain inventory on raw materials or even finished product on any customer part numbers.
