ABOUT UNION CITY FILAMENT
COMPANY HISTORY
Established in 1950, Union City Filament has been developing proprietary processes for winding and forming tungsten, molybdenum, rhenium and their alloys into a myriad of designs for nearly 70 years. Our processes make it possible for us to hold the tightest possible tolerances on dimensions and uniformity.
Union City Filament’s products are primarily designed to be electron or ion sources either through direct emission or by heating dispenser or oxide cathodes.
Today, our filaments are being put to use in the latest mass spectrometers and other analytical sensors, ion implanters, leak detectors, vacuum ionization gauges, getters, and specialty infrared applications.
Our heaters are installed in over 150 active US Department of Defense systems including the Patriot Missile and Aegis Combat System. Cathode heaters, manufactured at Union City Filament, provide essential fast warm-up capabilities and high reliability operation for microwave and millimeter wave devices that reside at the core of today’s most advanced military systems.
In addition, Union City Filament’s products are empowering traveling wave tubes for commercial communications space satellites, inductive output tubes for HDTV broadcasting, klystrons for radiation cancer therapy, x-ray tubes for CAT scanners, and magnetrons for marine, airborne, and weather radar.
We are constantly researching new uses for our products like handheld vaporizers and surgical tools. Regardless of what your end application is, Union City Filament’s expert engineers will work with you to design the best filament or heater to suit your needs.
