Union City Filament has been developing proprietary processes for winding and forming tungsten, molybdenum, rhenium and their alloys into a 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 keeps a large inventory of raw materials for the fabrication of our products. This allows us to quote shorter lead times and control production costs. We only source raw materials from a handful of highly curated producers, of which we have worked with for decades, ensuring only the finest ingredients are used to make our products. We are constantly researching new uses for our products like handheld vaporizers and surgical tools.
