Tungsten Filaments are made using proven fabrication processes and are of the highest quality, reliability and consistency in the industry.
Multi-strand filaments are generally preferred because they offer a greater surface area than single-wire filaments. Because of their simplicity and low cost, wire sources are also used to evaporate metals such as Al, Ni, Fe, or Pt which are known to alloy with Tungsten.
Under these conditions, the evaporant charge should be small compared with the mass of the filament, and the latter is quickly destroyed if the molten evaporant collects in one spot.
Custom fabrication is available upon request.
