Our filaments are made in house using proven fabrication processes and are of the highest quality, reliability and consistency in the industry. The benefits of using tungsten metalizing filaments for your evaporation process include low cost, long life, high rates with low power, repeatability and ease of use. Custom fabrication is available upon request. Images shown are for reference only. Actual parts may look different based on the type of wire selected.
