Photo Etching Tungsten for Medical Applications
Tech-Etch specializes in the photo chemical etching of tungsten. Because tungsten is extremely dense, 71% heavier than lead, it is used in medical applications, which include grids used to collimate and attenuate stray x-rays in CT scanners, as well as ID tags used in implanted medical devices. Tungsten is also well known for retaining its strength at high temperatures. For that reason, it is used in applications such as filaments in vacuum and x-ray tubes. Tech-Etch also produces component parts made from several other specialty metals used in the medical device marketplace. These include titanium, niobium, elgiloy, MP35N, and nitinol. Parts range in thickness from 0.0005 in. and up. While providing quick turnaround and low tooling costs, photo etching produces burr-free parts with intricate and complex shapes. Designs can be proved in preproduction quantities without having to commit to expensive tooling. Laminating, plating, heat treating, and assembly are available in house.
