Tungsten Etching for Sensitive Applications
Elcon etches tungsten to produce critical components for use in defense, medical, aerospace and other markets. Tungsten is a refractory metal with the highest melting point of any element, 3422°C. This extremely high melting point combined with tungsten’s high tensile strength make it an ideal material for a wide range of sensitive applications, including surgical tools, electron guns and radiation shields. Due to its density, high strength and brittleness at room temperature, tungsten can be very difficult to CNC machine, making chemical etching the preferred process for fabrication of thin parts.
Elcon is the only etching manufacturer on the US west coast that is ISO9001-2015, AS9100D, and ITAR-certified.
