Tungsten Photo Etching

Tungsten is a free element that is known for its high melting point and remarkable robustness. It is a hard steel-grey metal that is difficult to work with and brittle in its raw form. Tungsten is an extremely dense metal with an extremely high melting point and is 71% heavier than lead. With its high tensile strength, tungsten is an ideal material for sensitive applications. Its high strength and density make it difficult to be cut by machines like CNC making tungsten photochemical etching the best process for fabrication. While it retains its hardness, tungsten becomes malleable when put through the etching processes making it easier to work or form.

Tungsten photochemical etching is a process that uses an acid to cut and create a design or image on the surface of the metal that is specific to each project. The process produces material that can withstand harsh environments both indoor and outdoor. Photochemical machining is capable of cutting tungsten into precision parts that can be as small as 0.0005 inches. This material is used in surgical devices, heaters, x-ray tubes, electron guns, radiation shields, CT scanners, and ID tags in implanted medical devices. Tungsten microchemical milling is used in a variety of industries including military, aerospace, telecommunications, medical, and electronics.

E-Fab works with a broad range of thicknesses of tungsten to create the ideal product every time. Our advanced tungsten etching services retain the integrity of the alloy without producing heat-affected zones or burrs. Our team of highly experienced representatives will help you find the best design for your specific projects. With two decades and counting under our belts, we pride ourselves on being your tungsten part supplier for all of your projects. As an industry leader in photochemical machining, we ensure each manufactured component meets your exacting requirements, even for tougher etching surfaces like tungsten.
