Tungsten Photochemical Etching

Tecomet has over 20 years' experience providing high-caliber etching for the medical, aerospace, and technology industries. Our robust photochemical machining and tungsten etching capabilities ensure that each manufactured component meets the most exacting requirements, even on hard-to-etch surfaces like tungsten and other specialty metals.

Tungsten Etching Capabilities

Tungsten's unique characteristics make it a desirable specialty metal for implants, springs, electrodes, and stents. Advantages of using tungsten for medical etching include:

• Corrosion resistance
• High density – 70 percent greater than lead
• Biocompatibility
• High radiopacity
• High tensile strength
• High melting point
• Low vapor pressure

Tungsten Etching Applications

Tungsten is an inert material ideal for precision parts as small as 0.0005 inches and used by medical manufacturers and OEMs for CT scanner grids and implanted medical device ID tags. High tensile strength and density make tungsten useful for guidewires and probes, while excellent performance at extreme temperatures makes it a vital component in rocket engine nozzles and heating elements. 

Tecomet deals with a broad range of tungsten thicknesses and shapes across industries, and can etch tungsten as low as 0.001 inches and as high as 0.080 inches. Our high-tech photochemical etching processes retain the integrity of the remaining alloy without producing burrs or heat-affected zones. We have extensive experience in the aerospace and defense industries. Our etching facilities are DFARS compliant and ITAR compliant, ensuring that your aerospace or defense industry project is secure from start to finish.
