Inconel is a family of austenitic Nickel-Chromium based alloys well suited for service in environments subjected to extreme pressures and temperatures. When heated, Inconel forms a thick and stable oxide layer that protects its surface from further attack. The alloy retains strength over a wide temperature range and exhibits high resistance to corrosion, oxidation, carburization, pitting and cracking. Common grades that Fotofab etches include Inconel 600, 718 and 750.
Fotofab utilizes a chemical etching process to produce designs that can withstand harsh indoor and outdoor environments. The etching process uses an acid (Ferric Chloride) to cut into unprotected parts of a metal surface to create a design or image. Our etched projects can be machined and formed to your project’s specifications.
