Elgiloy Chemical Etching
Elgiloy is considered a superalloy that consists of 39-41% Cobalt, 19-21% Chromium, 14-16% Nickel, 11-20% Iron, 6-8% Molybdenum, and 1.5-2.5% Manganese. This compound mixture allows Elgiloy to be a high strength, high fatigue, corrosion, cracking, and pitting resistant material. With these qualities, Elgiloy chemical etching is common for medical, aerospace, and defense.
Elgiloy Chemical Etching
Fotofab’s etching process produces designs that can withstand harsh indoor and outdoor environments. The process uses a strong caustic chemical to etch into unprotected parts of a metal surface to create a design or image formed to your project’s specifications.
Characteristics of Elgiloy
Elgiloy is resistant to sulfide stress corrosion, cracking, and pitting. It can operate at temperatures up to 850°F (454°C). Other characteristics include:
- High melting point (2601°F) and operates in heat up to 850°F
- Ductile
- Fatigue resistant
- High tensile strength of 141000 psi
- Yield strength of 69600 psi
- Non-magnetic

Acid Etched Elgiloy Service Applications
This super-alloy is popular for springs that are corrosion resistant, strong, ductile, and have good fatigue life. Other applications include:
- Semiconductor components
- Surgical implants
- Satellite communications equipment
- Weapon systems
- Medical devices
- Seals
- Aerospace components that require high strength and temperature resistance
Other Factors
- Elgiloy provides more strength in a small space than Inconel X-750 and MP35N
- It is recommended that forming be done before heat treatment as heat treatment strengthens Elgiloy and make it difficult to form afterward
- Meets specifications of AMS 5876, AMS 5833, and UNS R30003
- Elgiloy is also known as Phynox Cobalt-Chromium-Nickel
