Elgiloy
Corrosion-Resistant Super Alloy
Elgiloy® is considered a “super-alloy” consisting of cobalt, chromium, nickel, iron, molybdenum and manganese.
Grades / Attributes
Elgiloy is used to make springs that are corrosion resistant as well as provide high strength, ductility and good fatigue life. Elgiloy is highly resistant to sulfide stress corrosion cracking and pitting, and can operate at temperatures up to 850°F.
Spring Applications
Oil and gas in a wellbore environment is probably one of the largest applications for Elgiloy springs because the alloy is highly resistant to corrosion cracking in chlorides. It is also used in aerospace applications where high strength and temperature resistance is required. Other applications include springs for medical and dental products.
Material Benefits
Alternative material for Inconel X-750, if upgraded performance is required. Elgiloy will provide more strength in a small space than Inconel X-750 and MP35N.
Considerations
Cost can be prohibitive if the performance requirements do not merit its use.
Custom Elgiloy Springs
We manufacture custom Elgiloy springs from wire and strip material. With over three decades of experience, our expert team works with your engineers to review product drawings and control manufacturing so you get the Elgiloy spring you need, especially for difficult applications such as those that have severe service requirements. Our Elgiloy spring products include:
- Custom springs
- Compression springs
- Flat, bow, and drag springs
- Garter springs
In addition to Elgiloy springs, we also manufacture other Elgiloy components, such as Elgiloy Bellevilles, washers, and snap rings. We specialize in applications that have severe service needs.
