Nimonic fasteners are best known for their high temperature, low-creep attributes. They are comprised primarily of nickel and chromium – typically more than 50% nickel and 20% chromium – along with other additive such as titanium and aluminum. Due to their ability to withstand extreme temperatures and pressure, they are often used in aircraft parts and gas turbine exhaust applications as well as high temperature furnace applications. Nimonic fasteners are available in two different alloy grades with slightly different capabilities.
