Alloy 907 UNS N19907: An Overview
In the demanding world of high-performance engineering, materials that can withstand extreme conditions are paramount. Alloy 907 UNS N19907 stands out as a premier iron-nickel-cobalt superalloy engineered for exceptional low thermal expansion and high strength from cryogenic temperatures up to 650°C (1200°F). This unique combination of properties makes it a critical material in aerospace, precision instrumentation, and other advanced technological fields.
Key Material Properties and Characteristics
The defining characteristic of Alloy 907 is its controlled thermal expansion. It maintains nearly constant dimensions over a wide temperature range, a property essential for applications requiring dimensional stability. Furthermore, it offers excellent high-temperature strength, good fatigue resistance, and remarkable toughness at cryogenic temperatures. Its oxidation resistance is superior to many other low-expansion alloys, ensuring long-term reliability in harsh environments.
Primary Industrial Applications
Due to its specialized properties, Alloy 907 is indispensable in several high-tech sectors. Its primary use is in aerospace for jet engine components, such as seals, rings, and casings, where tight tolerances must be maintained despite thermal cycling. It is also crucial in precision measurement devices, laser systems, and optical platforms where dimensional stability is non-negotiable. Additionally, it finds application in cryogenic equipment and molds for composite material curing.
Technical Specifications and Data
Alloy 907 UNS N19907 is a precipitation-hardenable alloy. Its nominal composition includes iron (Fe) as the base, with significant additions of nickel (Ni) and cobalt (Co), along with niobium (Nb) and titanium (Ti) for strengthening. It conforms to standards such as AMS 5914 and is available in forms like bar, wire, sheet, and plate. Typical mechanical properties include a high tensile strength and yield strength at elevated temperatures, with detailed datasheets available from specialized suppliers.
