UDIMET® alloy R41
UDIMET® alloy R41 (UNS N07041) is a precipitation- hardenable nickel-chromium alloy containing significant amounts of cobalt and molybdenum, along with lesser amounts of aluminum and titanium. Alloy R41 exhibits extremely high room and elevated temperature mechanical properties. Excellent corrosion resistance and fabricability have led to wide usage in critical aircraft engine components such as nozzle partitions, turbine blades and wheels, combustion chamber liners and structural hardware.
The UDIMET alloy series are super alloys that have nickel or iron or cobalt as their base metal. Super alloys are known for their high-performance at extremely high temperatures or under high mechanical stress. Super alloys are subjected to special hardening techniques in order to achieve high performance at extreme conditions. Some of the commercially available UDIMET alloys are UDIMET alloys 188, 250, 520, 720, R41, L-605.
UDIMET® alloy R41 is a super alloy with nickel as its base metal. This alloy is hardened by precipitation. Along with nickel, other metals like cobalt, chromium, aluminum, molybdenum are added to this alloy. The temperature-mechanical properties of this alloy are very high. It is also corrosion resistant and easily fabricated.
