Nimonic 901 alloy is a time-hardened Ni-Fe-Cr superalloy with significant additions of molybdenum, titanium, and aluminum. Depending on end-use applications and customer specifications, the alloy production process may involve combinations of vacuum induction melting, vacuum arc remelting, and electroslag remelting. Typically used in gas turbine components such as disks, shafts, rings, casings, and seals, this alloy operates at maximum temperatures up to approximately 600℃ (1100°F).
The density of the alloy is ρ=8.14g/cm³.
