About Alloy
Nimonic 105 (W Nr, 2 4634) is a wrought nicke-cobalt-chromium-base alloy strengthened by additions of molybdenum, aluminum and titanium. it has been developed for serviceunto950' and combines the high strength of the age-hardening nickel-base alloys with good creep resistance. Nimonic alloy 105 is produced by high frequency melting in air followed by casting in air, or for more critical applications the alloy is produced by vacuum melting and electroslag refining, The alloy is used for turbine blades, discs forgings, ring sections bolts and fasteners.
