Nickel Alloy Nimonic 105
NIMONIC 105 (W. Nr. 2.4634) is a wrought nickel-cobalt-chromium-base alloy strengthened by additions of molybdenum, aluminum and titanium. It has been developed for service up to 950°C, and combines the high strength of the age-hardening nickel-base alloys with good creep resistance.
NIMONIC 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.

Nimonic 105 Annealing:
Nimonic 105 can be solution heat treated at 1149°C --C (2100°C --F) and then cooled in air.
Nimonic 105 Heat Treatment:
Nimonic 105 can be heat treated in 4 four steps.The steps are as follows:
- Solution annealing for 4 h at 1149--C (2100--F) followed by air cooling.
- Heating for 16 h at 1056--C (1925--F) followed by air cooling.
- Heating for 16 h at 849--C (1560--F).
- Air cooling to reach precipitation-hardening.
Nimonic 105 Applications:
