Nimonic
Te Whakamahana Teitei
◆ Ko te Nimonic90 he kaha te kaha me te ngokingoki, he pai te aukati i te waikura me te aukati waikura, he pai hoki mo nga kopae turbine, matatahi me nga whakamaarama teitei o nga miihini hiko.
◆ Nimonic91 he kaha nui me te mahi anti-oxidation i te teitei o te pāmahana o 650-1000 ° C, a he pai mo nga waahanga teitei-nui penei i nga miihini aero-engine, nga miihini roketi, me te mana karihi.
