ʻO ka Incocoloy 901 he nickel-iron-chromium alloy i loaʻa ka titanium a me ka alumini no ka paʻakikī o ka ua a me ka molybdenum no ka hoʻoikaika paʻa.He kiʻekiʻe ka ikaika a me ke kūpaʻa ʻana o ka alloy ma kahi o 1110°F (600°C).Hiki i ka mea hao ke hoʻohui i ka ikaika kiʻekiʻe me nā ʻano forging maikaʻi.Hoʻohana ʻia i nā turbine kinoea no nā disc a me nā shafts.
