ʻO GH907 kahi Fe-Ni-Co precipitation hardening haʻahaʻa hoʻonui deformation kiʻekiʻe wela alloy, hoʻoikaika ʻia me ka niobium, titanium, silicon a me trace boron. Loaʻa ka ikaika kiʻekiʻe o ka alloy, haʻahaʻa haʻahaʻa o ka hoʻonui ʻana, kūpaʻa maikaʻi i ka luhi wela a me ke anuanu a aneane mau ka modulus o ka elasticity ma lalo o 650 ℃. Aia ka lae Curie ma waena o 400 ℃ a me 450 ℃. ʻAʻole i hoʻololi ʻia ka coefficient o ka hoʻonui ʻana o ka alloy ma lalo o ke kiko Curie. He kūpono ka alloy no ka hana ʻana i nā ʻano like ʻole o ka mokulele a me nā mīkini aerospace a me nā mīkini ma lalo o 650 ℃, a ʻo nā huahana nui e pili ana i nā pahu, nā forgings, nā papa a me nā ʻāpana. No ka mea ʻaʻole i loaʻa i ka alloy chromium, nā mea alumini, ʻaʻole maikaʻi ke kūpaʻa ʻana o ka wela wela. Ke hoʻohana ʻia no ka manawa lōʻihi ma luna o 700 ℃, pono e lawe ʻia nā pale pale kūpono. Hiki ke pana ʻia ka ʻili o ka alloy, a hiki ke hoʻonui ʻia ka luhi kuʻi ʻana ma kahi o 18% ma hope o ka pana ʻana.

Ua hoʻohana maikaʻi ʻia ka huila i ka hana ʻana i nā makasina aero-engine kiʻekiʻe-pressure compressor hope, nā apo lawe ukana, nā apo wela wela, nā apo hoʻopaʻa ʻana o ke keʻena puhi, nā noho honeycomb a me nā apo waho turbine.
