ʻO GH907 kahi Fe-Ni-Co precipitation e hoʻopaʻakikī i ke ana wela kiʻekiʻe me ka hoʻonui haʻahaʻa a me ka deformation, 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 kokoke mau modulus o ka elasticity ma lalo o 650 ° C. Aia ka lae Curie ma waena o 400°C a me 4000°C. He haʻahaʻa ka hoʻonui haʻahaʻa o ka alloy a me ke kūpaʻa maikaʻi i ka luhi wela a me ke anu. Aia ka lae Curie ma kahi o 400 ℃-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 nā mea chromium a me aluminika, ʻaʻole maikaʻi ka pale ʻana o ka wela wela. Ke hoʻohana ʻia no ka manawa lōʻihi ma luna o 700 ° C, pono e hoʻopili ʻia nā pale pale kūpono. Hiki ke pana ʻia ka ʻili o ka alloy, kahi e hoʻomaikaʻi ai i ka luhi kuʻi ʻana ma kahi o 18%.
