Age hardening kūikawā nickel-based alloy, kiʻekiʻe ikaika ikaika ma 1400-1600 ° F.Good kū'ē i oxidation hoʻohana 'ia i loko o ke kinoea turbine engine ma 1400-1600 ° F lewa.I ka 1150-1150 ° F, ʻoi aku ka ikaika o Waspaloy creep rupture ma mua o 718.
Ma kahi pālākiō o 0-1350 ° F, ʻoi aku ka maikaʻi o ka ikaika tensile wela no kahi manawa pōkole ma mua o 718 alloy.
