Deskripsyon materyèl:
Kontni an nikèl pi wo a gen ladan Cobalt. Kontni an fè se balans lan. Devlope nan kòmansman lane 1960 yo, IN718 toujou konsidere kòm materyèl la nan chwa pou pi konpozan motè avyon itilize anba a 1200 degre F (650 degre). Inconel 718 se yon presipitasyon-fè tèt di toujou alyaj nikèl-chromium ki tou gen kantite siyifikatif nan fè, niobyom, ak molibdèn, ak pi piti kantite aliminyòm ak Titàn. Li konbine rezistans korozyon ak gwo fòs ak ekselan weldability, ki gen ladan rezistans nan post-soude fann. Alloy a gen ekselan fòs kraze kraze nan tanperati jiska 1300 degre F (700 degre).
Aplikasyon: Aerospace, turbines gaz, motè fize, veso espasyèl, navèt espas, réacteurs nikleyè, ponp, sele turbopump, ak zouti.
Fòm: wonn, plat, fòm sòti, tib, tiyo, forgings, plak, fèy, teren, ak fil.
