Alyaj INCONEL® 718 (UNS N07718/W.Nr. 2.4668) se yon materyèl kwòm nikèl ki gen gwo fòs, ki reziste korozyon yo itilize nan -423 degre jiska 1300 degre F. Limit konpozisyon tipik yo montre nan Tablo 1. Laj la. -alyaj hardenable ka fasilman fabrike, menm nan pati konplèks. Karakteristik soude li yo, espesyalman rezistans li nan fann postweld, yo eksepsyonèl. Fasilite ak ekonomi ak ki INCONEL alyaj 718 ka fabrike, konbine avèk bon rupture, fatig, ranpe, ak fòs rupture, te lakòz itilizasyon li nan yon pakèt aplikasyon. Egzanp sa yo se konpozan pou fize likid, bag, anvlòp ak divès kalite pati tòl ki fòme pou avyon ak motè turbine gaz ki baze sou tè, ak tankaj kriyojenik. Li se tou itilize pou Fastener ak pati instrumentation.
