Inconel 718 bụ ihe eji eji nickel eme ka mmiri zoo. Ọ ka na-egosipụta ike dị elu, ike dị ike na ike ọgbụgba ọkụ na oke okpomọkụ ruo 704 Celsius C. Oge mmeghachi omume nke afọ 718 dị nwayọ nwayọ, n'ihi ya ọ gaghị eme ka kpo oku na obi jụrụ n'oge annealing na ịgbado ọkụ. E jiri ya tụnyere ndị ọzọ nickel dabeere superalloys gbakwunyere na aluminom na titanium, 718 alloy nwere ezigbo ịgbado ọkụ arụmọrụ.

AMS5662 bụ steeti izizi nke 718 na ọnọdụ kachasị nro na klaasị AMS. Site na ọgwụgwọ okpomọkụ, AMS5662 nwere ike ịtụgharị n'ime AMS5663. E nwere ụzọ ọgwụgwọ abụọ dị ọkụ, otu nwere ike ịkwalite arụmọrụ mmetụta, na nke ọzọ nwere ike ibuli ike mgbagha na ike ọgbụgba.
