Ogulitsidwa ngati Nickel Alloy 718 ndi Inconel 7l8, aloyi 718 ndi yamphamvu kwambiri ya nickel-chromium. Aloyi yowumitsa zaka iyi imapereka kukana kwa dzimbiri ndipo imawonetsa mikhalidwe yomwe imapangitsa kuti ikhale yosavuta kugwira nayo ntchito popanga. Zina zofunika za Nickel Alloy 718 ndi Inconel 7l8 ndi:
- Kukana kwabwino kwa kupumula
- Ikhoza kupangidwa ngakhale zigawo zovuta kwambiri
- Amapereka kutentha kosiyanasiyana -423°F(-253°C) mpaka 1300°F(705°C)
- Kuthamanga kwambiri, kutopa, kukwawa, ndi mphamvu yosweka
- Gamma Prime analimbikitsidwa
- Kukaniza bwino kwa okosijeni mpaka 1800 ° F (980 ° C)
- Amapezeka muukali, okalamba, ozizira, kapena ozizira komanso okalamba
Chifukwa cha kuchuluka kwake kwapadera, aloyi 718 imadziwika ndi mafakitale osiyanasiyana ofunikira ndikugwiritsa ntchito kuphatikiza:
- Zida zamagetsi zamagetsi
- Matanki osungira a cryogenic
- Ma injini a jet
- Ma injini a rocket opangidwa ndi mafuta ndi zida zake
- Fasteners ndi zida zida
- Zida zamafuta a nyukiliya
- Hot extrusion tooling
- Pansi dzenje shafting ndi mphamvu bolting
Nickel Alloy 718 ndi Inconel 7l8 imakhala ndi faifi wopitilira 50% komanso zinthu zingapo zosiyanasiyana:
- Ndi 52.5%
- Fe 18.5%
- Kr 19%
- Cb+Ta 5.13%
- Mo 3.05%
- Ndi 0.9%
- Al .5%
