NIMONIC® daawaha 75 waa 80/20 nikkel-chromium alloy oo lagu daro titanium iyo kaarboon kontaroolan.Markii ugu horeysay ee la soo bandhigay 1940-meeyadii loogu talagalay marawaxadaha marawaxadaha ee nooca matoorada Whittle jet, hadda waxaa inta badan loo isticmaalaa codsiyada xaashida ee ku baaqaya oksaydheynta iyo iska caabinta miisaanka oo ay weheliso xoog dhexdhexaad ah heerkul sare oo shaqeynaya.Waxaa weli loo isticmaalaa injineernimada marawaxadaha gaaska iyo sidoo kale habaynta kulaylka warshadaha, qaybaha foornada iyo qalabka daaweynta kulaylka.Si diyaar ah ayaa loo hindisay oo loo alxanayaa
