NIMONIC® alloy 75 yog 80/20 npib tsib xee-chromium alloy nrog tswj kev ntxiv ntawm titanium thiab carbon.Ua ntej tshaj tawm hauv xyoo 1940s rau turbine blades nyob rau hauv tus qauv Whittle dav hlau tshuab, tam sim no feem ntau yog siv rau daim ntawv thov hu rau oxidation thiab scaling kuj ua ke nrog nruab nrab lub zog ntawm kev khiav hauj lwm kub.Nws tseem yog siv rau hauv cov roj turbine engineering thiab tseem siv rau kev lag luam thermal ua, cov khoom siv hluav taws xob thiab cov khoom siv kho cua sov.Nws yog yooj yim fabricated thiab welded
