Mpweya Woumitsa Chitsulo Chosapanga dzimbiri
High Temperature Alloy
◆0Cr17Ni7Al ndi chitsulo chowumitsa mpweya ndi Al wowonjezera, wogwiritsidwa ntchito ngati akasupe, ochapira, zigawo zowerengera, ndi zina zotero.
◆0Cr15Ni7Mo2Al imagwiritsidwa ntchito pazotengera zamphamvu kwambiri, magawo ndi zida zomangika zomwe zimakhala ndi zofunikira zina zokana dzimbiri.
◆ Ntchito ya 0Cr15Ni5Cu4Nb ikufanana ndi ya 0Cr17Ni4Cu4Nb, koma imakhala ndi ntchito yabwinoko.
◆0Cr12Mn5Ni4Mo3Al (Gangyan 69111) ili ndi pulasitiki yabwino kuposa 0Cr15Ni7Mo2Al.
◆0Cr17Ni4Cu4Nb Mpweya woumitsa chitsulo ndi Cu wowonjezera, womwe umagwiritsidwa ntchito kwambiri muzitsulo, zigawo zamphamvu kwambiri zomwe zimafuna kukana kwa dzimbiri kwa ziwalo za injini ya nthunzi.
◆XM-25 ndi kutentha ndi kutentha kwambiri, koyenera ku petroleum, mankhwala, mlengalenga, mphamvu za nyukiliya ndi mafakitale ena.
