0Cr21Al4 ndi mtundu umodzi wa zinthu wamba za aloyi ya Fe-Cr-Al.

Aloyi ya FeCrAl ili ndi mawonekedwe a resistivity yapamwamba, coefficient yotsika kutentha, kutentha kwakukulu kogwira ntchito, anti-oxidation yabwino komanso anti-corrosion pansi pa kutentha kwakukulu.

Amagwiritsidwa ntchito kwambiri m'mafakitaleng'anjo, zipangizo zapakhomo, mafakitaleng'anjo, zitsulo, makina, ndege, magalimoto, asilikali ndi mafakitale ena omwe amapanga zinthu zotenthetsera ndi zinthu zotsutsa.

FeCrAl, banja la zitsulo zachitsulo-chromium-aluminium (Kanthal APM, A-1, D ndi AF etc.) zomwe zimagwiritsidwa ntchito m'njira zosiyanasiyana zotetezera komanso kutentha kwambiri zimagwiritsidwanso ntchito ngati mawaya otetezera.
Dzina: waya wotenthetsera
mtundu: okosijeni kapena kuwala
Phukusi: Katoni kapena bokosi lamatabwa monga momwe akufunira
Kugwiritsa ntchito: kupanga zida zotenthetsera monga ng'anjo yamafakitale, zida zotenthetsera zapakhomo, zotsutsana zamagetsi zosiyanasiyana ndi zotsutsana ndi mabuleki a locomotive

Kukula kwa kukula:
