FeCrAl qotishmasi 0Cr27Al7Mo2 yuqori issiqlik samaradorligi Alxrom qotishma qarshilik simi
FeCrAl qotishmasi 0Cr27Al7Mo2yuqori issiqlik samaradorligiAlxrom qotishma qarshilik simi (Ish harorati 1400C)
Nominal tahlil
27.00 Cr, 7.00 Al, 2.00 Mo, Bal. Fe
Maksimal uzluksiz ish harorati: 1400 C.
Tel diametri: 0,5 ~ 12 mm
Erish harorati: 1520 C
Elektr qarshiligi: 1,53 ohm mm2 / m
Sanoat pechlari va elektr pechlarida isitish elementlari sifatida keng qo'llanilgan.
Tophet qotishmalariga qaraganda kamroq issiq quvvatga ega, ammo erish nuqtasi ancha yuqori.
