Fekral qotishma sim (CrAl 23/5) elektr isitish simi
Fekral qotishma sim (CrAl 23/5)
Nominal tahlil
23.00 Cr, 5.00 Al, Bal. Fe
Maksimal doimiy ish harorati: 1250ºC.
Erish harorati: 1500ºC
Elektr qarshiligi: 1.35 ohm mm2/m
Ushbu turdagi najasli qotishma sim odatda sanoat pechlarida va elektr pechlarida isitish elementlari sifatida keng qo'llaniladi.
Tophet qotishmalariga qaraganda kamroq issiqqa chidamlilikka ega, ammo erish nuqtasi ancha yuqori.
