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 uzluksiz ish harorati: 1250ºC.
Erish harorati: 1500ºC
Elektr qarshiligi: 1,35 ohm mm2 / m
Ushbu turdagi fekral qotishma sim odatda sanoat pechlari va elektr pechlarida isitish elementlari sifatida keng qo'llaniladi.
Tophet qotishmalariga qaraganda kamroq issiq quvvatga ega, ammo erish nuqtasi ancha yuqori.
