Isitishga qarshilik simi (CrAl14-4)
Nominal tahlil
13.00 Cr, 4.00 Al, Bal. Fe
Maksimal uzluksiz ish harorati: 950º C.
Erish harorati: 1450º C
Elektr qarshiligi: 1,25 ohm mm2 / m
Diametri 0,1 mm ~ 12 mm, sim, novda, spiral shaklida
Sanoat pechlari va elektr pechlarida isitish elementlari sifatida keng qo'llanilgan.
Tophet qotishmalariga qaraganda kamroq issiq quvvatga ega, ammo erish nuqtasi ancha yuqori.
