Gwifren Alloy Fecral (CrAl 23/5) gwifren gwresogi trydan
Gwifren Alloy Fecral (CrAl 23/5)
Dadansoddiad Enwol
23.00 Cr, 5.00 Al, Bal. Fe
Tymheredd gweithio parhaus uchaf: 1250ºC.
Tymheredd Toddi: 1500ºC
Gwrthiant Trydanol: 1.35 ohm mm2/m
Fel arfer defnyddir y math hwn o wifren aloi fecral yn helaeth fel elfennau gwresogi mewn ffwrneisi diwydiannol ac odynau trydanol.
Mae ganddo lai o gryfder poeth nag aloion Tophet ond ymdoddbwynt llawer uwch.
