Aloi fecralyn wrthwynebiad uchel ac aloi gwresogi trydanol. Gall aloi fecral gyrraedd tymheredd y broses o 2192 i 2282 F, sy'n cyfateb i dymheredd gwrthiant OA o 2372 F.
Fe'i defnyddir fel arfer mewn ffwrnais drydanol, hobiau top gwydr, gwresogyddion tiwb cwarts, gwrthyddion, trawsnewidydd catalytig, elfennau gwresogi ac ati.
