Spherical jan karfe foda yana da low porosity da dangi zamiya gogayya factor, mai kyau expandability da ductility.Ultrafine jan karfe foda yana da abũbuwan amfãni daga cikin manyan takamaiman yanki, aiki mai karfi, babban ma'anar narkewa, mai kyau magnetism, lantarki da kuma thermal conductivity, mai kyau haske sha da sauran abũbuwan amfãni, kuma yana da fadi da aikace-aikace a da yawa filayen.

Ana amfani da foda mai siffar micron don gudanar da wutar lantarki:
