Tsarin ƙarfe na kumfa na musamman mai girma uku mai girma uku ya sa ya sami kyawawan halaye masu yawa waɗanda suka bambanta da kayan gargajiya, kamar:

1. high porosity: da porosity iya isa fiye da 98% na kusan cikakken permeable tsarin, a matsayin tace abu, kananan matsa lamba drop, high kwarara kudi, m permeability.
2. babban yanki na musamman: tare da porosity iri ɗaya, yana da mafi girman yanki na musamman idan aka kwatanta da sauran kayan da ba a so ba, har zuwa mita ɗaya a kowace gram ko fiye.
3. high porosity da uniform pore tsarin: da porosity ne fiye da 95%, uku-girma porous da permeable tsarin, kuma yana da kyau karfe ƙarfi, guda girma, da kayan ne m a nauyi, kuma yana da mafi girma iya aiki, kuma yana da kyau sha sauti, makamashi sha, electromagnetic garkuwa Properties.
4. yana da kaddarorin karfe: karfen kumfa za a iya yin shi da nickel, jan karfe, ƙarfe, ko kayan gami, daban-daban substrates suna da kaddarorin ƙarfe daban-daban, irin su mai hana wuta, ba mai guba ba, ba faɗuwa saura, sake yin amfani da shi, thermal conductivity, da dai sauransu, a fadi da kewayon aikace-aikace.
5. za a iya welded, sheared, matsi na bakin ciki, birgima da sauran kayan aiki na inji, yayin da kayan karfe za a iya sake yin amfani da su, wanda zai dace da kare muhalli da kuma tanadin farashi a lokaci guda.
