I-Metal Foam iyinhlanganisela yensimbi ekhethekile enezimbobo zomoya we-foam. Ngokwezici zayo ezihlukile zesakhiwo, insimbi yegwebu inochungechunge lwezinzuzo ezinhle kakhulu njengokuminyana kwesihlobo esiphansi, ukumelana nomlilo okuhle, umsindo omuhle nokusebenza kokunciphisa umsindo futhi ingagaya futhi imunce amaza omsakazo, njll. Isigaba esisha sezinto zokwakha kancane kancane. ithuthukiswa kanye nenkambiso yabantu yokuthuthukiswa kobuchwepheshe obuphezulu evame ukusetshenziswa endaweni yezindiza, imishini ye-petrochemical kanye nochungechunge lomklamo wokuthuthukiswa kokukhiqizwa kwezimboni.

I-Porosity
I-Porosity isilinganiso sevolumu yawo wonke ama-porosity emzimbeni wesakhiwo esinezimbotshana ukuya kumthamo ophelele womzimba wesakhiwo esinezimbotshana, ngokuvamile kucatshangelwa ubukhulu besikhala esiphakathi nendawo somzimba wesakhiwo esinezimbotshana.
I-porosity ye-foam yensimbi ivame ukufeza ngaphezu kuka-90%, futhi inamandla athile okucindezelayo nokuqina okugoba kwezinto zensimbi zesakhiwo se-porous. Lolu hlobo lwensimbi lune-porosity ephezulu, futhi ububanzi be-porosity bufinyelela ezingeni le-mm.
