Qondisa ukuthuthukiswa kobuchwepheshe besimanje benqubo, okwenza ubuchwepheshe bokulungiselela i-foam metal buqhubeke buphelele, futhi izindleko zokukhiqiza ziyancipha ngokuqhubekayo. Insimbi enegwebu emelwe i-aluminium enegwebu iwuhlobo olusha lwezinto ezisebenzayo zesakhiwo oluthuthuke ngokushesha eminyakeni yamuva. Njengempahla yesakhiwo, inezici zesisindo sokukhanya namandla athile aphezulu. Njengento esebenzayo, igwebu le-aluminium linezinzuzo zokumuncwa ukushaqeka, ukumuncwa ukushaqeka, ukumelana nezinga lokushisa eliphezulu, ukugqunywa komsindo nokumuncwa komsindo.
Izimbotshana zangaphakathi zegwebu le-aluminium elivaliwe ligcwele igesi elinamandla amancane okudlulisa ukushisa, okwenza amandla ayo okudlulisa ukushisa abe mancane kakhulu kunezinto eziqinile. Igwebu le-aluminium elisebenzisa iseli linendawo enkulu ethize, i-porosity ephezulu, indawo ebanzi yokusabalalisa ukushisa kanye nokudlulisa ukushisa kwembotshana ephezulu, okukunikeza ukusebenza okuhle kokushintshisana kokushisa. Ngaphansi kwesimo se-convection yemvelo, ukushintshaniswa kokushisa kungenziwa phakathi kokugeleza kwegesi noma uketshezi ezimbotsheni zensimbi eyigwebu njengegwebu le-aluminium eliphuma ngaphandle kanye nezindonga zalo zembotshana, ngakho-ke igwebu le-aluminium eliphuma emgodini liyinto enhle yokushintshanisa ukushisa noma impahla yokushisa ukushisa.
Phakathi nenqubo yokucindezelwa kwegwebu le-aluminium, inani elikhulu lomsebenzi lizoguqulwa libe amandla ngendlela yokuguqulwa, ukuwa, ukuphuka kanye nokungqubuzana okuhlangene kwamaseli e-aluminium foam, ngakho-ke igwebu le-aluminium lingakwazi ukumunca inani elikhulu lamandla omthelela wangaphandle. Igwebu le-aluminum linezici eziphezulu zokumanzisa, futhi inani lokudambisa legwebu elihlanzekile le-aluminium licishe liphindwe izikhathi ezi-5 kuya kweziyi-10 kune-aluminium. Ngokusebenzisa amandla amahle okumunca kanye nezakhiwo ezidambisayo zegwebu le-aluminium, ingenziwa ibe izinto ezinhle kakhulu zokumunca amandla nezinto zokumunca ukushaqeka, njengamabhampa ezimoto, amagiya okuhlalisa umkhumbi-mkhathi, amakheshi, amaphedi okuphepha okuthutha kanye namakhava okuvikela ukugaya anesivinini esikhulu. Ingafakwa kulayini, njll.
Ngenxa yamandla ayo amahle okudlulisa uketshezi, ukusebenza kokuncishiswa kokushisa kwegwebu lensimbi eliphuma emgodini kungafinyelela ngisho nokuhamba okushisayo kwe-matrix yayo eminyene. Ukusetshenziswa kwale nsimbi yegwebu kungathuthukisa izishintshisi zokushisa zemishini ye-aerospace, osinki bokushisa abahlangene bamandla wamandla nokupholisa umoya. Amandla okushintshanisa ukushisa kwemishini efana nemibhoshongo ejiyayo. Isibonelo, kudivayisi yokukhipha u-icing kanye nedivayisi evimbela ukuqhwa esetshenziswa endizeni, ipuleti le-aluminium eliyigwebu eliphuma emgodini lifakwa ngaphambi kwephiko, futhi igesi eshisayo noma isinqanda-qhwa sifuthwa kusuka kupuleti le-aluminium eliyigwebu ukuze kuzuzwe inhloso yokukhipha i-icing.
