Mwazinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito pazaumisiri, zida zachitsulo pang'onopang'ono zimakhala zofunikira komanso zogwira ntchito chifukwa chazinthu zabwino kwambiri pazinthu zambiri monga zimango ndi njira. Kwa zida wamba, mabowo nthawi zambiri amawonedwa ngati zolakwika zamapangidwe, ndipo nthawi zambiri amakhala pakati pakupanga ming'alu ndi kukulitsa, zomwe zimabweretsa zovuta kapena zowononga pazinthu zakuthupi. Komabe, pamene chiwerengero cha mabowo muzinthu chikuwonjezeka kufika pamlingo wina ndikugawidwa nthawi zonse, kukhalapo kwa mabowowa kumapangitsa kuti zinthuzo zikhale ndi katundu wapadera, motero kupanga kalasi yatsopano ya zipangizo, zomwe zimatchedwa porous materials. Zida zamakono zopangira porous zimaphatikizapo mapulasitiki a porous, ceramics porous ceramics, porous zitsulo ndi zina zotero. Ambiri amakhulupirira kuti pamene porosity wa porous zipangizo ndi 40% 98%, akhoza kutchedwa zipangizo thovu. Chithovu chachitsulo ndi nthambi ya zinthu za thovu, ndipo kapangidwe kake kali ndi izi: kukula kokulirapo kwa pore, porosity yapamwamba, mphamvu yokoka yopepuka, yokulirapo yapamtunda, ndipo gawo lalikulu la mafupa a mauna ndi chitsulo.

Chithovu cha aluminiyamu ndi chitsulo chopangidwa ndi thovu chomwe chimagwiritsidwa ntchito kwambiri, chomwe chimapangidwa ndi mafupa a aluminiyamu ndi pores, ndipo ndi chinthu chatsopano chopangidwa m'zaka zaposachedwa. Monga zinthu zomangika, zimakhala ndi zolemetsa zopepuka komanso mphamvu zenizeni zenizeni: monga zida zogwirira ntchito, zimakhala ndi zinthu zosiyanasiyana monga porous, vibration damping, damping, mayamwidwe amawu, kutulutsa kutentha, kuyamwa kwamphamvu komanso chitetezo chamagetsi.
Ngakhale ntchito zosiyanasiyana zotayidwa thovu zakuthupi ndi lonse, koma makamaka kuganizira ntchito katundu wake zinchito, ndi kusewera katundu zinchito zotayidwa thovu nthawi zambiri pa ndalama zake mawotchi katundu. Momwe mungasinthire magwiridwe antchito a chithovu cha aluminiyamu ndikusunga kapangidwe kazinthu zabwino zamakina kwakhala njira yotchuka yofufuzira, njira yodziwika bwino ndi aluminiyamu thovu - zitsulo zopangidwa ndi zitsulo - monga "sandwich" aluminium thovu, ndiye mphamvu. Pazitsulo zachitsulo chapamwamba, thovu la aluminiyamu pakatikati pa kapangidwe ka masangweji. Njira zazikulu zopangira masangweji a aluminium thovu, mapanelo ophatikizika amaphatikiza kulumikizana ndi kuwotcherera.
