Musiyano mukuru uripo pakati pesimbi yakakandwa muinjini nesimbi yealuminium huremu uye kugona kwayo. Simbi yakakandwa: Inodzivirira kupisa kwakanyanya uye haikurumidzi kuchinjika. Kana injini yesimbi yakakandwa yapfekwa, zviri nyore kugadzirisa uye mutengo wayo wakaderera. Aluminium alloy yakareruka, inokurumidza kupisa, uye mainjini ealuminium akareruka anogona kuderedza huremu hweinjini pachayo uye kuita zvinangwa zvinochengetedza mafuta. Zvinhu zveinjini ikozvino zvakakamurwa kuita mhando mbiri. Imwe isimbi yealuminium uye imwe isimbi yakakandwa. Zvakanakira aluminum alloy ndezvekutibhuroko resirindayakareruka uye inogadzira kupisa kuri nani.
Chinhu chikuru chinobatsira pakureruka kwesimbi iyi ndechekuti inoshanda zviri nyore. Panyaya iyi, kana huremu hwayo hwakareruka, mafuta anodyiwa anodzikira. Chinhu chimwe chete chinobatsira pakureruka kwesimbi ndechekuti dzine simba rakawanda. Nemamwe mashoko, kune varidzi vemotokari vane zvinodiwa pakushanda kwepamusoro, injini yesimbi inogona kugadziriswa panzvimbo pealuminium alloy. Kutonhodza kwesimbi yealuminium kwakanaka kwazvo, uko kusingaenzaniswi nesimbi yesimbi. Simbi yesimbi ine simba guru rekudzivirira kuchinjika kwesimbi. Simbi yesimbi ine simba guru rekutakura zvinhu zvinopisa, uko kusingaenzaniswi nezvinhu zvealuminium alloy.
Kana tichienzanisa nesimbi yakakandwa, mutengo wepamusoro wezvinhu zvakagadzirwa nearuminiyamu ndiyo dambudziko guru. Panyaya yekusimba kwechimiro, kuramba ngura uye kuramba kupfeka, aruminiyamu yakaderera pane simbi yakakandwa. Zvakanakira zvezvinhu zvakagadzirwa nearuminiyamu mutengo wakaderera, mutengo wakaderera, maitiro ekugadzira akakura, simba resilinda uye kuramba kupfeka. Uye kuramba ngura kuri nani pane kwearuminiyamu alloy, uye ine simba riri nani reinjini. Zvakashata zvezvinhu zvakagadzirwa nearuminiyamu ndekuti mutsetse wekugadzira simbi yakakandwa unogara munzvimbo yakakura, unosvibisa nharaunda, tekinoroji yekugadzirisa yakaoma, mashandiro ekupisa haana kunaka, uye huremu hweinjini hwakanyanya kurema. Nekuda kwezvakanakira nezvakaipa zvezvose Differently, macylinders akagadzirwa nesimbi yakakandwa anogona kushandiswa zvakanyanya. Mazhinji mainjini edhiziri akagadzirwa nesimbi yakakandwa. Mamwe mainjini emotokari epamusoro anogona kushandisa zvinhu zvearuminiyamu alloy.
