Mhangura ine mhangura isingaite ngura munzvimbo dzakaoma, asi inowanzoita patina munzvimbo yakakwirira-yakanyorova kana sarufa{{1}iine gasi, zvichiita kuti isarambe iine gasi. Iyo yepamusoro yealuminum inogadzirira kuumba dense oxide firimu, iyo inogona panzvimbo payo kudzivirira imwe corrosion. Zvisinei, kushorwa kwefirimu reoxide (inenge 10⁻⁶Ω·cm²) kwakakwirira kudarika yemhangura substrate (10⁻⁶Ω·cm²), uye inoda kuvandudzwa kuburikidza ne tin plating, nickel plating kana anodic oxidation kurapwa.
Mukutaura kwesimba rekushisa pamagetsi ekugadzirisa magetsi, chiyero chekushisa chekudzivirira kwemhangura (0.0043 / dhigirii) yakaderera pane iyo yealuminium (0.0041 / degree), asi iyo coefficient yekuwedzera kwekushisa kwealuminium (23.6 × 10⁻⁶/ degree) ndeye 1.4 nguva iyo yemhangura . Mumamiriro ezvinhu ane kushanduka kwekushisa kwakanyanya, kuwedzera kwekupisa uye kudonhedzwa kwemaaruminiyamu mabara kunowedzera kutaurwa, izvo zvinogona kukonzera kusunungura panzvimbo dzekubatanidza. Izvi zvinogona kudzikiswa kuburikidza nedhizaini yezvimiro (sekuchengetedza mapeji ekuwedzera) kana nekushandisa zvinobatika zvinobatanidza.
