Iipropati zezinto ezingundoqo
Ukusebenza okugqwesileyo kwei-aluminium ecocekileyo kakhulu ivela kwiezine ezichaza iimpawu zomzimba.
Okokuqala, ukuhanjiswa kwayo kombane kufikelela kumda wethiyori. Ukulandela umthetho kaMatthiessen, ii-athomu zokungcola ziphazamisa i-lattice yekristale ye-aluminiyam kwaye zenze amaziko okusasaza i-electron athintela ukuhamba kombane. Ubunyulu obuphezulu buthetha isakhiwo sekristale esigqibeleleyo, nto leyo ebangela ukuhanjiswa kombane okuphezulu. I-aluminium ye-4N grade inokufikelela kwi-98% yokuhanjiswa kwethiyori ye-aluminium ecocekileyo, inika ubushushu obuphantsi bokumelana nokusebenza kakuhle kwamandla.
Okwesibini, inika ukuhanjiswa kobushushu okugqwesileyo. I-aluminium ecocekileyo kakhulu ifikelela ekuhanjisweni kobushushu obuyi-235 ~ 240 W/(m·K), kufutshane nomlinganiselo ophezulu wethiyori.
