Xa kuthelekiswa ukuqhutyelwa kombane kwe-aluminium kunye nobhedu, izinto ezininzi kufuneka ziqwalaselwe, kuquka iimpawu zabo zombane zangaphakathi, ubunzima, iindleko, kunye nezicelo eziqhelekileyo. Nalu uthelekiso oluneenkcukacha:

Ukuqhuba koMbane

• Ubhedu: Ubhedu lune conductivity yombane malunga ne-5.96 × 10⁷$\text{S/m}$ (siemens ngemitha nganye). Ngumgangatho apho abanye abaqhubi balinganiswa kwaye babelwa i-conductivity 100% Umgangatho weCopper we-Annealed International (IACS).
• Aluminiyam: I-Aluminiyam ine-conductivity yombane malunga ne-3.77 × 10⁷$\text{S/m}$, leyo malunga 63% leyo ye-IACS yobhedu.

Ubunzima kunye nobuninzi

• Ubhedu: I ukuxinana kobhedu imalunga ne 8.96 g/cm³. Oku kwenza ubhedu lubenzima xa luthelekiswa ne-aluminiyam.
• Aluminiyam: I Ubuninzi be-aluminiyam ijikeleze 2.7 g/cm³. I-aluminiyam ilula kakhulu, malunga nesinye kwisithathu ubunzima bobhedu.

Amandla kunye neePropati zoomatshini

• Ubhedu: I-Copper yomelele kwaye yomelele ngakumbi phantsi koxinzelelo lomatshini kwaye inokumelana nemithwalo ephezulu ngaphandle kokuguqulwa.
• Aluminiyam: I-aluminiyam ithambile ngakumbi kwaye ayithandeki ukophuka kodwa inamandla asezantsi okuqina xa kuthelekiswa nobhedu.

Iindleko

• Ubhedu: Ngokubanzi, ubhedu lubiza kakhulu ngenxa yemfuno ephezulu kunye neempawu eziphezulu zombane.
• Aluminiyam: I-aluminiyam ayibizi kakhulu kwaye ininzi kakhulu, iyenza ibe yenye indleko esebenzayo kwizicelo ezininzi.

Usetyenziso

• Ubhedu: Isetyenziswe kakhulu kwiintambo zombane, iinjini, iinguqu, kunye neenkqubo zokuvelisa amandla ngenxa yendlela egqwesileyo yokusebenza kunye nokuqina.
• Aluminiyam: Ngokuqhelekileyo isetyenziselwa ukuhanjiswa kwamandla kunye nemigca yokuhambisa, apho ubunzima bayo obulula bunokunciphisa kakhulu iindleko zenkxaso yesakhiwo.

Iingcamango Eziluncedo

• Ubungakanani kunye nobunzima boKusebenza ngokulinganayo: Ukufezekisa ukuhanjiswa kombane okufanayo njengobhedu, umqhubi we-aluminiyam kufuneka abe nommandla omkhulu we-cross-sectional. Nangona kunjalo, nokuba nobukhulu obukhulu, ubunzima obubonke babaqhubi be-aluminiyam busengaphantsi kunobo babaqhubi bobhedu.
• Ukunyangwa kokuMhlwa: I-Aluminiyam yenza umaleko okhuselweyo okhuselweyo owenza ukuba unganyangeki ekudlekeni. Ubhedu lunokugqwala, ngakumbi kwiindawo ezithile, kodwa oku kuhlala kulawulwa ngokutyabeka okufanelekileyo kunye nonyango.
• Ukuthembeka koQhagamshelwano: Aluminiyam ifuna ukuphathwa ngononophelo ukuqinisekisa uqhagamshelo olukhuselekileyo, njengoko inokwandisa kwaye inkontileka ngaphezu kobhedu kunye nokutshintsha kweqondo lokushisa, okunokukhokelela kunxibelelwano oluxengaxengayo ekuhambeni kwexesha. Izihlanganisi ezikhethekileyo kunye neendlela zokufakela zisetyenziselwa ukunciphisa oku.
