Isethulo somkhiqizo:
Ithusi elihlanzekile liyithusi elinenani eliphakeme kakhulu lethusi, ngoba ingxenye eyinhloko yethusi kanye nesiliva, okuqukethwe yi-99.5 ~ 99.95%;izakhi eziyinhloko zokungcola: i-phosphorus, i-bismuth, i-antimony, i-arsenic, insimbi, i-nickel, i-lead, insimbi, ithini, isulfure, i-zinc, umoya-mpilo, njll.;esetshenziswa ukwenza imishini conductive, ingxubevange yethusi advanced, ingxubevange yethusi-based.
I-aluminium yethusi ingahlukaniswa izigaba ezimbili.Enye iphonsa i-aluminium yethusi ukuze isuse ukungcola futhi ikhulise uketshezi, ingxubevange ingeqi ku-0.5%;enye ihlanganisa i-aluminium yethusi ukuze kwandiswe ukumelana nokugqwala, evame ukusetshenziswa njengepayipi elijiya, ububanzi bokwakheka okujwayelekile ngu-Al1~6%, Zn 24 ~ 42%, kanye ne-Cu 55 ~ 71%.
