Yikuphi okubonakalayo okungcono kakhulu kwesithwebuli somunwe?

Izinto zokuthwebula zeminwe emakethe zihlukaniswe ngensimbi engenacala, ithusi, i-zinc alloy, insimbi ne-aluminium.

Insimbi inamandla amahle nezindleko eziphansi, kepha kulula ukugqwala. Isetshenziswa ngokuvamile njengento yangaphakathi yokumaka okukhiyiwe futhi ayilungele umhlobiso wangaphandle.
I-Aluminium noma i-Aluminium Alloy, i-aluminium evamile i-alloy ithambile futhi ilula, inamandla aphansi ngokwezinto, kepha kulula ukucubungula nokwakha.
Insimbi engenasici ihamba phambili njengezinto eziqinile, ikakhulukazi njengento engaphezulu. Lapho isetshenziswa kakhulu, kuba nzima. Inamandla amahle, ukumelana okuqinile kokugqwala nombala ongashintshiwe. Kepha kunezinhlobo eziningi zensimbi engenasici, ezingahlukaniswa ikakhulu zaba nguFerrite ne-Auden. Insimbi engenasici ka-Ferritic ingubuthe futhi isaziwa kakhulu njengensimbi engenacala. Izogqwala ngokuhamba kwesikhathi nasendaweni embi. Insimbi engagqwali futhi iyona engcono kakhulu yensimbi engasebenzi phakathi kwamanye ama-steres angenasici.
Izinto zokwenziwa ze-Zinc Alloy zinobunzima obukhulu kakhulu kanye nekhono lokulwa nokugqwala. Ngisho ne-electroplating obukhulu bathambekele ekuqothulweni, ukuguqula okumnyama, ukubola nokukhala. Kodwa-ke, inzuzo yayo ukuthi kulula ukwenza izingxenye ngamaphethini ayinkimbinkimbi, ikakhulukazi ukucindezela kwengcindezi. Izikhiye ezinamaphethini abumbana amaningi abonwa emakethe kungenzeka zenziwe nge-zinc alloy, ngakho-ke abathengi kufanele bakhombe ngokucophelela.
I-Copper ingenye yezinto ezisetshenziswa kakhulu zokukhiya. Inezakhiwo ezinhle zemishini, ukumelana kahle nokugqwala nokusebenza, futhi kukhanya ngombala. Izibambo ezakhiwe nge-zethusi ikakhulukazi nezinye izingxenye zokuhlobisa zokuhlobisa zinobumbano obushelelezi, ukuqina okuhle, futhi akukho pores. I-Trachoma. Amathuluzi e-Pneumatic anamandla futhi aburruc-proof, futhi angasetshenziselwa ukwelashwa okuhlukahlukene okufana nokufakwa kwegolide kwegolide noma indawo yegolide yegolide. Babukeka kahle kakhulu, muhle futhi uphane, bese wengeza umbala omningi emizini yabantu.
