1. Ithusi iyingxubevange eyakhiwe ngethusi ne-zinc. I-Brass eyakhiwe ngethusi ne-zinc ibizwa ngokuthi ithusi elijwayelekile. Uma kuyizinhlobonhlobo zama-alloys ezakhiwe izakhi ezingaphezu kwezimbili, kubizwa ngokuthi ithusi elikhethekile. Ithusi linokumelana okuqinile nokugqokwa. I-Brass ivame ukusetshenziselwa ukwenza ama-valve, amapayipi amanzi, amapayipi axhumayo ama-air conditioners angaphakathi nangaphandle, nama-radiator.

2. Ithusi elibomvu, elaziwa nangokuthi ithusi elibomvu, liyinto nje yethusi, ebizwa kanjalo ngenxa yombala walo onsomi-obomvu. Bheka ithusi ngezakhiwo ezahlukahlukene. Ithusi elibomvu ithusi elimsulwa lemboni elinendawo yokuncibilika engu-1083°C, akukho ukuguqulwa kwe-allotropic, kanye nokuminyana okuhlobene okungu-8.9, okuphindwe kahlanu kune-magnesium. Isisindo somthamo ofanayo cishe sisinda ngo-15% kunensimbi evamile.

Ithusi elibomvu ngokuvamile libizwa ngokuthi ithusi elibomvu ngenxa yombala walo obomvu ophundu futhi onsomi ngemva kokwakhiwa kwefilimu ye-oxide phezulu. Ithusi eliqukethe inani elithile lomoya-mpilo, ngakho libizwa nangokuthi ithusi eliqukethe umoya-mpilo.

3. Ithusi elibomvu liyithusi elimsulwa, elaziwa nangokuthi ithusi elibomvu, eliyinto nje yethusi, futhi liqanjwe ngenxa yombala walo onsomi-obomvu. Bheka ithusi ngezakhiwo ezahlukahlukene. Ithusi elibomvu ithusi elimsulwa lemboni elinendawo yokuncibilika engu-1083°C, akukho ukuguqulwa kwe-allotropic, kanye nokuminyana okuhlobene okungu-8.9, okuphindwe kahlanu kune-magnesium.

Isisindo somthamo ofanayo cishe sisinda ngo-15% kunensimbi evamile. Ngenxa yokuthi inombala obomvu we-rose futhi inobunsomi ngemva kokwakhiwa kwefilimu ye-oxide phezulu, ngokuvamile ibizwa ngokuthi ithusi. Ithusi eliqukethe inani elithile lomoya-mpilo, ngakho libizwa nangokuthi ithusi eliqukethe umoya-mpilo.

Ithusi elibomvu line-conductivity kagesi enhle kanye ne-thermal conductivity, i-plasticity enhle kakhulu, futhi kulula ukucutshungulwa ngokucindezela okushisayo nokubandayo. Isetshenziswa kabanzi ekwenzeni izintambo zikagesi, izintambo, amabhulashi kagesi, nethusi elikhethekile le-electrolytic lezinhlansi zikagesi neminye imikhiqizo edinga ukuqhutshwa kahle kukagesi.

Umehluko phakathi kwethusi nethusi

1. Umbala wokubukeka

Ithusi: Iphuzi ngokusagolide futhi iyacwebezela.

Ithusi: Irozi libomvu, liyacwebezela.

2. Izithako

Ithusi elibomvu: Okuqukethwe kwethusi sekufinyelele ku-99.9%.

Ithusi: cishe u-60% wethusi; cishe 40% we-zinc; amanye amabanga aqukethe cishe u-1% womthofu, okuwukungcola.

3. Amandla

Ithusi: ngaphezulu.

Ithusi: ngaphansi.

4. Ukuminyana

Ukuminyana kwethusi (8.93g/cm3) kusetshenziswa kakhulu ulayini othwalayo, futhi ayigugi. Izinsimbi zethusi zivame ukusetshenziselwa ukwenza ama-valve nokufakwa kwamapayipi.

Ithusi elibomvu. Ikhopha ehlanzekile, eyaziwa nangokuthi ithusi elibomvu, inokuqina (7.83g/cm3), indawo yokuncibilika engu-1083 degrees, futhi ayinawo uzibuthe.

Ukusebenza okuyinhloko:

1. Inhlangano yezinga lokushisa kwegumbi

Ithusi elivamile liyi-alloy kanambambili yethusi ne-zinc, futhi okuqukethwe kwayo kwe-zinc kuyahlukahluka kakhulu, ngakho-ke isakhiwo sayo sokushisa kwekamelo sihluke kakhulu.

2. Ukusebenza kokucubungula ingcindezi

I-α yesigaba esisodwa sethusi (kusuka ku-H96 kuya ku-H65) inepulasitiki elihle futhi ingakwazi ukumelana nokushisa nokubandayo, kodwa i-α yesigaba esisodwa sethusi ijwayele ukushisa okuphakathi kwezinga lokushisa ngesikhathi sokusebenza okushisayo okufana ne-forging, futhi izinga lokushisa layo elithile liyahlukahluka ngokuqukethwe kwe-Zn. Ushintsho ngokuvamile luphakathi kuka-200 no-700°C.

3. Izakhiwo zemishini

Ngenxa yokuqukethwe kwe-zinc ehlukene yethusi, izakhiwo zemishini nazo zihlukile. Izici zemishini zethusi ziyahlukahluka ngokuqukethwe kwe-zinc. Nge-alpha brass, njengoba okuqukethwe kwe-zinc kwanda, kokubili u-σb kanye no-δ kuyaqhubeka nokukhula.

Umthombo oyisithenjwa: I-inthanethi
Umusho wokuzihlangula: Ulwazi oluqukethwe kulesi sihloko olokubhekisela kuphela, hhayi njengesiphakamiso esiqondile sokwenza izinqumo. Uma ungahlosile ukwephula amalungelo akho omthetho, sicela usithinte kusenesikhathi.
