Ithusi
Ukusetshenziswa kwethusi nethusi kwaqala emakhulwini eminyaka adlule, futhi namuhla isetshenziswa kobunye ubuchwepheshe bamuva kanye nezinhlelo zokusebenza ngenkathi isasetshenziswa kuyizinhlelo zokusebenza zendabuko ezifana nezinsimbi zomculo, ama-eyelets ethusi, izindatshana zokuhlobisa kanye nehardware kampompi nomnyango.
I-Brass Yenziwe Ngani?
Ithusi ingxubevange eyenziwe ngethusi ne-zinc ukuze kukhiqizwe izinto ezinohlu olubanzi lokusetshenziswa kobunjiniyela. Ukubunjwa kwethusi kunikeza insimbi indawo yokuncibilika efanelekile ezinhlelweni eziningi, okuhlanganisa nokufanelekela ukujoyina kusetshenziswa indlela yokubhula. Iphuzu lokuncibilika lethusi liphansi kunekhopha cishe ku-920 ~ 970 degrees Celsius kuye ngenani lokwengezwa kwe-Zn. Iphuzu lokuncibilika kwethusi liphansi kunelethusi ngenxa ye-Zn eyengeziwe. Ama-alloys ethusi angahluka ekubunjweni kwe-Zn kusukela kokuncane okufika ku-5% (okuvame ukubizwa ngokuthi izinsimbi ze-Gilding) kuya ngaphezu kuka-40% njengoba kusetshenziswa kuma-machining brasses. Igama elingajwayelekile elisetshenziswa yithusi lethusi, lapho kusetshenziswa khona izithasiselo ezithile zamathini.
Ithusi lisetshenziselwa ini?
Ukwakheka kwethusi kanye nokwengezwa kwe-zinc ethusi kuphakamisa amandla futhi kunikeza uhla lwezici, okwenza amathusi abe uhla lwezinto ezihlukahlukene kakhulu. Zisetshenziselwa amandla azo, ukumelana nokugqwala, ukubukeka nombala, kanye nokusebenza kalula nokujoyina. I-alpha brasses yesigaba esisodwa, equkethe cishe u-37% Zn, i-ductile kakhulu futhi kulula ukusebenza ngokubandayo, i-weld kanye ne-braze. Izigaba ezimbili ze-alpha-beta brasses ngokuvamile ziyashisa.
Ingabe kukhona ukwakheka kwethusi okungaphezu kokukodwa?
Kunamathusi amaningi anezinhlobo ezahlukene nezici ezenzelwe izinhlelo zokusebenza ezithile ngezinga lokwengezwa kwe-zinc. Amazinga aphansi okwengezwa kwe-Zn avame ukubizwa nge-Guilding Metal noma i-Red Brass. Ngenkathi amazinga aphezulu e-Zn angama-alloys afana ne-Cartridge Brass, i-Free Machining Brass, i-Naval Brass. Lezi zethusi zakamuva nazo zinokungezwa kwezinye izakhi. Ukwengezwa komthofu wethusi sekusetshenziswe iminyaka eminingi ukusiza ubuciko bezinto ngokufaka amaphuzu okuphuka kwe-chip. Njengoba ubungozi kanye nobungozi bomthofu kuye kwaqashelwa ukuthi muva nje kushintshwe izakhi ezifana ne-silicon ne-bismuth ukuze kuzuzwe isici somshini esifanayo. Lokhu manje sekwaziwa njengokuhola okuphansi noma izithusi zamahhala eziholayo.
Ingabe ezinye izakhi zingengezwa?
Yebo, amanani amancane wezinye izakhi ze-alloying angase afakwe ethusi nasethusini. Izibonelo ze-Commons ziwumthofu wekhono lomshini njengoba kushiwo ngenhla, kodwa futhi i-arsenic yokumelana nokugqwala ukuze i-dezincification, ithini lamandla nokugqwala.
Umbala Wethusi
Njengoba okuqukethwe kwe-zinc kwanda, umbala uyashintsha. Ama-alloys e-Zn aphansi ngokuvamile angafana nethusi ngombala, kuyilapho ama-alloys e-zinc aphezulu abonakala esagolide noma aphuzi.

I-Gilding Metal
I-C22000, 90/10 Gilding metal, ihlanganisa umbala osagolide ocebile kanye nenhlanganisela engcono kakhulu yamandla, i-ductility kanye nokumelana nokugqwala kwama-alloys angenalutho e-Cu-Zn. Ishintsha isimo sezulu ibe nemibala yethusi ecebile. Inekhono elihle kakhulu lokudweba elijulile, kanye nokumelana nokugqwala kwemigodi esimweni sezulu esibi namanzi. Isetshenziswa ku-architectural fascias, ubucwebe, i-ornamental trim, izibambo zeminyango, ama-escutcheons, i-hardware yasolwandle.
Amathusi aphuzi
I-C26000, 70/30 Brass ne-C26130, i-Arsenical brass, ine-ductility namandla amahle kakhulu, futhi yizithusi ezisetshenziswa kakhulu. Ithusi le-arsenical liqukethe ukungezwa okuncane kwe-arsenic, okuthuthukisa kakhulu ukumelana nokugqwala emanzini, kodwa kufana ngokuphumelelayo. Lawa ma-alloys anombala ophuzi ogqamile ohlukile ovame ukuhlotshaniswa nethusi. Zinenhlanganisela enkulu yamandla kanye ne-ductility kuma-alloys e-Cu-Zn, kuhlanganiswe nokungagqwala okuhle. I-C26000 isetshenziselwa ukwakha, iziqukathi ezidwetshiwe neziphothiweyo, amatheminali kagesi nezixhumi, izibambo zezicabha, kanye nehardware ye-plumbers. I-C26130 isetshenziselwa ishubhu nokufakwa kuthintana namanzi, okuhlanganisa namanzi aphuzwayo.
I-C26800, Ithusi Eliphuzi, isigaba esisodwa se-alpha brass esinokuqukethwe okuphansi kwethusi. Isetshenziswa lapho izakhiwo zayo ezijulile zokudweba kanye nezindleko eziphansi zinikeza inzuzo. Lapho izinhlayiya ezishiselwe zesigaba se-beta zingase zakheke, kunciphise i-ductility kanye nokumelana nokugqwala.
Izinsimbi nezinye izakhi
I-C35600 ne-C37000, i-Engraving brass, zingamabhusi e-alpha-beta angama-60/40 anamazinga ahlukene omthofu angeziwe ukuze anikeze izici zamahhala zokwenza imishini. Zisetshenziswa kabanzi kumapuleti aqoshiwe nama-plaque, i-hardware yabakhi, amagiya. Akumele zisetshenziselwe umsebenzi ofakwe i-asidi, okumele kusetshenziswe ithusi lesigaba esisodwa se-alpha.
I-C38000, i-Section brass, iyithusi eliholayo le-alpha/beta eliphuma kalula elinesengezo esincane se-aluminium, esinikeza umbala osagolide ogqamile. Umthofu unikeza izici zokusika mahhala. I-C38000 itholakala njengezinduku, amashaneli, amaflethi nama-engeli, ngokuvamile asetshenziswa kuma-hardware abakhi.
I-C38500, ithusi lokusika, iyindlela ethuthukisiwe kakhulu ye-60/40 yethusi, enezici ezinhle kakhulu zokusika mahhala. Isetshenziswa ekukhiqizeni ngobuningi bezingxenye zethusi lapho okuphumayo okuphezulu nokuphila kwamathuluzi okude kakhulu kuyadingeka, futhi lapho kungadingeki khona ukwakheka okubandayo ngemva komshini.
