2. Iimpawu
Iimpawu ezichanekileyo zeebrass ezahlukeneyo zixhomekeke kulwakhiwo lwe-alloy yobhedu, ingakumbi umlinganiselo we-copper-zinc. Nangona kunjalo, ngokubanzi, zonke iibrass zixatyiswa ngenxa yobuchule bazo bokusebenza okanye ukulula kwendlela isinyithi esinokwenziwa ngayo sibe yimilo kunye neefom ezifunwayo ngelixa sigcina amandla aphezulu.

Nangona kukho umahluko phakathi kweebrasses ezinomxholo we-zinc ophezulu nophantsi, zonke iibrasses zithathwa njengezinokunyibilika kwaye zithambile (iibrasses ze-zinc eziphantsi kakhulu). Ngenxa yokuba zinyibilika kancinci, ibrass inokuphoswa ngokulula. Nangona kunjalo, kwizicelo zokuphoswa, umxholo we-zinc ophezulu uhlala ukhethwa.

Iibrass ezinomthamo omncinci we-zinc zinokucocwa lula, zifakwe i-weld kwaye zifakwe i-brass. Umthamo ophezulu we-copper ukwavumela isinyithi ukuba senze umaleko we-oxide okhuselayo (patina) kumphezulu waso okhusela ukubola okungakumbi, into exabisekileyo xa isetyenziswa ebeka isinyithi kumswakama kunye nokuguquguquka kwemozulu.

Isinyithi sinobushushu obuhle kunye nombane (umbane waso ungafikelela kwi-23% ukuya kwi-44% kunowethusi olucocekileyo), kwaye asigugi kwaye asitshisi. Njengethusi, iimpawu zaso zebhaktiriya zibangele ukusetyenziswa kwaso kwiindawo zokuhlambela nakwizibonelelo zonyango.

I-brass ithathwa njenge-alloy engaphantsi kokungqubana kunye ne-non-magnetic, ngelixa iimpawu zayo ze-acoustic zibangele ukusetyenziswa kwayo kwizixhobo zomculo ezininzi 'zebhendi yebrass'. Iingcibi kunye nabayili bezakhiwo bayayixabisa impawu zobuhle besinyithi, njengoko sinokuveliswa ngemibala eyahlukeneyo, ukusuka kubomvu obunzulu ukuya kumthubi wegolide.

3. Izicelo
Iimpawu ezixabisekileyo zeBrass kunye nokulula kokuveliswa kwayo kwenze ukuba ibe yenye yezona alloys zisetyenziswa kakhulu. Ukuqokelela uluhlu olupheleleyo lwazo zonke izicelo zebrass kungaba ngumsebenzi omkhulu, kodwa ukuze ufumane umbono wamashishini kunye neentlobo zeemveliso apho ibrass ifumaneka khona singahlulahlula size sishwankathele ezinye zeendlela zokusetyenziswa ngokusekelwe kudidi lwebrass esetyenzisiweyo:
● Ithusi lokusika elikhululekileyo (umz. C38500 okanye 60/40 ithusi):
● Amantongomane, iibholiti, iindawo ezinemisonto
● Iitheminali
● IiJethi
● Iimpompo
● Ii-injectors

4. Imbali
Ii-alloy zeCopper-zinc zaveliswa kwangenkulungwane yesi-5 BC eTshayina kwaye zazisetyenziswa kakhulu kumbindi weAsia ngenkulungwane yesi-2 neyesi-3 BC. Nangona kunjalo, ezi ziqwenga zesinyithi zokuhombisa zinokubizwa ngokuba 'zii-alloy zendalo,' njengoko kungekho bungqina bokuba abavelisi bazo bazenze ngabom i-copper kunye ne-zinc. Endaweni yoko, kusenokwenzeka ukuba ezi alloy zazinyibilikiswa kwiintsimbi zekopolo ezityebileyo zi-zinc, zivelisa iintsimbi ezifana ne-brass.

Iingxelo zamaGrike namaRoma zibonisa ukuba ukuveliswa ngabom kwee-alloys ezifana nobhedu lwanamhlanje, kusetyenziswa i-copper kunye ne-zinc oxide-rich ore eyaziwa ngokuba yi-calamine, kwenzeka malunga nenkulungwane yoku-1 BC. I-calamine brass yenziwa kusetyenziswa inkqubo ye-cementation, apho i-copper yayinyibilikiswa kwi-crucible nge-ground smithsonite (okanye i-calamine) ore.

Kwiqondo lobushushu eliphezulu, i-zinc ekhoyo kwi-ore enjalo ijika ibe ngumphunga ize ingene kwi-copper, ngaloo ndlela ivelise i-copper ecocekileyo enomxholo we-zinc oyi-17-30%. Le ndlela yokuvelisa i-copper yasetyenziswa phantse iminyaka engama-2000 ukuya ekuqaleni kwenkulungwane ye-19. Kungekudala emva kokuba amaRoma efumanise indlela yokuvelisa i-copper, le ngxube yayisetyenziselwa ukwenza iingqekembe kwiindawo zaseTurkey yanamhlanje. Oku kwasasazeka ngokukhawuleza kulo lonke uBukhosi baseRoma.

5. Iintlobo
'I-Brass' ligama eliqhelekileyo elibhekisa kuluhlu olubanzi lwee-alloy ze-copper-zinc. Enyanisweni, kukho iintlobo ezahlukeneyo ze-bronze ezingaphezu kwama-60 ezichazwe yi-EN (European Norm) Standards. Ezi alloy zinokuba noluhlu olubanzi lwee-compositions ezahlukeneyo kuxhomekeke kwiimpawu ezifunekayo kwisicelo esithile.

6. Imveliso
I-brass idla ngokuveliswa ngee-copper slap kunye nee-zinc ingots. I-scrap copper ikhethwa ngokusekelwe kukungcola kwayo, njengoko kufuneka ezinye izinto ezongezelelweyo ukuze kuveliswe uhlobo oluchanekileyo lwe-bross olufunekayo.
Ngenxa yokuba i-zinc iqala ukubila ize iphele ngomphunga kwi-1665°F (907°C), ngaphantsi kweqondo lokunyibilika kobhedu kwi-1981°F (1083°C), ubhedu kufuneka luqale lunyibilike. Nje ukuba lunyibilike, i-zinc yongezwa kwisilinganiso esifanelekileyo somgangatho wobhedu oluveliswayo. Nangona kusafuneka ukuba kubekho isibonelelo sokulahleka kwe-zinc xa iphuma.

Kule ndawo, naziphi na ezinye iintsimbi ezongezelelweyo, ezifana ne-lead, i-aluminium, i-silicon okanye i-arsenic, zongezwa kumxube ukwenza i-alloy efunekayo. Nje ukuba i-alloy enyibilikisiweyo ilungile, igalelwa kwiimolds apho iqina khona ibe zii-slabs ezinkulu okanye ii-billets. Ii-Billets - ezidla ngokuba zeze-alpha-beta brass - zinokucutshungulwa ngokuthe ngqo zibe ziintambo, iipayipi, kunye neetyhubhu nge-extrusion eshushu, equka ukutyhala isinyithi esishushu nge-die, okanye i-hot forging.

Ukuba azikhutshelwanga okanye azikho zixhobo, ii-billets ziyafudunyezwa kwakhona kwaye zondliwe ngee-roller zentsimbi (inkqubo eyaziwa ngokuba yi-hot rolling). Isiphumo yi-slabs ezinobukhulu obungaphantsi kwesiqingatha se-intshi (<13mm). Emva kokupholisa, i-brass emva koko yondliwe ngomatshini wokusila, okanye i-scalper, esika umaleko omncinci kwisinyithi ukuze kususwe iziphene zokubumba umphezulu kunye ne-oxide.

Phantsi kwemoya oshushu ukuze kuthintelwe i-oxidization, i-alloy iyafudunyezwa ize iqengqelwe kwakhona, inkqubo eyaziwa ngokuba yi-annealing ngaphambi kokuba iphinde iqengqelwe kwakhona kumaqondo obushushu apholileyo (i-cold rolling) ukuya kumashiti anobukhulu obuyi-0.1" (2.5mm). Inkqubo yokuqengqelwa ebandayo iguqula isakhiwo sangaphakathi se-brass, nto leyo ebangela isinyithi esomeleleyo nesiqinileyo. Eli nyathelo linokuphindwa de kufikelelwe kubukhulu okanye ubunzima obufunekayo.

Okokugqibela, amaphepha ayasahwa aze achetywe ukuze kuveliswe ububanzi nobude obufunekayo. Onke amaphepha, izinto ezenziwe ngobhedu, ezenziwe ngobumba, kunye nezinto ezenziwe ngobhedu ezikhutshiweyo zinikwa ukuhlamba ngamakhemikhali, ngokuqhelekileyo, okwenziwe nge-hydrochloric kunye ne-sulfuric acid, ukususa isikali se-black copper oxide kunye nokubola.

IJindalai igcina amaphepha ethusi kunye neekhoyili ngobukhulu obuqala kwi-0.05 ukuya kwi-50mm, kwaye kwi-annealed, quarter hard, half hard, kunye ne-full hard tempers. Ezinye ii-tempers kunye nee-alloys ziyafumaneka. Thumela umbuzo wakho kwaye siya kukuvuyela ukubonisana nawe ngobuchwephesha.
