Brass ine zinc nekuti chinhu chikuru chealloy yemhangura, ine yero yakanaka, pamwe chete yakati sendarira. Copper zinc binary alloy inonzi yakajairika ndarira kana nyore ndarira. Brass ine mayuan matatu chaiwo inonzi yakakosha bras kana yakaoma brass. Brass alloys ine asi 36% zinc inoumbwa nemhinduro dzakasimba uye ine yakanaka kutonhora kushanda kushanda. semuenzaniso, ndarira ine 30% zinc inowanzojairwa kugadzira ganda casings, inowanzonzi shell brass kana makumi manomwe nenhatu ndarira. Brass alloys ine zinc zviri pakati pe36 ne42% inoumbwa uye yakasimba mhinduro, iyo inonyanya kushandiswa ibrass ine hexagonal ine zinc ye40%. kuitira kuti ukwidziridze kushanda kwendarira yakajairwa, zvimwe zvinhu zvinowanzowedzerwa, sealuminium, nickel, manganese, tin, silicon, lead uye zvichingodaro. Aluminium inogona kuvandudza kusimba, kuoma uye kushorwa kwendarira, asi kuderedza purasitiki, saka yakakodzera Marine condensing tubes uye zvimwe zvinodzivirira corrosion parts. Tin inogona kuvandudza kusimba kwendarira uye kusaita ngura kumvura yegungwa, saka inodaidzwa kunzi Tobin bronze, inoshandiswa kugadzira midziyo yekudziya yengarava uye mapropeller. Mutungamiri unogona kuvandudza kushanda kwekucheka kwendarira. Iyi yemahara yekucheka ndarira inowanzoshandiswa sechikamu chewachi. Brass castings inowanzojairika kuita mavharuvhu uye pombi fittings.
Bronze pakutanga inoreva mhangura-tin alloy, gare gare maalloys emhangura kunze kwendarira nechena mhangura yose inonzi bhuronzi, uye bhuronzi inowanzotangirwa nezita rechinhu chikuru chakawedzerwa chinhu. Tin bhuronzi ine yakanaka yekukanda kuita, friction yekudzikisa kuita uye michina zvivakwa, yakakodzera kugadzira mabearings, giya vhiri uye ipapo. Bronze yemutobvu inogona kunge iri chinhu chinotakura chinoshandiswa zvakanyanya mumainjini emazuva ano nemichina yekukuya. mhangura-base alloy ine simba rakawanda, yakanaka kupfeka kuramba uye kusagadzikana kwekuora. inoshandiswa kukanda magiya, bushings uye Marine propellers ane mutoro wakakwira. bronze uye phosphatic bhuronzi ine yakakwira elastic miganhu uye yakanaka magetsi conductivity, zvichiita kuti ive yakakodzera kugadzirwa kweiyo chaiyo zvitubu uye tangency zvinhu. bhuronzi inoshandiswawo mukugadzira maturusi asingapeniri anoshandiswa mumigodhi yemarasha uye nezvinotapudza oiri.
A alloy yemhangura ine nickel nekuti main additive element. Cu-ni binary alloy inonzi yakajairika mhangura chena; Wedzera manganese, simbi, zingi, aruminiyamu uye zvimwe zvinhu zvewhite copper alloy inonzi yakaoma mhangura. Industrial chena mhangura yakakamurwa kuita chena mhangura uye yemagetsi chena mhangura mapoka maviri. Chimiro chemhangura chena chinoratidzwa nemaitiro akanaka emagetsi uye kusagadzikana kwekuora, ruvara rwakanaka. Iyo chena mhangura inoshandiswa zvakanyanya mumichina chaiyo, makemikari muchina uye Marine zvikamu.
Mhangura inowana zita rayo kubva muruvara rutsvuku. haisati iri mhangura yakachena, uye dzimwe nguva hushoma hwezvinhu zve deoxidation kana zvimwe zvinhu zvinowedzerwa kuwedzera jira nekuita, saka inoiswawo semhangura alloy. zvinoenderana nekuumbwa kweChinese copper processing materials inowanzo patsanurwa muzvikamu zvina: yakajairika mhangura, oxygen-isina mhangura, deoxidized copper, yakakosha mhangura ine shoma shoma yezvinhu zvinosanganiswa. Mhangura ndeyechipiri kune sirivheri mune conductivity uye thermal conductivity, uye inoshandiswa zvakanyanya mukusangana kwemagetsi uye ekupisa conductive midziyo. Mhangura mukati memhepo, mvura yegungwa uye mashoma asiri oxidizing acids, alkali, munyu mhinduro uye kupararira kwe organic acids (acetic acid, citric acid), ine yakanaka corrosion resistance, inoshandiswa muindasitiri. Pamusoro pezvo, mhangura tsvuku ine weldability yakanaka, inogadzirwa mumhando yezvigadzirwa zvehafu-yapera uye zvigadzirwa zvakapedzwa nekutonhora uye thermoplastic processing.
