Mhangura, Brass uye Bronze, neimwewo inozivikanwa se "Red Metals", inogona kutaridzika zvakafanana pakutanga asi yakanyatso siyana.
Mhangura
Mhangura inoshandiswa mumhando dzakasiyana-siyana dzezvigadzirwa nekuda kwekunaka kwayo kwemagetsi uye kupisa kwemhepo, simba rakanaka, kuumbwa kwakanaka uye kushorwa kwekuora. Pombi uye pombi fittings anowanzo gadzirwa kubva masimbi aya nekuda kwekupokana kwawo. Dzinogona kutengeswa nyore nyore uye dzakashongedzwa, uye dzakawanda dzinogona kugadzirwa neakasiyana gasi, arc uye nzira dzekupikisa. Ivo vanogona kukwenenzverwa uye kubhurwa kunenge chero inodiwa magadzirirwo uye kupenya.
Kune mamakisi eCopper isina kurongeka, uye anogona kusiyana muhuwandu hwetsvina irimo. Oxygen-isina mhangura mamakisi anoshandiswa zvakananga mumabasa uko yakakwirira conductivity uye ductility inodiwa.
Chimwe chezvinhu zvakakosha zvemhangura ndiko kukwanisa kurwisa mabhakitiriya. Mushure mekuongororwa kwakawanda kweantimicrobial neEnvironmental Protection Agency, zvakaonekwa kuti 355 copper alloys, kusanganisira mabhurashi akawanda, akawanikwa achiuraya zvinopfuura 99.9% zvebhakitiriya mukati maawa maviri ekubatana. Kusvibiswa kwakajairwa kwakawanikwa kusakanganisa kushanda kweantimicrobial.
Mhangura Applications
Mhangura ndiyo imwe yesimbi dzakatanga kuwanikwa. VaGiriki nevaRoma vakaigadzira kuva maturusi kana zvishongo, uye kune kunyange nhoroondo dzezvakaitika kare dzinoratidza kushandiswa kwemhangura kuchenesa maronda uye kuchenesa mvura yekunwa. Nhasi inonyanya kuwanikwa mumidziyo yemagetsi senge wiring nekuda kwekugona kwayo kuita magetsi zvakanaka.
Brass
Brass inonyanya kuve alloy ine mhangura ine zinc yakawedzerwa. Mabhureshi anogona kuve neakasiyana siyana ezinc kana zvimwe zvinhu zvakawedzerwa. Iyi misanganiswa yakasiyana-siyana inobudisa zvakasiyana-siyana zvezvivakwa uye kusiyana kwemavara. Yakawedzera huwandu hwezinc inopa izvo zvinhu zvine simba rakagadziridzwa uye ductility. Brass inogona kubva muruvara kubva kutsvuku kusvika kune yero zvichienderana nehuwandu hwezinc yakawedzerwa kune alloy.
- Kana iyo zinc yemukati yendarira ichibva pa32% kusvika 39%, ichave yakawedzera kupisa-kushanda kugona asi kutonhora-kushanda kuchave kushoma.
- Kana iyo ndarira ine inopfuura 39% zinc (muenzaniso - Muntz Metal), ichava nesimba rakakwirira uye yakaderera ductility (pakamuri tembiricha).
Brass Applications
Brass inowanzoshandiswa pakushongedza chinangwa kunyanya nekuda kwekufanana kwayo negoridhe. Iri zvakare rinowanzoshandiswa kugadzira zviridzwa zvemimhanzi nekuda kwekunyanya kushanda kwayo uye kusimba.
Dzimwe Brass Alloys
Tin Brass
Iyi alloy ine mhangura, zingi uye tin. Iri boka re alloy raizosanganisira admiralty brass, naval brass uye yemahara machining brass. Iyo tini yakawedzerwa kuti inhibit dezincification (iyo leaching ye zinc kubva kumhangura alloys) munzvimbo dzakawanda. Iri boka rine kushomeka kwekunzwa kune dezincification, simba riri pakati nepakati, yakakwirira mumhepo uye aqueous corrosion resistance uye yakanakisa magetsi conductivity. Ivo vane hunhu hwakanaka hwekupisa uye kutonhora kwakanaka kuumbwa. Aya ma alloys anowanzo shandiswa kugadzira ma fasteners, marine Hardware, screw machine parts, pombi shafts uye corrosion-resistant mechanical products.
Bronze
Bronze is a alloy iyo inosanganisira kunyanya yemhangura pamwe nekuwedzerwa kwezvimwe zvinhu. Kazhinji kacho chinongedzo chinowedzerwa chinowanzoita tin, asi arsenic, phosphorus, aruminiyamu, manganese, uye silicon inogonawo kushandiswa kugadzira zvinhu zvakasiyana muzvinyorwa. Zvose izvi zvinoshandiswa zvinogadzira alloy yakaoma zvikuru kupfuura mhangura chete.
Bronze inoratidzwa neyakasvibira-goridhe ruvara. Iwe unogona zvakare kuziva mutsauko pakati pendarira nendarira nekuti ndarira ichange iine zvindori zvisina simba pamusoro payo.
Bronze Applications
Bronze inoshandiswa mukuvaka zvivezwa, zviridzwa zvemimhanzi uye menduru, uye mumaindasitiri ekushandisa senge bushings uye mabearings, uko yakaderera simbi pane simbi friction inobatsira. Bronze zvakare ine nautical application nekuda kwekupokana kwayo nekuora.
Mamwe maBronze Alloys
Phosphor Bronze (kana Tin Bronze)
Iyi alloy kazhinji ine tin yemukati inotangira pa 0.5% kusvika 1.0%, uye phosphorous range ye 0.01% kusvika 0.35%. Aya ma alloys akakosha pakusimba kwawo, simba, kuderera kweyekukoirana, kukwirira kuneta kuramba, uye zviyo zvakanaka. Iyo tin yemukati inowedzera corrosion kuramba uye kusimba simba, nepo phosphorus yemukati inowedzera kupfeka kuramba uye kuoma. Mamwe mashandisirwo ekupedzisira echigadzirwa ichi angave zvigadzirwa zvemagetsi, mabhero, zvitubu, washers, corrosion resistance equipment.
Aluminium Bronze
Izvi zvine aluminium content range ye6% -12%, iron content 6% (max), uye nickel content 6% (max). Izvi zvakasanganiswa zvinowedzera zvinopa simba rakawedzerwa, rakasanganiswa nekupokana kwakanaka kwekuora uye kupfeka. Nyaya iyi inowanzoshandiswa mukugadzira marine hardware, sleeve bearings nemapombi kana mavharuvhu anobata zvinwiwa zvinoparadza.
Silicon Bronze
Iyi alloy inogona kuvhara zvese zvendarira nebronze (tsvuku silicon brasses uye red silicon bronzes). Iwo anowanzo ane 20% zinc uye 6% silicon. Ndara tsvuku ine simba rakawanda uye corrosion resistance uye inowanzoshandiswa kune mavharuvhu madzinde. Bhuronzi tsvuku yakafanana chaizvo asi ine yakaderera yezinc. Inowanzoshandiswa mukugadzira pombi uye zvikamu zvevhavha.
Nickel Brass (kana Nickel Silver)
Iyi alloy ine mhangura, nickel uye zinc. Iyo nickel inopa zvinhu kuita senge sirivheri. Ichi chinyorwa chine simba riri pakati nepakati uye zvakaringana kunaka kwekuramba kwecorrosion. Ichi chinyorwa chinowanzo shandiswa kugadzira zviridzwa, chikafu uye chinwiwa midziyo, optical michina, uye zvimwe zvinhu uko aesthetics chinhu chakakosha.
Copper Nickel (kana Cupronickel)
Iyi alloy inogona kuva chero kubva 2% kusvika 30% nickel. Nyaya iyi ine yakanyanya corrosion-resistance uye ine thermal kugadzikana. Ichi chinyorwa chinoratidzawo kushivirira kwakanyanya kune corrosion kupaza pasi pekushushikana uye oxidation mumhepo inopfungaira kana yakanyorova. Yepamusoro nickel yemukati mune ino chinyorwa ichave yakavandudza kusadzivirirwa kwekuora mumvura yegungwa, uye kuramba kusvibiswa kwezvipenyu zvegungwa. Ichi chinyorwa chinowanzo shandiswa mukugadzira zvigadzirwa zvemagetsi, midziyo yemugungwa, mavharuvhu, pombi uye zvikepe zvengarava.
