Machubhu eCuZn36 eBrass / Copper

CuZn36, chiumbwa chemhangura-zinc, chinozivikanwa sebrass. CuZn36 brass imhando ine 64% copper uye 36% zinc. Chiumbwa ichi chine dhaka shoma mumhuri yebrass asi chine zinc yakawanda, saka chine zvimwe zvinhu zvepanyama uye zvemakanika zvakakodzera kushandiswa mumaindasitiri akasiyana-siyana. Nekuda kwehunhu hwayo hwakanaka hwemakanika uye hunhu hwekugadzirisa, CuZn36 inoshandiswa zvakanyanya mukugadzira zvikamu zvakasiyana-siyana zvemakanika, zvisungo, masprings, nezvimwewo.

Kuumbwa kwemakemikari

Kuumbwa kwemakemikari eCuZn36 ndekwekuti:

· Mhangura (Cu): 63.5-65.5%

· Simbi (Fe): ≤0.05%

· Nickel (Ni): ≤0.3%

· Mutobvu (Pb): ≤0.05%

· Aruminiyamu (Al): ≤0.02%

· Tin (Sn): ≤0.1%

· Zvimwe zvese: ≤0.1%

· Zinc (Zn): Kuenzana

Zvimiro zvemuviri

Hunhu hweCuZn36 hunosanganisira:

· Kuwanda: 8.4 g/cm³

· Nzvimbo yekunyunguduka: inenge 920°C

· Kugona kupisa kwakanangana: 0.377 kJ/kgK

· Modulus yaYoung: 110 GPa

· Kufambisa kwekupisa: inenge 116 W/mK

· Kufambiswa kwemagetsi: inenge 15.5% IACS (International Demagnetization Standard)

· Kuwedzerwa kwemutsetse: inenge 20.3 10^-6/K

Hunhu hwemakanika

Hunhu hweCuZn36 hunosiyana zvichienderana nemamiriro akasiyana ekupisa. Izvi zvinotevera mamwe emashoko akajairika ekushanda:

·Simba rekudhonza (σb): Zvichienderana nemamiriro ekupisa, simba rekudhonza rinosiyanawo, kazhinji pakati pe460 MPa ne550 MPa.

·Simba rekupa (σs): Zvichienderana nemamiriro ekupisa, simba rekupa rinosiyanawo.

·Kureba (δ): Waya dzine dhayamita dzakasiyana dzine zvinodiwa zvakasiyana pakureba. Semuenzaniso, kune waya dzine dhayamita iri pasi pe4mm kana yakaenzana, kureba kwacho kunofanira kusvika kupfuura 30%.

·Kuoma: Kuoma kweCuZn36 kunobva paHBW 55 kusvika 110, uye kukosha kwayo kunoenderana nemamiriro chaiwo ekupisa.

Zvimiro zvekugadzirisa

CuZn36 ine hunhu hwakanaka hwekugadzirisa zvinhu zvinotonhora uye inogona kugadziriswa nekugadzira, kuburitsa, kutambanudza uye kutenderedza zvinhu zvinotonhora. Nekuda kwehuwandu hwakawanda hwezinc, simba reCuZn36 rinowedzera nekuwedzera kwehuwandu hwezinc, asi panguva imwe chete, conductivity uye ductility zvinoderera. Pamusoro pezvo, CuZn36 inogonawo kubatanidzwa ne brazing uye soldering, asi nekuda kwehuwandu hwakawanda hwezinc, kutarisisa kwakakosha kunofanirwa kupihwa pakushongedza.

Kuramba ngura

CuZn36 ine simba rekudzivirira ngura mumvura, utsi hwemvura, munyu wakasiyana-siyana uye zvinwiwa zvakawanda zve organic. Yakakodzerawo munzvimbo dzepasi, dzegungwa uye dzemaindasitiri. Mune mamwe mamiriro ezvinhu, CuZn36 inogona kukonzera ngura inoputika mumhepo yeammonia, asi ngura iyi inogona kugadziriswa nekubvisa ngura yemukati muzviitiko zvakawanda.

Nzvimbo dzekushandisa
CuZn36 brass inowanikwa zvakanyanya muminda inotevera:

Uinjiniya hwemakanika: hunoshandiswa kugadzira zvikamu zvinoda kuomarara uye kuramba kupfeka, zvakaita semavharuvhu, zvikamu zvepombi, magiya nemabheringi.

Unyanzvi hwemagetsi: Nekuda kwekushanda kwayo zvakanaka kwemagetsi, inoshandiswa kugadzira zvinobatanidza magetsi, masoketi, nezvimwewo.

Kushongedza nemabasa emaoko: Nekuda kwehunhu hwayo hwakanaka hwekugadzirisa zvinhu uye ruvara rwayo rwakasiyana rwebhuranzi, CuZn36 alloy yakakodzerawo kugadzirwa kwezvinhu zvemaoko nemabasa emaoko.

CuZn36 ine mashandisirwo akasiyana-siyana, anosanganisira:

· Zvikamu zvakadzika

·Zvigadzirwa zvesimbi

·Indasitiri yemagetsi

· Zvinobatanidza

·Mainjiniya emakanika

·Zviratidzo nekushongedza

Zviridzwa zvemimhanzi, nezvimwewo.510

Sisitimu yekurapa kupisa

Sisitimu yekurapa kupisa yeCuZn36 inosanganisira annealing, quenching uye tempering, nezvimwewo. Nzira idzi dzekurapa kupisa dzinogona kuvandudza hunhu hwayo hwemakanika uye mashandiro ekugadzirisa.

Pfupiso:

Sechigadzirwa chemhangura chisingadhuri uye chinoshanda zvakanyanya, CuZn36 ine basa rakakosha mukushandiswa kwemaindasitiri. Inobatanidza simba rakawanda nekugona kugadziriswa zvakanaka uye yakakodzera kushandiswa kwakasiyana-siyana kweinjiniya, kunyanya kana ichiita zvikamu zvinoda hunhu hwakanaka hwemakanika uye kuramba ngura. Nekuda kwehunhu hwayo hwakanaka, CuZn36 ndiyo inonyanya kufarirwa mumaindasitiri mazhinji.

Tinokugamuchirai kuti mutibate kuti muwane rumwe ruzivo nezve machubhu emhangura kana emhangura!
