Hauv kev lag luam niaj hnub, kev xaiv ntawm cov khoom ua si yog lub luag haujlwm tseem ceeb hauv kev ua haujlwm, tooj liab (tooj liab (tooj liab. Hauv daim ntawv no, peb yuav siv ib-qhov tob saib qhov kev sib xyaw ua ke ntawm Cuzn15 BRASS cuam tshuam rau nws cov kev cia siab rau nws cov ntawv thov hauv ntau daim teb.
1. Qhov muaj pes tsawg leeg ntawm cuzn15 tooj dag thiab nws cov cawv ntawm kev ua tau zoo
Cuzn15 tooj dag nyob rau cov kab mob zinc tsawg, thiab nws lub ntsiab tshuaj muaj yees muaj raws li hauv qab no:
Tooj (CU): 84. 0% {2}}. {}}}%
Zinc (ZN): Residual (txog 14. {{{% {% {2}}}}}}%)
Lead (PB): Tsawg dua lossis sib npaug rau 0. 05%
Hlau (FE): tsawg dua lossis sib npaug rau 0. 05
Tin (sn): tsawg dua lossis sib npaug rau 0. 1%
1.1 cov nyhuv ntawm zinc (zn) cov ntsiab lus ntawm cov khoom
Cuzn15 piv rau High-Zinc Brass (xws li cuzn30, cuzn40), nws cov ntsiab lus zinc qis dua (14% {%), uas muaj ntau yam cuam tshuam rau kev ua haujlwm ntawm cov khoom siv:
Txhim kho corrosion resistance: cov ntsiab lus zinc tsawg txo qhov kev pheej hmoo ntawm tooj dag, ua rau muaj kev haum rau kev siv tshuaj, cov khoom siv marine thiab sab nraum zoov.
Txhim kho cov yas thiab duclity: Qinc Brass muaj qhov zoo dua li cov txheej txheem siab dua li cov txheej txheem sib sib zog nqus thiab khoov, thiab yog siv dav hauv kev tsim khoom thiab cov ntaub ntawv sib sib zog.
Saib xyuas hluav taws xob siab: vim nws cov ntsiab lus tooj liab dua, cuzn15 muaj cov hluav taws xob ntau dua li cov khoom siv hluav taws xob, cov ntaub ntawv tiv thaiv thiab txuas hluav taws xob.
1.2. Cawv ntawm cov kab ntu ntawm cov khoom
Lead (PB): Lw cov thawj coj (tsawg dua lossis sib npaug rau 0. Kev tsim kho kev ua haujlwm thiab pab rau machines ua haujlwm.
Hlau (FE): Cov ntsiab lus hlau tswj tau tsawg dua lossis sib npaug rau 0. 05%}.
Tin (SN): Ib qho me me ntawm Tin (tsawg dua lossis sib npaug ntawm 0. 1%) tuaj yeem txhim kho rau cov tooj daj, ua kom haum rau ntub dej lossis tshuaj lom neeg.
2. Lub cev thiab cov kws kho tshuab ntawm cuzn15 tooj dag
2.1 Cov Khoom Siv Lub Cev
Cov khoom siv lub cev ntawm cuzn15 tooj dag ua rau nws cov khoom zoo rau engineering, electronics thiab kev tsim kho:
Ntom ntom: 8.75 g / cm³
Melting taw tes: ≈ 900 - 940 degree
Hluav taws xob conductivity: kwv yees. 38% ICS (International Analealed Tooj Liab Qauv Qauv)
Thermal conductivity: kwv yees. 120 w / mk
Coefficient ntawm thermal expansion: 20 x 10- ⁶ k-¹
Nws lub siab thermal thiab hluav taws xob conductivity ua nws qhov kev xaiv zoo rau cov hluav taws xob, kev hloov pauv kub thiab cov ntaub ntawv ua kom sov.
2.2. Cov Khoom Siv Neeg Kho Tshuab
Tom qab ua haujlwm txias lossis tsim nyog kho cua sov, cuzn15 nthuav qhia cov khoom siv kho tshuab zoo heev:
Tensile Lub Zog (RM): {300 - 400 mpa mpa
Paib lub zog (rp 0. 2): ntau dua los yog sib npaug rau 150 MPA
Elongation (A50): Ntau dua lossis sib npaug rau 30%
Hardness (HBW): 90 - 120
Piv nrog cov high zinc brass, cuzn15 muaj qhov zoo dua thiab ductility, thiab haum rau qhov uas yuav tsum tau zoo machinability.
3. Cuzn15 tooj dag daim ntawv thov thaj chaw
Vim tias Cuzn15 ua si muaj lub zog siab, corrosion tsis kam thiab ua haujlwm tau zoo heev, nws tau siv dav hauv ntau yam kev lag luam. Hauv qab no yog nws cov ntaub ntawv thov tseem ceeb thiab kev txhim kho yav tom ntej.
3.1 hluav taws xob thiab hluav taws xob kev lag luam
Daim Ntawv Thov:
Hluav Taws Xob Txuas Hluav Taws Xob thiab cov chaw tsim hluav taws xob: Cuzn15 lub siab ua rau nws yog cov khoom zoo rau cov khoom hluav taws xob tsawg thiab hluav taws xob.
Cov Khoom Siv Hluav Taws Xob: Cov Khoom Siv Hluav Taws Xob: Kev ua haujlwm zoo heev thiab kev ua haujlwm tiv thaiv kev ua rau nws siv rau hauv cov khoom siv thaiv hluav taws xob xws li lub xov tooj ntawm tes thiab cov khoos phis tawj.
Yav Tom Ntej:
Nrog rau kev txhim kho ntawm 5g kev sib txuas lus, internet ntawm tej yam (iot) thiab cov khoom siv hluav taws xob ntau ntxiv, thiab CUZN15 yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv daim teb no.
3.2. Aerospace thiab Precision Raug
Daim Ntawv Thov:
High-precision ntsuas ntsuas: siv hauv kev tsim cov khoom siv ntsuas kev ua si, cov ntsuas thiab ntsuas ntsuas.
Satellite thiab Aerospace Cov Khoom Siv Hluav Taws Xob: Raws li cov khoom siv corrosion thiab corrosion-resistant cov khoom, cuzn15 yog siv nyob rau hauv lub dab dej sov thiab hluav taws xob hluav taws xob tiv thaiv cov ntaub ntawv.
Yav Tom Ntej:
Nrog cov kev hloov kho ntawm qhov chaw thev naus laus zis, qhov kev thov rau Cuzn15 hauv kev siv avionics thiab qhov chaw tshaj tawm yuav loj hlob ntxiv.
