H62 tooj dag yog dab tsi?
Brass H62 yog siv dav siv tooj liab alloy feem ntau tsim ntawm tooj liab (Cu) thiab zinc (Zn), nrog rau cov npe ntawm 62% tooj liab thiab 38% zinc. Paub txog nws cov khoom zoo heev, kev tiv thaiv corrosion, thiab zoo nkauj zoo nkauj, H62 tooj dag yog feem ntau siv rau ntau yam kev siv, xws li cov kav dej thiab hluav taws xob mus rau cov khoom dai. Kab lus no delves rau hauv cov qauv metallurgical, lub cev thiab tshuaj lom neeg, kev coj tus cwj pwm, thiab ntau yam kev siv H62 tooj dag, nrog rau kev sib tham ntawm nws cov txheej txheem ua, keeb kwm yav dhau los, thiab kev sib piv nrog lwm cov tooj liab -zinc alloys.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm tooj dag H62 yog tus cwj pwm los ntawm cov ntsiab lus tooj liab siab, nrog zinc ua lub ntsiab lus tseem ceeb alloying. Qhov sib xyaw ua ke yog kwv yees li 61.5% rau 63.5% tooj liab thiab cov zinc seem. Cov ntsiab lus xws li txhuas (Pb), hlau (Fe), thiab silicon (Si) tuaj yeem muaj nyob rau hauv feeb kom muaj nuj nqis, cuam tshuam cov alloy cov khoom me ntsis. Cov muaj pes tsawg leeg ntawm H62 yog tswj los ntawm cov qauv xws li GB / T 5231 hauv Suav teb, uas ua kom muaj kev sib haum xeeb hauv nws daim ntawv thov.
Metallurgical Structure
H62 tooj dag nthuav tawm ob theem -theem microstructure suav nrog (alpha) thiab (beta) theem. Lub -theem yog ib qho kev daws teeb meem ntawm zinc hauv tooj liab thiab yog qhov tseem ceeb hauv cov hlau. Nws muab ductility thiab corrosion kuj. The -theem, uas yog ib theem complex intermetallic, tshwm sim raws li zinc cov ntsiab lus nce. Hauv H62 tooj dag, -theem yog tam sim no nyob rau hauv cov khoom me me thiab pab txhawb rau cov alloy lub hardness thiab lub zog. Kev faib tawm thiab morphology ntawm cov theem no yog cuam tshuam los ntawm tus nqi cua txias thaum lub sij hawm solidification thiab tom qab kev kho cua sov txheej txheem.
Crystallographic qauv
Lub -theem ntawm H62 tooj dag muaj lub ntsej muag -centered cubic (FCC) qauv, uas yog ib txwm ntawm tooj liab thiab nws cov alloys. Cov qauv no tso cai rau kev ua haujlwm siab ntawm kev npleem thiab deformation, ua rau muaj qhov zoo ductility. Lub -theem, nyob rau hauv sib piv, muaj ib lub cev -centered cubic (BCC) qauv, uas yog tsawg ductile tab sis pab txhawb rau tag nrho cov alloy lub zog. Lub crystallographic orientation thiab grain loj ntawm cov theem no ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov khoom siv ntawm cov hlau.
Mechanical Properties
H62 tooj dag paub txog nws cov khoom siv kho tshuab zoo heev, uas suav nrog kev sib npaug zoo ntawm lub zog thiab ductility. Cov alloy muaj lub zog tensile xws li ntawm 300 mus rau 400 MPa, nrog rau elongation ntawm kev tawg ntawm li 40% mus rau 60%. Cov khoom no tuaj yeem tsim kho los ntawm ntau yam txheej txheem kho cua sov, xws li kev sib tsoo, uas tuaj yeem ua rau cov hlau mos thiab txhim kho nws txoj haujlwm. Lub hardness ntawm H62 tooj dag, feem ntau ntsuas ntawm Brinell nplai, tuaj yeem sib txawv raws li theem kev faib tawm thiab qib ntawm kev ua haujlwm txias nws tau dhau los.
Thermal Properties
Lub thermal zog ntawm H62 tooj dag yog tus yam ntxwv los ntawm nws cov thermal conductivity siab, uas yog lub cim ntawm tooj liab-raws li alloys. Lub thermal conductivity ntawm H62 tooj dag yog kwv yees li 120 W / m·K, ua rau nws tsim nyog rau cov ntawv thov uas cov cua kub dissipation yog ib qho tseem ceeb, xws li nyob rau hauv tshav kub exchangers thiab radiators. Cov hlau kuj tseem muaj cov coefficient nruab nrab ntawm thermal expansion, uas yuav tsum tau xav txog hauv cov ntawv thov uas muaj qhov sib txawv ntawm qhov kub thiab txias los tiv thaiv thermal stress thiab deformation.
Cov khoom hluav taws xob
H62 tooj dag muaj cov khoom siv hluav taws xob zoo, txawm tias nws qis dua li cov tooj liab ntshiab. Cov hluav taws xob conductivity ntawm H62 tooj dag feem ntau nyob ib ncig ntawm 28% IACS (International Annealed Copper Standard), uas yog txaus rau ntau yam khoom siv hluav taws xob thiab hluav taws xob, xws licov khoom sib txuasthiab terminals. Lub xub ntiag ntawm zinc, thaum txo qis cov conductivity piv rau cov tooj liab ntshiab, kuj tseem txhim kho cov alloy lub zog txhua yam, ua rau nws xaiv zoo dua rau cov khoom siv hluav taws xob thiab kev ua haujlwm zoo.
Corrosion Resistance
Kev tiv thaiv corrosion ntawm H62 tooj dag yog ib qho ntawm nws cov khoom muaj nqis tshaj plaws. Cov alloy muaj qhov ua tau zoo rau atmospheric corrosion, seawater corrosion, thiab ntau lwm yam. Lub -theem yog tshwj xeeb tshaj yog tiv taus corrosion, thaum lub sij hawm -theem yog me ntsis tsawg. Lub alloy tsis kam mus dezincification, ib daim ntawv ntawm corrosion qhov twg zinc yog xaiv leached tawm ntawm lub alloy, yog txaus rau feem ntau daim ntaub ntawv, txawm hais tias nws yuav xav tau kev tiv thaiv ntxiv nyob rau hauv ib puag ncig hnyav heev.
Daim ntawv thov
H62 tooj dag yog siv nyob rau hauv ntau yam kev siv vim nws zoo heev ua ke ntawm cov khoom. Hauv kev lag luam kav dej, nws yog siv rauvalves, fittings, thiab connectors vim nws corrosion kuj thiab formability. Hauv kev lag luam hluav taws xob, nws yog siv rau cov terminals, connectors, thiab lwm yam khoom uas yuav tsum tau muaj ob qho tib si txhua yam muaj zog thiab hluav taws xob conductivity. H62 tooj dag kuj tseem siv rau hauv kev tsim cov cuab yeej suab paj nruag, cov khoom siv kho kom zoo nkauj, thiab ntau yam khoom siv hauv tsev, vim nws cov tsos zoo nkauj thiab yooj yim ntawm fabrication.
