Dawb tooj liab cais
Cov tooj liab dawb
Copper-nickel binary alloy (xws li binary dawb tooj liab) yog hu ua dawb tooj liab. Hauv cov tooj liab dawb, tsab ntawv B qhia cov ntsiab lus ntawm npib tsib xee, xws li B5 qhia tias cov ntsiab lus npib tsib xee yog li 5%, thiab tus so yog hais txog cov ntsiab lus tooj liab. Cov qauv muaj xws li B0.6, B19, B25, thiab B30.
Muaj tooj liab dawb
Kev lag luam dawb tooj liab tau muab faib ua ob pawg: cov qauv dawb tooj liab thiab dawb tooj liab rau precision tsis kam alloy (hluav taws xob dawb tooj liab).
(1) Cov qauv tooj liab dawb: Cov qauv dawb tooj liab yog cov yam ntxwv ntawm cov khoom siv zoo thiab corrosion tsis kam, thiab xim zoo nkauj. Ntawm cov qauv dawb tooj liab, feem ntau siv yog B30, B10 thiab zinc dawb tooj liab. Tsis tas li ntawd, muaj txhuas dawb tooj liab, hlau dawb tooj liab thiab niobium dawb tooj liab. B30 muaj zog tshaj corrosion kuj ntawm cov tooj liab dawb, tab sis yog kim dua. Aluminium dawb tooj liab muaj qhov zoo sib xws rau B30 thiab pheej yig, yog li nws tuaj yeem siv los hloov B30. Zinc dawb tooj liab tau tsim thiab siv nyob rau hauv Suav teb txij li xyoo pua 15th thiab hu ua "Suav nyiaj". Cov nyiaj npib tsib xee lossis nyiaj German kuj tseem yog hom zinc dawb tooj liab. Zinc tuaj yeem yaj nyob rau hauv tooj liab thiab npib tsib xee hauv qhov ntau, ua kom muaj kev sib zog ua kom muaj zog thiab tiv thaiv corrosion. Zinc dawb tooj liab yuav smoothly txiav mus rau hauv ntau yam precision qhov chaw tom qab ntxiv txhuas, yog li nws yog dav siv nyob rau hauv cov twj paj nruag thiab cov cuab yeej kho mob. Cov hlau no muaj lub zog siab thiab corrosion kuj, zoo elasticity, zoo nkauj tsos thiab tus nqi qis. Cov txhuas hauv aluminium dawb tooj liab tuaj yeem txhim kho lub zog thiab corrosion kuj ntawm alloy, thiab nws cov precipitates tuaj yeem tsim los nag lossis daus. Cov qauv dawb tooj liab yog dav siv nyob rau hauv kev tsim cov precision machinery, tshuaj machinery thiab nkoj Cheebtsam.
(2) Dawb tooj liab rau precision kuj alloy (hluav taws xob dawb tooj liab): Dawb tooj liab rau precision kuj alloy (hluav taws xob dawb tooj liab) muaj zoo thermoelectric zog. BMn 3-12 manganese tooj liab, BMn 40-1.5 constantan, BMn 43-0.5 tooj liab thiab tshiab constantan nrog manganese es tsis txhob nickel (tseem hu ua npib tsib xee-dawb manganese dawb tooj liab, muaj 10. 8-12.5% manganese, 2.5-4.5% txhuas thiab 1.0-1.6% hlau) yog manganese dawb tooj liab nrog sib txawv manganese ntsiab lus. Manganese dawb tooj liab yog ib tug precision kuj alloy. Hom alloy no muaj siab resistivity thiab tsis tshua muaj kub coefficient ntawm resistivity, thiab yog haum rau ua tus qauv kuj ntsiab thiab precision kuj ntsiab. Nws yog cov khoom siv los ua cov cuab yeej hluav taws xob precision, rheostats, meters, precision resistors, strain gauges, thiab lwm yam. Constantan thiab tooj liab muaj peev xwm thermoelectric siab thiab tuaj yeem siv los ua cov thermocouples thiab cov nyiaj them poob haujlwm.
Qhov ntom ntawm cov tooj liab dawb: tooj liab dawb yog lub npe zoo nkauj rau tooj liab-nickel alloy, thiab nws qhov ntom yog nruab nrab ntawm tooj liab thiab npib tsib xee, 8.9--8.88
