Yog tias koj tab tom nrhiav tungsten rau machining, shielding, counterweights, los yog siab -kub Cheebtsam, ib lo lus nug ntau yog: Puas yog tungsten magnetic? Cov lus teb luv luv yog: ntshiab tungsten tsis yog hlau nplaum zoo li hlau, tab sis nws tsis muaj zog paramagnetic. Qhov ntawd txhais tau hais tias nws tuaj yeem teb tau me ntsis rau qhov muaj zog sib nqus, tab sis nws tsis nyob hauv cov hlau nplaum tom qab tshem tawm. Qhov no tseem ceeb vim tias cov neeg yuav khoom feem ntau tsis meej pem tungsten ntshiab, tungsten carbide, thiab tungsten alloys, txawm tias lawv cov cwj pwm sib nqus tuaj yeem sib txawv heev.
Tungsten yog dab tsi?
Tungsten is a dense refractory metal with atomic number 74. It is well known for its very high melting point, high density, and strong performance in demanding industrial environments. Nyob rau hauv chav tsev kub, tungsten muaj qhov ceev ntawm li 19.3 g / cm³, thiab nws cov ntsiab lus melting yog li 3410-3414 degree, uas yog vim li cas nws yog dav siv nyob rau hauv tshav kub-cov khoom siv hluav taws xob, kev siv hluav taws xob, cov khoom siv hluav taws xob, hluav taws xob tiv thaiv, thiab hnav- cov cuab yeej tiv taus.
Puas yog Tungsten Sib Nqus?
Tungsten tsis yog ferromagnetic, yog li nws tsis coj zoo li cov hlau nplaum zoo li hlau, hlau, lossis npib tsib xee. Hauv kev siv tswv yim, feem ntau cov neeg yuav khoom thiab cov kws tsim khoom xav txog tungsten tsis yog - cov khoom siv hlau nplaum vim nws yuav tsis nyiam cov hlau nplaum los yog nyob twj ywm tom qab sib cuag nrog cov hlau nplaum. Kev tshawb fawb, txawm li cas los xij, tungsten yog cais raws li paramagnetic. Qhov no txhais tau hais tias nws tuaj yeem pom qhov kev nyiam me ntsis thaum raug cov hlau nplaum muaj zog, tab sis cov nyhuv tsis tshua muaj zog thiab ploj mus thaum lub teb raug tshem tawm. Vim li no, tungsten tsis tshua tau xaiv rau cov ntawv thov uas qhov kev ua haujlwm sib nqus tseem ceeb. Instead, it is more often chosen for its high density, excellent heat resistance, high melting point, and good mechanical stability in demanding industrial environments.
Pure Tungsten vs Tungsten Carbide vs Tungsten Alloy
Yog tias koj tab tom xaiv cov tungsten ntshiab, koj yuav tsum paub tias nws yog tsim los ntawm siab -purity tungsten hlau, feem ntau ua los ntawm tungsten hmoov thiab tom qab ntawd ua tiav rau hauv qhov ntom ntom. Hauv kev siv tswv yim, koj tuaj yeem kho cov tungsten ntshiab tsis yog -magnetic, txawm hais tias kev tshawb fawb nws tsis muaj zog paramagnetic thiab tsuas yog qhia me ntsis cov lus teb rau qhov chaw sib nqus.
Yog tias koj tab tom yuav tungsten carbide, cov khoom siv raw tsis yog cov hlau ntshiab tungsten. Nws feem ntau yog tsim los ntawm tungsten carbide nrog cobalt lossis npib tsib xee binder. Vim hais tias ntawm cov binder theem, ntau cemented carbides qhia ferromagnetic zog nyob rau hauv chav tsev kub, tab sis cov magnetic teb txawv raws qib.
Yog tias koj xav tau cov tungsten alloy, feem ntau nws yog tungsten- hnyav alloy ua nrog li 90% -97% tungsten nyob rau hauv ib tug npib tsib xee- hlau los yog npib tsib xee- tooj liab matrix. Nws cov hlau nplaum yog nyob ntawm cov txheej txheem hlau: qee cov qib tsis tshua muaj hlau nplaum, thaum lwm tus yog tsim los tsis yog -magnetic

Vim li cas tungsten tsuas yog Magnetic tsis muaj zog?
Tungsten qhov tsis muaj zog sib nqus teb los ntawm nws cov qauv hluav taws xob. Raws li cov khoom siv paramagnetic, nws muaj cov khoom siv hluav taws xob uas tuaj yeem kho me ntsis thaum muaj qhov sib nqus sab nraud. Tab sis thaum lub magnetic teb raug tshem tawm, cov nyhuv ntawd ploj mus. Hauv lwm lo lus, tungsten tsis khaws cov hlau nplaum, uas yog vim li cas nws txawv ntawm cov hlau nplaum zoo li hlau.
Cov ntawv thov tseem ceeb ntawm Tungsten los ntawm Kev Lag Luam
Tungsten yog siv nyob rau hauv ntau lub lag luam vim hais tias nws muaj ib tug tsawg ua ke ntawm siab ceev, tshav kub tsis kam, lub zog, thiab hnav kev ua tau zoo.
