Tungsten vs Titanium

Taw qhia:

Tungsten thiab titanium yog ob hom hlau uas nrov siv hauv ntau qhov kev lag luam vim lawv cov khoom tshwj xeeb. Txawm hais tias ob qho tib si hlau siv zoo sib xws, lawv muaj qhov sib txawv ntawm qhov hnyav, tus nqi, lub zog, hardness, thiab compatibility nrog rhiab tawv nqaij. Hauv tsab xov xwm no, peb yuav muab qhov kev sib piv ntawm tungsten thiab titanium, pab cov neeg nyeem txiav txim siab seb cov hlau twg haum rau lawv cov kev xav tau zoo tshaj plaws.

Tungsten vs Titanium Nyhav

Tungstenmuaj qhov ntom ntawm 19.3 g / cm³, ua rau nws hnyav dua li titanium, nws qhov ceev yog 4.54 g / cm³. Qhov no txhais tau hais tias thaum siv tib lub ntim ntawm cov hlau, tungsten yuav hnyav dua titanium. Piv txwv li, ib qho 1-inch lub voos xwmfab ntawm tungsten yuav hnyav li ntawm 19 npaug ntau dua li 1-inch cube ntawm titanium.

Tungsten vs Titanium Nqe:

Tus nqi ntawm tungsten thiab titanium txawv nyob ntawm kev ua lag luam. Txawm li cas los xij, feem ntau hais lus, titanium nyiam tsawg dua li tungsten. Tus nqi tam sim no ntawm tungsten ntshiab yog nyob ib ncig ntawm $ 37 toj ib phaus, whereas ntshiab titanium tuaj yeem yuav tau nyob ib ncig ntawm $ 28 ib phaus. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tus nqi yuav txawv raws li qib purity thiab lwm yam xws li tus nqi muag khoom thiab qhov chaw.

Tungsten vs Titanium zog

Thaum muab piv lub zog ntawm ob lub hlau, tungsten siv lead ua. Nws Young's modulus yog kwv yees li 562 GPa, thaum titanium's Young's modulus zaum ntawm kwv yees li 165 GPa. Yooj yim muab tso, tungsten qhia pom lub zog tensile ntau dua li titanium nyob rau hauv kev ntxhov siab lossis elongation ua ntej tawg. Txawm li cas los xij, titanium muaj kev qaug zog zoo heev, txhais tau tias nws cov qauv tseem txhim khu kev qha txawm tias thaum lub sijhawm thauj khoom tas mus li. Tsis tas li ntawd, titanium tuav nws qhov zoo tshaj plaws nyob rau hauv ntau qhov kub thiab txias, tsis zoo li tungsten uas ua rau pom qee qhov poob hauv lub zog thaum cua sov dhau los ntawm 200 degree (392℉).

Tungsten vs Titanium Hardness:

Tungsten boasts ib lub siab tshaj plaws melting point ntawm tag nrho cov hlau, peaking ntawm 3422 degree (6192℉), thaum titanium muaj ib tug kuj tsawg melting point - 1668 degree (3304℉). Yog li ntawd, toughening tungsten yuav tsum muaj cov txheej txheem dav xws li alloying lossis ua haujlwm hardening es tsis yog kev kho cua sov raws li pom nyob rau hauv qee yam ferrous alloys thiab npib tsib xee.

Ntawm qhov tod tes, vim tias nws qhov kev tiv thaiv corrosion thiab qis dua piv rau cov hlau, tshwj xeeb tshaj yog hom stainless, ntau tus ntseeg tias cov titanium ntshiab yuav tsum tsis txhob siv cov cua sov zoo li carbon steels. Txawm li cas los xij, ob qho tib si tungsten carbide cemented carbides thiab cam khwb cia titanium feem ntau siv cov txheej txheem hardening ntxiv xws li nitriding. Nitride coatings txhim kho hnav lub neej yam tsis muaj kev cuam tshuam rau cov khoom siv los ntawm cov yam ntxwv ntau dhau.

Sensitive Skin Compatibility:

Tsis zoo li tungsten,titaniumua pov thawj tias yog hypoallergenic thiab tsis muaj tshuaj lom; Yog li, cov neeg uas muaj kev ntxhov siab ntau txaus siab rau kev nplij siab nyob ze ntawm cov khoom titanium. Qee cov tib neeg muaj kev cuam tshuam tsis zoo rau cov hniav nyiaj hniav kub ua los ntawm cov hlau tshwj xeeb xws li npib tsib xee pom nyob rau hauv cov khoom kub dawb, tab sis feem ntau pom muaj qhov sib npaug biocompatible lwm txoj hauv kev siv cov ntsiab lus rov ua dua tshiab lossis cov txheej txheem kuaj muaj niaj hnub no, suav nrog nyiaj cadmium oxide & rhodium plated rau liab tooj liab substrate lossis lwm tus uas muaj cov nyiaj ntau txog li ntau txhiab qhov ib lab Pdmax.

 Although the human body generally tolerates tungsten well enough so long as no exposure occurs through ingestion or skin irritation resulting from sharp edges/points over extended periods, those concerned about potentially sensitive skin would still benefit more from choosing items featuring primarily (>99 feem pua).

Daim ntawv thov:

Vim nws lub zog-rau-qhov sib piv thiab zoo corrosion kuj,titaniumPom cov ntawv thov dav dav hauv cov tshuab dav hlau, cov chaw tsim khoom lag luam, cov khoom siv hauv hiav txwv, cov khoom siv phais mob, cov khoom siv ua kis las (cov koom haum ntaus golf & ntaus pob tesniv), saib cov rooj plaub, cov khoom tsim cov hniav nyiaj hniav kub, cov tsom iav qhov muag, thiab cov khoom siv tsheb - tshwj xeeb tshaj yog cov tshuab pa.

Ntawm qhov tod tes, vim nws qhov hnyav heev tiv thaiv abrasives, tungsten pom kev ua haujlwm feem ntau yog qhov ua tau zoo heev ua qhov tseem ceeb: tub rog mos txwv cores, X-ray lub hom phiaj hauv cov khoom siv kho mob, teeb filaments, txiav cov cuab yeej & cov khoom hnav-tiv taus. Superalloys kuj tau txais txiaj ntsig los ntawm tungsten qhov ntxiv vim nws ua rau lawv lub zog kub heev. Cov ntawv thov superalloy no suav nrog cov roj turbine hniav rau lub zog tsim hluav taws xob, cov khoom siv dav hlau dav hlau rau kev lag luam dav hlau lossis chaw nres tsheb, cov tshuaj cog reactors / cua sov exchanger tubing nyob rau hauv ib puag ncig corrosive heev raug ncaj qha rau molten sulfuric acid vapor / kua tee - tag nrho cov cheeb tsam yuav tsum tau txhim kho qhov kub thiab txias stability. nrog phenomenal dimensional kev ncaj ncees.

Xaus:

Tom qab tshuaj xyuas cov kev sib piv saum toj no ua tib zoo, cov kws tshaj lij tuaj yeem txiav txim siab seb puas yogtungsten los yog titaniumua tau zoo nyob rau hauv ntau yam ntsiab lus. Txawm li cas los xij, kev txiav txim siab ntawm lawv los ntawm ntau lub hom phiaj es tsis nug dab tsi zoo li lub hom phiaj zoo tshaj plaws. Xav txog tej yam xws li kev txwv nyiaj txiag, xav tau lub zog piv rau qhov xav tau qhov hnyav txo cov kev ntsuas coj mus rau hauv tus account nrog rau cov xwm txheej ib puag ncig tau ntsib thiab kev nyiam ntawm lub cev yog tias tsim nyog. Ua ke lawv yuav tsum coj peb txoj kev xaiv kom meej rau ib qho khoom siv tsis yog lwm qhov thaum twg cuam tshuam tshwj xeeb nrog ob cov hlau no thiab ntau yam kev xav tau nthuav tawm los ntawm cov haujlwm sib txawv ntawm peb txoj kev lag luam.
