Lub rooj zaum fais fab, raws li cov cuab yeej tawm tshiab rau kev mus qeeb qeeb, tau maj mam lees paub los ntawm ntau tus neeg laus thiab cov neeg tsis taus.Yuav ua li cas peb yuav ibraug nqi hluav taws xob lub rooj zaum muaj log?

Raws li kev lag luam sab hauv rau ntau tshaj kaum xyoo, kuv xav luv luv pab koj daws qhov teeb meem no los ntawm ntau yam.Thawj qhov peb yuav tsum paub yog tias txhua pab pawg thiab cov neeg siv nws tus kheej qhov xwm txheej thiab kev siv ib puag ncig sib txawv, uas tseem ua rau muaj qhov sib txawv ntawm cov khoom yuav.

Cov khoom siv feem ntau yog muab faib ua carbon steel, aluminium alloy, aerospace titanium aluminium alloy thiab magnesium alloy, carbon fiber.

1. Cov khoom siv carbon steel.

Cov pa roj carbon steel thav duab feem ntau yog siv rau hauv cov rooj zaum hnyav hnyav thiab qee lub npe tsim los ntawm cov chaw tsim khoom me, cov rooj zaum hnyav hnyav siv cov ncej steel txhawm rau txhim kho lub zog ntawm lub cev thiab kev ruaj ntseg ntawm kev tsav tsheb, piv txwv li, ntau lub tsheb loj muaj steel ncej thiab lub tsheb me tuaj yeem siv txhuas yog tib yam vim li cas, cov chaw tsim khoom me tsim cov rooj zaum siv lub rooj zaum steel vim tias qhov kev ua haujlwm thiab vuam txheej txheem yuav tsum tau qis, tus nqi kuj tseem yog vim li cas cov chaw tsim khoom me siv steel ncej yog vim lawv xav tau kev ua haujlwm tsawg dua thiab vuam thiab yog pheej yig dua.

2. Aluminium & titanium-aluminium alloy

Aluminium alloy thiab titanium aluminium alloy, ob cov ntaub ntawv no yog feem ntau ntawm kev ua lag luam rau lub rooj zaum fais fab, lawv yog 7001 thiab 7003 ob hom aluminium, uas yog, txhuas nrog lwm cov khoom sib xyaw ntxiv rau nws, lawv cov yam ntxwv zoo sib xws yog tsawg ntom. thiab siab zog, zoo plasticity kuj thiab corrosion kuj, muab intuitively yog lub teeb thiab muaj zog thiab zoo ua, thaum titanium aluminium alloy yog tseem hu ua titanium-aluminium alloy vim nws lub zog thiab corrosion kuj.Raws li lub melting point ntawm titanium yog siab heev, ncav cuag 1942 degrees, uas yog ntau tshaj li 900 degrees siab tshaj kub, kev ua thiab vuam txheej txheem yog ib txwm nyuaj heev thiab tsis tau tsim los ntawm ib tug me me kev cog qoob loo, yog li lub rooj zaum log ua los ntawm titanium. -aluminium alloy yog kim dua.Cov qub yog tsim rau kev siv tsis tu ncua thiab txoj kev zoo thiab kev tsav tsheb, thaum cov neeg siv uas siv nws ntau zaus, feem ntau yuav tsum tau nqa nws, thiab feem ntau tsav tsheb ntawm lub qhov dej thiab txoj kev tsis sib haum tuaj yeem xaiv lub rooj zaum ua los ntawm titanium-aluminium alloy.

3. Magnesium alloy

Magnesium alloy yog raws li magnesium los koom nrog lwm cov ntsiab lus ntawm cov hlau.Nws cov yam ntxwv yog: qhov ceev me me, lub zog siab, muaj peev xwm tiv thaiv zoo li txhuas alloy, qhov feem ntau dav siv yog magnesium-aluminium alloy.Magnesium yog lub teeb tshaj plaws ntawm cov tswv yim hlau, nrog rau lub ntiajteb txawj nqus ntawm li ob feem peb ntawm txhuas thiab ib feem peb ntawm cov hlau, thiab siv magnesium rau lub rooj zaum logyog npaj kom ua tiav ntau "lightness" ntawm lub hauv paus ntawm aluminium.
