Kis cov rooj sibtham feem ntau yog ua los ntawm cov hlau xws li txhuas alloy, hlau, thiab tooj liab.
1. Alloy Alloy
Cov tsev tuaj kis tau yog feem ntau ua los ntawm txhuas alloy vim tias ntawm lawv lub teeb yuag, muaj zog, cov yam ntxwv uas tau raws li qhov yuav tsum tau ua los sib dhos.
Tej yam alloys alloys suav nrog 6061 thiab 356 - Tsis muaj lub zog ua rau muaj zog thiab cov khoom siv kub ua tau zoo. Cov no alloys muaj feem ntau siv hauv cov tsev xa khoom tuaj yeem siv, roj lauj kaub, lub dab dej kub, thiab lwm qhov ntawm cov txheej txheem hloov chaw.
2. Hlau
Cov khoom sib xyaw tseem ceeb hauv kev sib sau ua ke, xws li lub zog, bearings, thiab clutches, yog feem ntau ua los ntawm cov hlau. Hlau lub siab tawv thiab muaj zog hnav tsis kam yog qhov tseem ceeb heev rau kev ntseeg tau thiab lub sijhawm hloov pauv ntawm cov rooj sib tham.
Cov ntaub ntawv tshwj xeeb, cov ntaub ntawv steel siv rau hauv kev sib sau ua ke suav nrog cov me me roj carbon hlau, nruab nrab} cov hlau carbon, thiab aluminoy alloy. Txhua cov khoom muaj nws tus kheej cov yam ntxwv tshwj xeeb thiab siv hauv kev tsim cov khoom sib txawv.
3. Tooj
Tooj liab yog cov hlau hluav taws xob hnyav rau ob qho hluav taws xob thiab cua sov, thiab yog li ntawd siv hauv kev sib tim sib dhos xws li hluav taws xob sib xyaw thiab cov hluav taws xob. Tooj liab kuj muaj cov tshuaj tiv thaiv corrosion zoo heev thiab cov yas, ua kom cov kev xav tau rau cov khoom siv no.
Ntxiv rau cov hlau xws li aluminium alloys, hlau, thiab tooj, cov rooj sib tham thiab cov rooj sib tham kuj tseem tuaj yeem siv lwm cov ntaub ntawv, xws li plastics thiab roj hmab. Cov ntaub ntawv no feem ntau yog siv rau hauv cov ntsaws ruaj ruaj, kev nqus kom tsis zoo, thiab lwm qhov chaw ntawm lub rooj sib txoos hloov chaw.
