Taw qhia ntawm aluminium rod

Aluminium (Al) yog ib hom ntawm lub teeb hlau, nws cov tebchaw yog dav faib nyob rau hauv cov xwm, thiab cov peev txheej ntawm txhuas nyob rau hauv lub crust yog hais txog 400 mus rau 50 billion tons, thib ob tsuas yog oxygen thiab silicon, qeb thib peb. Nyob rau hauv cov hlau ntau yam rau thawj qeb ntawm hlau. Aluminium muaj cov khoom siv tshwj xeeb thiab lub cev, tsis tsuas yog lub teeb yuag, kev ntxhib los mos, tab sis kuj muaj cov ductility zoo, hluav taws xob conductivity, thermal conductivity, kub tsis kam thiab hluav taws xob tsis zoo, yog ib qho tseem ceeb raw khoom rau kev loj hlob ntawm lub teb chaws.
Aluminium yog ib qho khoom siv hlau nplua nuj nyob hauv lub ntiaj teb, thiab nws cov khoom khaws cia yog thawj ntawm cov hlau. Thaum kawg ntawm lub xyoo pua puv 19, txhuas tau tshwm sim los ua cov hlau sib tw hauv kev siv engineering thiab yog txhua qhov npau taws heev. Txoj kev loj hlob ntawm peb lub lag luam tseem ceeb, aviation, kev tsim kho thiab tsheb, yuav tsum muaj cov yam ntxwv ntawm cov khoom siv nrog cov khoom tshwj xeeb ntawm aluminium thiab nws cov alloys, uas txhawb kev tsim khoom thiab siv cov hlau tshiab no - txhuas.
