Cov tsheb ciav hlau ceev ceev yog welded nrog txhuas, thiab qee qhov kev kub ceev tsheb ciav hlau hla dhau qhov chaw txias ntawm qhov kub ntawm 30 degrees Celsius; qee cov cuab yeej, cov cuab yeej siv thiab cov khoom siv txhua hnub ntawm Antarctic kev tshawb fawb nkoj yog ua los ntawm txhuas thiab yuav tsum tau tiv thaiv kev ntsuas qis rau caum-tsib degrees Celsius; qee qhov ntawm cov khoom siv ntawm cov tub lag luam nkoj los ntawm Tuam Tshoj los ntawm Arctic mus rau Tebchaws Europe kuj yog ua los ntawm txhuas, qee qhov raug tawm sab nraud, thiab qhov kub ntawm qhov nruab nrab kuj yog rho tawm 560 degrees Celsius;

Lawv puas tuaj yeem ua haujlwm ib txwm nyob hauv qhov chaw txias?

Cov lus teb yog 'Tsis muaj teeb meem, aluminium alloy thiab aluminium khoom yog qhov tsawg kawg ntshai ntawm txias thiab kub.

Aluminium thiab aluminium alloys yog cov khoom siv kub zoo tshaj plaws. Lawv tsis muaj qhov kub thiab txias brittleness. Lawv tsis yog kub-kub nkig li zoo tib yam hlau thiab npib tsib xee alloys. Lawv lub zog muaj zog nce nrog kub, tab sis plasticity thiab toughness ua raws. Qhov txo qis hauv qhov kub thiab txias yog txo, uas yog, muaj qhov kub thiab txias brittleness. Txawm li cas los xij, aluminium thiab aluminium alloys sib txawv heev, thiab tsis muaj ib qho ntawm qhov kub thiab txias brittleness. Tag nrho lawv cov khoom siv kho tshuab nce ntxiv nrog qhov txo qis ntawm qhov kub thiab txias, tsis hais txog ntawm cov khoom siv, txawm tias nws yog cam khwb cia aluminium alloy lossis deformed aluminium alloy, txawm tias nws yog hmoov metallurgy alloy lossis cov khoom sib xyaw; nws tsis muaj dab tsi ua rau lub xeev ntawm cov khoom, txawm tias nws yog nyob rau hauv lub xeev ua los yog nyob rau hauv lub tshav kub kho lub xeev; Nws tseem yog ywj siab ntawm cov txheej txheem kev npaj ingot, txawm tias nws yog dov los ntawm ingot los yog nruam nrum los ntawm yaj. Rolled los yog nruam dov; tsis muaj kev sib raug zoo nrog aluminium extraction txheej txheem, electrolysis, carbothermal txo, tshuaj extraction, tsis kub-kub brittleness; tsis muaj kev vam khom rau purity, seb nws yog 99.50% ~ 99.79% ntawm cov txheej txheem ntshiab txhuas, los yog 99.80% ~ 99.949% high-purity txhuas, 99.950% ~ 99.9959% ultra-purity txhuas (Super purity), 99.9960% ~ 99.9999% purity ,> 99.9990% ultra-siab purity aluminium, thiab lwm yam. Tsis tshua muaj kub brittleness.

Interestingly, lwm ob lub teeb hlau—magnesium thiab titanium—tsis muaj qhov kub thiab txias brittleness zoo li txhuas.
