aluminium
Aluminiumyog ib tug silver-dawb lub teeb hlau. Feem ntau ua rau cov pas nrig, nplooj ntawv, ntawv ci, hmoov, ribbons thiab filaments. Nyob rau hauv huab cua ntub, ib qho oxide zaj duab xis tuaj yeem tsim los tiv thaiv hlau corrosion. Cov hmoov txhuas thiab txhuas ntawv ci tuaj yeem hlawv hnyav thaum cua sov hauv huab cua thiab emit dazzling dawb nplaim taws. Yooj yim soluble hauv dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide thiab potassium hydroxide daws, tab sis insoluble hauv dej. Tus txheeb ze ntom ntom 2.70. Melting point 660 degree. Kub taw tes 2327 degree.
Aluminiumyog ib qho tshuaj lom neeg; nws lub cim yog Al thiab nws tus lej atomic yog 13. Txhuas yog tsawg dua li lwm yam hlau, txog li ib feem peb ntawm cov hlau. Nws muaj kev sib raug zoo rau cov pa oxygen thiab tsim cov txheej txheem oxide tiv thaiv ntawm qhov chaw thaum raug huab cua. Aluminium zoo ib yam li nyiaj hauv ob qho tib si xim thiab muaj peev xwm los cuam tshuam lub teeb. Nws yog mos, tsis-magnetic thiabtuaj yeem.

Ntshiab aluminiumyog mos heev, tsis muaj zog heev, thiab muaj ductility zoo. Nws tuaj yeem kos rau hauv filaments thiab dov rau hauv foils. Nws yog dav siv nyob rau hauv kev tsim cov xov hlau, cables, xov tooj cua kev lag luam, thiab kev lag luam ntim khoom. Nws cov hluav taws xob conductivity yog kwv yees li ob feem peb ntawm tooj liab, tab sis vim nws qhov ceev tsuas yog ib feem peb ntawm tooj liab, piv rau txhuas cov xov hlau thiab tooj liab ntawm qhov sib npaug ntawm qhov loj thiab qhov ntev, aluminium qhov hluav taws xob conductivity yog hais txog tooj liab ob npaug ntawm tooj liab, thiab cov tus nqi qis dua qhov tooj liab. Yog li ntawd, teb high-voltage xov hlau feem ntau yog ua los ntawm txhuas, uas txuag tau ntau tus nqi thiab txo qhov nro ntawm cov khoom siv tooj liab.
Lub thermal conductivity ntawm txhuas yog peb npaug ntau dua li ntawm cov hlau. Aluminium feem ntau yog siv rau hauv kev lag luam los ua ntau yam khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam. Ntau cov khoom siv ua noj siv hauv tsev kuj yog ua los ntawm txhuas. Nws tseem tsis tshua muaj kev cuam tshuam rau xeb ntau dua li hlau, ncua nws lub neej kev pab cuam.
Hauv kev lag luam metallurgical, thermite feem ntau yog siv los smelt refractory hlau. Piv txwv li, yog tias cov hmoov txhuas thiab hlau oxide hmoov sib xyaw ua ke, cov tshuaj tiv thaiv hnyav yuav tshwm sim tom qab qhov tshwm sim. Qhov no feem ntau yog siv los vuam rails hauv kev thauj mus los; aluminium feem ntau yog siv los ua deoxidizer hauv kev lag luam steelmaking; Cov ntawv txhuas du muaj lub teeb pom kev zoo thiab tuaj yeem siv los tsim cov khoom zoo Reflectors, condenser tais, thiab lwm yam. Txhuas kuj muaj cov suab nrov zoo. Raws li qhov tshwj xeeb no, aluminium yog siv hauv qee chav tshaj tawm thiab cov qab nthab hauv cov tsev loj niaj hnub.
