Aluminium alloy, yog ib qho ntawm ntau yam khoom siv hauv ntiaj teb, tau siv ntau yam kev siv.Nws yog cov khoom siv rau ntau qhov kev lag luam vim nws yog lub teeb yuag, muaj zog, thiab corrosion-resistant.Kab lus no muab cov lus qhia dav dav rau aluminium alloy, nws cov ntaub ntawv raw, thiab ntau hom alloys muaj.
Raw Materials rau tsim Aluminium Alloy
Aluminium yog qhov thib peb tshaj plaws nyob rau hauv lub ntiaj teb crust, ua li 8% ntawm lub ntiaj teb crust los ntawm qhov hnyav.Nws yog tsuas yog tau los ntawm ob yam minerals: bauxite ore thiab cryolite.Bauxite ore yog lub hauv paus ntawm txhuas thiab yog mined nyob rau hauv ntau qhov chaw thoob ntiaj teb.Cryolite, ntawm qhov tod tes, yog cov ntxhia tsis tshua muaj nyob hauv Greenland.
Cov txheej txheem ntawm kev tsim cov aluminium alloy yuav txo tau cov bauxite ore rau hauv alumina, uas yog ces smelted nyob rau hauv lub cub tawg nrog carbon electrodes.Lub resulting kua aluminium yog ces ua rau ntau yam alloys.Cov khoom siv raw siv hauv kev tsim aluminium alloy muaj xws li:
1. Bauxite ore
2. Cryolite
3. Alumina
4. Aluminium oxide
5. Cov pa roj carbon electrodes
6. Fluorspar
7. Boron
8. Silicon
Hom ntawm Aluminium Alloys
Aluminium alloys raug cais raws li lawv cov tshuaj muaj pes tsawg leeg, lub zog, thiab lwm yam khoom.Muaj ob pawg tseem ceeb ntawm aluminium alloys: wrought alloys thiab cam khwb cia alloys.
Wrought alloys yog alloys uas yog tsim los ntawm dov los yog forging.Lawv siv nyob rau hauv daim ntawv thov uas lub zog, ductility, thiab formability yog qhov tseem ceeb.Feem ntau wrought alloys yog:
1. Aluminium-manganese alloys
2. Aluminium-magnesium alloys
3. Aluminium-silicon alloys
4. Aluminium-zinc-magnesium alloys
5. Aluminium-tooj liab alloys
6. Aluminium-lithium alloys
Cast alloys, ntawm qhov tod tes, yog cov alloys uas tsim los ntawm casting.Lawv yog siv nyob rau hauv daim ntawv thov uas yuav tsum tau intricate duab.Feem ntau cov cam khwb cia hlau yog:
1. Aluminium-silicon alloys
2. Aluminium-tooj liab alloys
3. Aluminium-magnesium alloys
4. Aluminium-zinc alloys
5. Aluminium-manganese alloys
Txhua aluminium alloy muaj nws tus kheej cov yam ntxwv, ua rau nws muaj txiaj ntsig zoo rau cov ntawv thov tshwj xeeb.Piv txwv li, aluminium-magnesium alloys yog lub teeb yuag thiab corrosion-resistant, ua rau lawv zoo tagnrho rau siv nyob rau hauv aircraft qhov chaw thiab automotive Cheebtsam.Aluminium-silicon alloys, ntawm qhov tod tes, yog cov cua sov kho thiab muaj kev hnav zoo, ua rau lawv zoo tagnrho rau siv hauv cov cav tov thiab pistons.
Xaus
Aluminium alloy yog cov khoom siv ntau yam uas siv rau ntau yam kev siv.Cov khoom siv raw siv hauv kev tsim aluminium alloy muaj xws li bauxite ore, cryolite, alumina, thiab carbon electrodes.Muaj ob pawg tseem ceeb ntawm aluminium alloys: wrought alloys thiab cam khwb cia alloys.Txhua aluminium alloy muaj nws tus kheej cov yam ntxwv, ua rau nws muaj txiaj ntsig zoo rau cov ntawv thov tshwj xeeb.Raws li kev siv thev naus laus zis, aluminium alloys yuav dhau los ua qhov tseem ceeb rau ntau yam kev lag luam, suav nrog aerospace, tsheb, thiab kev tsim kho.
