Aluminium alloy tuaj yeem muab faib ua wrought aluminium alloy thiab cam khwb cia aluminium alloy raws li kev ua, lawv yog ob hom tseem ceeb ntawm aluminium alloys. Wrought aluminium alloy yog ib hom aluminium alloy uas dhau los ntawm stamping, dabtsi yog khoov, dov, extrusion thiab lwm yam txheej txheem txheej txheem, feem ntau yooj yim rau hauv cov yas, tseem hu ua siab ua txhuas alloy. Aluminium alloy casting yog ib hom aluminium alloy uas muaj cov hlau molten kom tau txais qhov seem ntawm ntau yam duab. Tsis tas li ntawd, lawv kuj txawv ntawm cov ntsiab lus no:
Cov khoom sib txawv
Wrought aluminium alloy yog tau los ntawm machining qhov chaw thiab qhov tseem ceeb tshaj plaws yog nws cov khoom siv kho tshuab, feem ntau yog txhuas phaj lossis pas nrig. Aluminium alloy casting yog nyob rau hauv daim ntawv ntawm cov kua kom tau qhov chaw, ntawm uas nws ntws kev ua tau zoo, shrinkage kev ua tau zoo, solidification hom yog cov feem ntau txhawj xeeb los ntawm cov neeg siv, tsuas yog rau txhuas worms;
Sib txawv alloy ntsiab
Ob leeg feem ntau muaj tib lub ntsiab lus alloying, tab sis nyob rau hauv sib txawv compositions thiab ntau, tshwj xeeb tshaj yog cov ntsiab lus Si. Qhov siab tshaj plaws feem pua ntawm silicon caij hauv cam khwb cia aluminium alloy yog siab dua li ntawm wrought aluminium alloy. Cov txheej txheem cam khwb cia yuav tsum tau hais tias ntxiv rau ntxiv dag zog rau cov ntsiab lus, ib qho txaus ntawm eutectic ntsiab (feem ntau silicon) yuav tsum muaj nyob rau hauv cov cam khwb cia txhuas alloy kom muab cov alloy ntau fluidity thiab yooj yim ntawm sau lub shrinkage pob qij txha ntawm lub casting.
Cov tswv ntawm cov khoom sib txawv
Cast aluminium alloy feem ntau muaj zog tensile qis, nws tsis tuaj yeem ua tiav siab precision vim nws muaj ntau yam sab hauv thiab sab nraud. Forged aluminium alloy muaj kev ua tau zoo thiab tuaj yeem siv rau kev tig, milling, drilling, npaj, sib tsoo thiab lwm yam kev ua haujlwm, tuaj yeem tau txais qhov tseeb qhov tseeb, tuaj yeem siv rau qhov tseeb.

Hauv cov ntsiab lus, cam khwb cia aluminium alloy muaj tus nqi qis dua ib kilogram thiab ntau cov duab vim qhov yooj yim casting, thaum wrought aluminium muaj cov khoom siv zoo dua, kev ua tiav, nto tiav thiab tuaj yeem siv rau kev siv high-end xws li aviation thiab aerospace teb. Kev ua yeeb yam sib txawv ua rau muaj kev sib txawv, cam khwb cia aluminium alloys yog dav siv hauv tsheb, kev ua liaj ua teb, thiab kev tsim kho kev lag luam xws li turbine blades, hubs, engine case, cylinder heads, transmissions and pistons, instrument casings and supercharger pumps, windows fittings and Agriculture equipment. Forged txhuas siv tau rau fuselages, tsaws iav qhov chaw, cav hniav, impellers, kiv cua, nrog rau cov khoom thiab cov khoom ntawm shipbuilding thiab kev lag luam.
