4000 Series Aluminium Phaj Sheet-Al-Si Alloy

4000 series txhuas ntawv: tus neeg sawv cev yog 4A01.4000 series txhuas daim hlau yog cov series nrog cov ntsiab lus ntau dua silicon.Feem ntau cov ntsiab lus silicon yog nyob nruab nrab ntawm 4.5-6.0%.Nws belongs rau lub tsev cov ntaub ntawv, mechanical qhov chaw, forging cov ntaub ntawv, vuam cov ntaub ntawv;Tsawg melting point, zoo corrosion kuj Cov lus piav qhia: Nws muaj cov yam ntxwv ntawm kev ua kom sov thiab hnav tsis kam.

4000 series aluminium alloys yog aluminium alloys nrog silicon ua lub ntsiab alloying.Feem ntau ntawm nws cov alloys yog kub-kho tsis muaj zog aluminium alloys.Tsuas yog cov alloys uas muaj Cu, Mg thiab Ni, nrog rau cov alloys ntxiv dag zog los ntawm kev kho cua sov, tuaj yeem nqus tau qee yam ntsiab lus.Nws tuaj yeem ua kom muaj zog los ntawm kev kho cua sov.Vim muaj cov ntsiab lus ntawm silicon siab, tsis tshua muaj melting point, zoo yaj ntws, yooj yim noj thiab tsis brittleness ntawm cov khoom kawg, series ntawm alloys no mas siv nyob rau hauv lub tsim ntawm aluminium alloy welding additives xws li brazing daim hlau, electrodes thiab nyob ntawm tej.Cov hlau muaj qhov hnav tsis zoo thiab cov khoom kub kub, thiab tseem siv rau hauv kev tsim cov pistons thiab cov khoom kub-resistant.Cov alloy uas muaj li 5% silicon yog dub-grey tom qab anodizing thiab xim.

Piv rau 4Y32, 4032 aluminium alloy muaj cov ntsiab lus qis alloying, tab sis muaj cov khoom siv tau zoo thiab lub zog tensile siab tshaj plaws ntawm 4000 series alloys.Lub hauv paus silica gel loj yog tsawg dua 70μm thiab yog siv dav hauv kev tsim cov pistons thiab lwm yam kev pabcuam kub kub vim nws cov khoom tshwj xeeb.

4Y32 aluminium alloy muaj cov ntsiab lus siab dua ntawm cov ntsiab lus alloy ntau dua li 4032 series, thiab muaj lub zog zoo dua thiab hnav tsis kam.Qhov loj ntawm tus thawj silicon yog tswj ntawm 30-40μm.Vim nws cov khoom tshwj xeeb, nws tau siv dav hauv kev tsim khoom ntawm txhua yam khoom siv thiab cov khoom siv uas siv rau qhov kub thiab txias, xws li cov tshuab cua txias, cov khoom siv peripheral.
