6063-T5 architectural aluminium profiles yuav tsum muaj qee yam khoom siv. Hauv lwm qhov xwm txheej zoo ib yam, nws lub zog tensile, yield zog nrog kev nce hauv cov ntsiab lus thiab nce. 6063 Taiwan kub reinforced theem yog feem ntau Mg2Si theem, thaum kawg, Mg, Si thiab Mg2Si npaum li cas yuav tsum tau npaum li cas zoo? Mg2Si theem yog tsim los ntawm 2 magnesium atoms nrog silicon atom, magnesium tus txheeb ze atomic mass ntawm 24.3l, silicon tus txheeb ze atomic mass ntawm 28.09, yog li Mg2Si Nyob rau hauv lub compound, qhov sib piv ntawm magnesium rau silicon yog 1.73: 1.
Yog li ntawd, raws li cov txiaj ntsig ntawm cov kev ntsuas saum toj no, yog tias magy-silicium cov ntsiab lus piv txwv li 1.73, muaj ib qho dhau ntawm magnesium, thiab vice versa, tus piv Yog tsawg dua 1.73, nws qhia tau tias silicon ntxiv rau kev tsim ntawm MG2SI theem, muaj qhov muaj txiaj ntsig ntawm silicon.
Tshaj magnesium yog teeb meem rau cov khoom siv kho tshuab ntawm cov hlau. Magnesium feem ntau tswj tau ntawm {{0}}.5% lossis li ntawd, tag nrho cov nyiaj Mg2Si tswj ntawm 0.79%. Thaum cov silicon ntau dhau 0.01% ntawm cov khoom siv hluav taws xob ntawm cov hlau σb txog 218Mpa, tau zoo heev dhau lub teb chaws tus qauv kev ua tau zoo, thiab cov silicon ntau dhau ntawm 0.01% mus rau 0.13%, σb tuaj yeem nce ntxiv rau 250Mpa, uas yog, nce ntawm 14.6%. Txhawm rau tsim ib qho nyiaj ntawm Mg2Si, yuav tsum xub coj mus rau hauv tus account Fe thiab Mn thiab lwm yam impurities tshwm sim los ntawm kev poob ntawm silicon, uas yog, kom ntseeg tau tias muaj qee qhov nyiaj ntau ntawm silicon. Txhawm rau ua kom 6063 alloy magnesium tag nrho txuam nrog silicon, cov khoom xyaw tiag tiag, yuav tsum paub ua kom Mg: Si<1.73. Magnesium excess not only weaken the strengthening effect, but also increase the product cost.
Yog li ntawd, muaj pes tsawg leeg ntawm 6063 alloy feem ntau tswj raws li nram no: Mg: 0.45% -0.65%; Si: 0.35% -0.50%; Mg: Si=1.25-1.30; impurities Fe tswj hauv<0.10% -0.25%; Mn <0.10%.
