Nws lub luag haujlwm hauv aluminium alloy ntau lawm yog qhov tseem ceeb hauv cov hauv qab no:
Deoxidizer:Raws li muaj zogdeoxidizer, silicon hlau 441 tuaj yeem tshem tawm cov pa oxygen thiab lwm yam oxides hauv lub pas dej ua ke aluminium alloy molten. Qhov no yog vim cov hlau silicon reacts nrog oxides los ua SiO₂, thiab silicon muaj ib tug siab solubility nyob rau hauv txhuas alloys, uas yuav sai sai txo oxygen mus rau SiO₂ thiab tso tawm nws tawm ntawm lub alloy, yog li txo cov seem ntawm oxygen nyob rau hauv lub alloy thiab txhim kho lub zoo thiab stability ntawm aluminium alloy.
Txhim kho lub fluidity thiab pouring zog ntawm aluminium:Qhov sib ntxiv ntawm silicon 441 tuaj yeem txhim kho qhov fluidity thiab pouring zog ntawm txhuas alloys, ua rau cov hlau yooj yim mus ntws thiab sau cov pwm thaum lub sij hawm casting txheej txheem, yog li txhim kho txoj kev zoo thiab nto tiav ntawm lub casting.
Ua kom muaj zog:Qhov sib ntxiv ntawm silicon hlau 441 rau txhuas alloys tuaj yeem tsim ib qho nyiaj ntawm cov khoom siv silicon, uas muaj cov txiaj ntsig tseem ceeb ntawm kev txhim kho lub zog tensile thiab hardness ntawm cov hlau. Cov khoom siv ntxiv dag zog rau cov nyhuv ntawm silicon hauv aluminium alloy ua rau cov alloy muaj zog dua thiab kub tsis kam nyob rau hauv qhov kub thiab txias, uas yog tsim rau kev siv hauv qhov chaw ua haujlwm kub.
Txhim kho corrosion kuj:Qhov sib ntxiv ntawm si 441 tuaj yeem txhim kho corrosion kuj ntawm aluminium alloy, ua rau cov alloy qhia zoo dua corrosion kuj nyob rau hauv ntau yam corrosive xov xwm thiab ncua kev pab cuam lub neej thiab stability ntawm lub alloy.
