Aluminium tuag casting yog cov txheej txheem tsim khoom nrov siv los tsim ntau yam khoom hnyav thiab ruaj khov. Kev vam meej ntawm cov txheej txheem tuag casting feem ntau nyob ntawm cov khoom siv raw. Feem ntau ntawm cov tuag castings tsim thoob ntiaj teb yog tsim los ntawm aluminium alloys.

Silicon

Ib qho ntawm cov ntsiab lus tseem ceeb hauv aluminium tuag casting yog silicon. Silicon yog ntxiv rau aluminium alloys los txhim kho lawv cov fluidity, uas tso cai rau cov hlau molten tau yooj yim sau cov pwm nyuaj thiab tsim cov duab zoo nkauj. Silicon kuj pab txo qis shrinkage thiab txhim kho casting zog, xws li nto tiav thiab seem stability.

Tooj

Tooj liab yog lwm yam tseem ceeb hauv txhuas tuag casting. Copper txhim khu lub zog ntawm aluminium alloy, ua rau nws haum rau cov ntawv thov uas yuav tsum tau muaj zog thiab conductivity. Nws kuj tseem txhim kho corrosion kuj ntawm cov hlau, ua kom nws ruaj khov thiab kav ntev.

Magnesium

Magnesium feem ntau ntxiv rau aluminium alloys rau tuag casting lub hom phiaj. Nws pab txhawb rau cov khoom siv kho tshuab ntawm cov hlau, txhim kho nws lub zog thiab cuam tshuam tsis kam. Magnesium kuj txhim kho lub machinability ntawm cov alloy, ua kom yooj yim rau kev ua hauj lwm nrog thaum lub sij hawm tom qab casting txheej txheem.

Hlau

Hlau yog ib qho tseem ceeb hauv aluminium tuag casting. Nws pab txhim kho cov yam ntxwv ntawm cov hlau alloy thiab txhim kho nws cov hnav tsis kam. Hlau yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas cov khoom siv tuag-cam khwb cia yuav raug rau cov kev ntxhov siab siab lossis raug cuam tshuam rau ib puag ncig abrasive.

Manganese

Manganese feem ntau siv nyob rau hauv txhuas tuag casting los txhim kho lub zog thiab corrosion kuj ntawm alloy. Nws pab txhim kho tag nrho cov khoom siv kho tshuab ntawm cov khoom siv thiab ua rau nws tsim nyog rau cov ntawv thov uas xav tau ob qho tib si lub zog thiab kev tiv thaiv corrosion.

Zinc

Zinc yog lwm yam tseem ceeb hauv txhuas tuag casting. Nws pab txhim kho cov alloy cov khoom, xws li nws hardness thiab nto tiav. Zinc kuj tseem ua kom cov dej ntws ntawm cov hlau molten, tso cai rau kev tsim cov txheej txheem ntau dua thiab cov ncauj lus kom ntxaws.

Hauv kev xaus, cov khoom siv raw siv hauv txhuas tuag casting ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov khoom thiab kev ua tau zoo ntawm cov khoom kawg. Silicon, tooj liab, magnesium, hlau, manganese, thiab zinc yog cov ntsiab lus tseem ceeb uas ua rau tuag cam khwb cia aluminium alloy system. Los ntawm kev nkag siab txog lub luag haujlwm ntawm cov ntaub ntawv no thiab siv cov kev sib xyaw kom raug, cov neeg tsim khoom tuaj yeem ua tiav cov txiaj ntsig zoo ntawm lub zog, durability, thiab tag nrho cov khoom zoo.
