Kev nqis peev casting yog txheej txheem ntau yam uas tuaj yeem siv nrog ntau yam hlau thiab alloys. Nov yog qee cov hlau feem ntau siv hauv kev nqis peev casting:
Stainless hlau
Vim nws lub zog siab, zoo corrosion kuj thiab machinability, stainless hlau yog ib qho kev xaiv zoo heev rau peev casting. Nyob ntawm daim ntawv thov, cov qib sib txawv ntawm cov hlau tsis muaj steel yog siv, xws li 304, 316, 17-4 PH, 2205 duplex, thiab ntau dua. Qee qhov kev siv ntawm stainless hlau castings yog: marine hardwares, yeeb nkab fittings, automotive Cheebtsam, iav fittings, thiab lwm yam.
Carbon Steel
Carbon steel kuj yog ib qho khoom siv rau kev nqis peev casting. Piv txwv ntawm carbon steel alloys rau peev casting muaj xws li: AISI 1020, AISI 1030, AISI 1045, thiab lwm yam. Carbon steel yog siv rau nws txhua yam khoom nyob rau hauv ntau daim ntawv thov, xws li automotive Cheebtsam, industrial khoom thiab kev tsim kho.
Hlau alloy
Kev nqis peev casting feem ntau siv cov hlau alloy. Cov ntaub ntawv no suav nrog AISI 4140, AISI 8620, AISI 8630, thiab lwm yam. Cov ntaub ntawv no yog qhov sib npaug zoo ntawm lub zog thiab tawv. Alloy steel yog dav siv rau kev nqis peev casting ntawm qee yam khoom siv, xws li thoob cov hniav, cov khoom siv ua liaj ua teb, thiab lwm yam.
Nickel Raws li Alloys
Nickel raws li alloys, xws li Inconel los yog Hastelloy, yog siv nyob rau hauv peev casting txheej txheem uas muaj kub zoo heev thiab corrosion kuj. Vim nws cov ntsiab lus siab nickel, tus nqi ntawm cov nickel raws li alloy castings yog ntau dua stainless hlau castings. Nickel raws li alloys yog haum rau tsim cov cam khwb cia qhov chaw nyob rau hauv tshwj xeeb ib puag ncig, uas yuav tsum tau high corrosion kuj los yog kub kub kuj.
Aluminium Alloys
Aluminium alloys muaj ntau yam zoo, nrog rau lub teeb yuag, muaj zog thiab tiv taus corrosion. Cov alloys no kuj yooj yim rau cam khwb cia, thiab muaj ib tug zoo thermal thiab hluav taws xob conductivity. Lawv yog li perferred rau automotive thiab aerospace daim ntaub ntawv.
Tooj Alloys
Kev nqis peev casting yog feem ntau ua nrog tooj liab alloys xws li tooj liab thiab tooj dag. Cov ntaub ntawv no zoo rau kev tiv thaiv corrosion, thermal conductivity thiab zoo nkauj txaus siab.
Titanium alloys
Kev nqis peev casting yog siv los tsim cov titanium alloys rau cov ntawv thov uas xav tau lub zog siab, tsis muaj zog thiab corrosion kuj. Cov no suav nrog aerospace thiab kev kho mob kev lag luam.
Cov Hlau Hlau
Kev nqis peev casting tuaj yeem siv los tsim cov hniav nyiaj hniav kub thiab lwm yam khoom siv kos duab siv cov hlau zoo xws li kub lossis nyiaj.
Kev xaiv cov hlau siv hauv peev casting nyob ntawm qhov tshwj xeeb ntawm cov khoom tsim, nrog rau nws cov khoom siv kho tshuab, corrosion kuj, kub tsis kam, nqi, thiab lwm yam.
