Khoom siv rau Tuag Casting
Cov ntaub ntawv tseem ceeb uas siv hauv kev tuag casting muaj xws li tin, lead, zinc, aluminium, magnesium, thiab tooj liab. Zinc thiab aluminium alloys yog siv dav tshaj plaws, ua raws li magnesium thiab tooj liab alloys. Tam sim no, zinc, aluminium, thiab magnesium alloys yog cov khoom siv tseem ceeb hauv kev lag luam hluav taws xob.
Tuag Casting Zinc Alloy
Zinc alloys muaj fluidity zoo heev nyob rau hauv lub xeev molten thiab ib tug tsawg melting point ntawm tsuas yog 365 degrees Celsius. Lawv tuaj yeem tau txais ntau yam kev tshaj tawm - kev kho mob, xws li electroplating. Yog li ntawd, lawv muaj ntau yam kev siv. Lawv tau siv yav dhau los hauv kev lag luam xov tooj ntawm tes, tab sis vim lawv qhov loj me thiab tsis zoo corrosion kuj, lawv tau maj mam phased tawm los ntawm aluminium alloys. Daim ntawv thov feem ntau yog nyob rau hauv chav dej fixtures kev lag luam.
Tuag Casting Aluminium Alloy
Aluminium alloys muaj qhov ntom ntom, tab sis kuj muaj zog, nce los yog siab tshaj qhov siab - zoo steel. Lawv muaj cov yas zoo thiab tuaj yeem ua rau ntau yam profiles. Lawv muaj cov hluav taws xob zoo heev thiab thermal conductivity thiab corrosion kuj, thiab yog dav siv nyob rau hauv kev lag luam, thib ob tsuas yog steel nyob rau hauv cov nqe lus ntawm kev siv. Aluminium alloys muaj qhov hnyav tshwj xeeb tsuas yog ib feem peb ntawm cov hlau, ua rau lawv tseem ceeb hauv ntau qhov kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem sib sib zog nqus ntawm dav hlau, nkoj, tsheb, thiab khoom siv hluav taws xob.
Tuag-Ntaus Magnesium Alloys
Magnesium alloys yog cov hlau uas muaj magnesium ua lub hauv paus thiab lwm yam khoom. Their characteristics include: low density, high specific strength, high specific modulus of elasticity, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloys, and good resistance to corrosion from organic substances and alkalis. Magnesium qhov tshwj xeeb lub ntiajteb txawj nqus yog kwv yees li ob -feem peb ntawm txhuas thiab ib qho -quarters ntawm hlau. Yog li ntawd, nws yog dav siv hauv xov tooj ntawm tes, khoom siv sib txuas lus, cov khoom siv tsheb, thiab cov khoom siv kho mob.
