| Material | Features uye Applications |
| Grey cast iron | Yakanaka fluidity, diki shrinkage rate panguva yekutonhora, kuderera simba, plasticity uye kuoma, elastic modulus inosiyana pakati pe80000 ~ 140000MPa ine akasiyana microstructures, compression simba iri 3 ~ 4 nguva yakakwirira kudarika simba rekusimba, kupfeka-kusagadzikana Zvakanaka pkuita uye vibration absorption.Haisi kunzwa kuchekwa uye ine yakanaka yekucheka kuita.Welding performance haina kunaka.Haikwanise kushandiswa kwenguva yakareba kupfuura 300 ~ 400℃.85% ~ 90% chiyero chezvigadzirwa zvesimbi. |
| Msimbi yakakandwa | Iko kuita kwekukanda kwakaipa kupfuura iyo yegrey cast iron uye iri nani pane iyo yesimbi yakakandwa.Inoshandiswa kugadzira zvidiki zvitete-madziro castings zvine zvimwe zvinodiwa zvekusimba uye kuoma.Good corrosion resistance uye yakanaka processing performance.Iko kuomarara kwekuita ndeye 3 ~ 4 nguva yakakura kupfuura iyo yegrey cast iron. |
| Ductile Iron | Iko kuita kwekukanda kwakaipa kupfuura iyo yegrey cast iron, uye inowanzoitika kune hurema.Kucheka kwekuita kwakanaka, uye kurapwa kwekupisa kunogona kuita kuti kushanda kwayo kuchinje mune zvakasiyana-siyana.Kusimba kwesimba rakakwirira kudarika resimbi yakakandwa nesimbi yakakandwa, uye chiyero chesimba regoho kusimba rekusimba rakakwirira kudarika simbi inoumbwa nesimbi.Iyo purasitiki ndiyo yakanyanya kunaka musimbi yakakandwa, uye kuomarara kwacho hakuna kunaka senge simbi, asi yakakura kupfuura iyo yegrey cast iron.Iine yakanaka yakaderera tembiricha kuita.Simba rekuneta rakakwirira, padyo nesimbi ye45, asi kunzwisiswa kwekunetseka kwekusimbisa kwakaderera pane kwesimbi.Kuramba kwakanaka kupfeka, kusamira kwekushisa uye kusagadzikana kwekuora.Iyo vibration attenuation ratio yesimbi, ductile iron uye grey iron ndeye 1:1.8:4.3.kuwedzera kushandiswa zvakanyanya sezvikamu zvakakosha. |
| Iron Yakasungirirwa Graphite | Iyo mechanic properties yevermicular graphite cast iron iri pakati pegrey cast iron uye ductile iron, uye ine yakanaka compactness, kupisa kupisa uye kupfeka kuramba.Kuita kwayo kwekukanda kuri nani pane iyo ye ductile iron uye padyo neiyo yegrey cast iron.Simba rayo rakafanana neiyo ductile iron, uye ine yakafanana anti-vibration, thermal conductivity uye kukanda zvinhu kune grey iron, asi zviri nani plastiki uye kuneta kuramba kupfuura grey iron.Yakasungirirwa graphite cast iron ichave ine imwe huwandu hwe nodular graphite.Kuwedzera kwenodular graphite kuchawedzera simba rayo uye kusimba, asi pamutengo wekukanganisa kugona kwekukanda kwesimbi yakanyungudutswa uye kushatisa kushanda uye kupisa kwemafuta ekukanda. |
| cast steel | Kuita kwekukandira kwakashata, kunyungudika kwakashata, uye shrinkage yakakura, asi ine yakakwira yakazara michina michina, ndiko kuti, simba repamusoro, kuoma uye plastiki.Kusimba simba uye kumanikidza simba zvakada kuenzana.Mamwe masimbi anokandwa ane akakosha midziyo yakadai seyekudzivirira kupisa uye kusaita ngura |
| Kanda aluminium alloy | Aluminium alloys anongova 1/3 kusimba kwesimbi uye anoshandiswa kugadzira akasiyana mwenje zvimiro.Mamwe maaruminiyamu alloys anogona kusimbiswa nekupisa kurapwa kuti ive nani akazara zvivakwa.Sezvo rusvingo rwemadziro runowedzera, simba rinoderera zvakanyanya. |
| ndarira yakaumbwa | Yakakamurwa kuita mapoka maviri: tin bronze uye Wuxi bronze.Tin bhuronzi ine kupfeka kwakanaka uye kusagadzikana kwekuora, kusimba kwepamusoro uye kuomarara, kusaita zvakanaka kwekukanda, uye kunowanzo kupatsanurwa uye kuderera.Kudzima hakuna simba rinosimbisa.Wuxi bhuronzi inowanzoshandiswa mualuminium bronze kana lead bronze, ine kusaita zvakanaka kwekukanda.Aluminium bhuronzi ine simba rakawanda, kusamira kwekusapfeka uye kusagadzikana kwekuora.Lead bronze ine simba rakanyanya kuneta, yakasimba yekupisa conductivity uye acid resistance |
| Kanda Brass | Yakakura shrinkage, kazhinji yakakwira simba, yakanaka plastiki, yakanaka corrosion resistance uye kupfeka kuramba.Kuita kwakanaka kwekucheka |
