Dab tsi yog Aluminium Bronze Alloys
Aluminium bronze yog ib tsev neeg ntawm tooj liab-raws li alloys nyob rau hauv uas txhuas yog lub ntsiab alloying caij, feem ntau 4 mus rau 12 feem pua, feem ntau ua ke nrog hlau, npib tsib xee, thiab manganese. Kev sib xyaw ua ke tsim cov ntaub ntawv nrog lub zog tensile mus txog cov qauv hlau, zoo heev tiv thaiv dej hiav txwv thiab tshuaj lom neeg corrosion, thiab kev hnav zoo heev. Vim hais tias ntawm cov khoom no, txhuas bronzes yog dav teev nyob rau hauv marine engineering, hnyav machinery, aerospace, thiab tshuaj lom neeg kev lag luam.
Qib Tsev Neeg thiab Kev Sau Npe

| C62300 | Wrought | 8.5-10.0 feem pua | Fe 2.0-4.0 feem pua |
| C63000 | Wrought | 9.0-11.0 feem pua | Ni 4.0-5.5 feem pua, Fe |
| C63200 | Wrought | 8.5-9.5 feem pua | Ni, Fe, Mn |
| C95200 | Ntxig | 8.5-9.5 feem pua | Fe 3.0 feem pua |
| C95400 | Ntxig | 10.5-11.5 feem pua | Fe 3.0-5.0 feem pua |
Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm
Thoob plaws hauv tsev neeg, aluminium bronzes qhia ntau yam kev coj cwj pwm.
Lub zog siab thiab qaug zog ua haujlwm, haum rau kev thauj khoom -cov kabmob.
Zoo heev tiv thaiv dej hiav txwv corrosion, yaig, thiab cavitation.
Zoo hnav tsis kam nrog cov coefficient tsawg ntawm kev sib txhuam ntawm cov hlau.
Kev ruaj ntseg ntawm qhov kub siab, nrog rau kev nkag siab zoo nyob rau hauv kev txhawb nqa.
Kev tiv thaiv oxidation thiab rau ntau qhov chaw tshuaj lom neeg, suav nrog dilute acids.
Xaiv Wrought piv rau Cast Qib
Wrought qib xws li C61300 thiab C61400 ua ke nruab nrab txhuas nrog hlau thiab manganese kom xa cov khoom sib npaug rau phaj, pas nrig, thiab raj. Lawv yog siv rau nkoj fasteners, marine hardware, twj tso kua mis shafts, thiab tshav kub exchanger Cheebtsam. C63000 thiab C63200 ntxiv npib tsib xee rau lub zog siab dua thiab nyiam dua rau hnyav-cov dej hiav txwv dej hiav txwv, cov kav dej, thiab cov khoom tsaws iav. Cam khwb cia qib C95200 thiab C95400 yog teev rau lub cev twj tso kua mis, impellers, lub zog, thiab cov kabmob loj qhov chaw nyob ze ntawm -net-puab casting txo nqi machining.
Daim ntawv thov los ntawm Kev Lag Luam
Shipbuilding thiab marine engineering: kiv cua, rudder qhov chaw, seawater piping, thiab fittings.
Offshore platforms thiab cua turbines: siab -load, corrosion- tiv taus cov yam ntxwv.
Aerospace: bushings, bearings, thiab tsaws iav kho vajtse.
Cov khoom siv tshuaj lom neeg thiab roj av: cov khoom siv valve raug rau cov xov xwm corrosive.
Heavy machinery: iav, hnav daim hlau, thiab zawv zawg nto.
Txoj Cai Tswjfwm
Wrought aluminium bronze phaj thiab ntawv yog them los ntawm ASTM B171, pas nrig thiab bar los ntawm ASTM B150, thiab forgings los ntawm ASTM B283. Castings yog muab rau ASTM B148. EN cov npe rau cov qib sib xws suav nrog CuAl7Si2 thiab CuAl10Fe3, nrog rau EN 1652 thiab EN 1982 cov qauv.
Cov lus nug nquag
Q: Vim li cas aluminium ntxiv rau tooj liab hauv cov alloys?
A: Aluminium ntxiv dag zog rau tooj liab matrix thiab tsim cov oxide zaj duab xis tiv thaiv dej hiav txwv thiab tshuaj lom neeg corrosion.
Q: Qib twg yog qhov zoo tshaj plaws rau kev pabcuam dej hiav txwv?
A: C61300 thiab C61400 yog ib txwm siv rau cov dej hiav txwv wrought, thaum C95800 cam khwb cia npib tsib xee- txhuas bronze yog dav siv rau cov kiv cua thiab twj tso kua mis impellers.
Q: Puas tuaj yeem aluminium bronze welded?
A: Yog, nrog rau cov khoom siv hlau zoo xws li txhuas bronze electrodes lossis hlau thiab tswj preheat rau cov ntu tuab.
Q: Ua li cas aluminium bronze piv nrog stainless hlau hauv marine siv?
A: Aluminium bronze resists crevice thiab pitting corrosion zoo thiab tsis txhob galling nyob rau hauv zawv zawg sib cuag, thaum muab ntau dua thermal conductivity.
Q: Cov ntawv twg muaj nyob?
A: Phaj, ntawv, pas nrig, bar, raj, forgings, thiab castings, rau ASTM B171, B150, B283, thiab B148.
Q: Puas yog aluminium bronze magnetic?
A: Tsis yog, nws yog qhov tseem ceeb tsis yog -magnetic, uas haum rau kev ntsuas thiab kev siv hluav taws xob.
