Feem ntau suav nrog cov hlau nplaum sib nqus (saib cov khoom sib nqus), elastic alloys, expansion alloys, thermal bimetals, hluav taws xob alloys, hydrogen cia alloys (saib hydrogen cia cov ntaub ntawv), zoo li nco alloys, magnetostrictive alloys (saib magnetostrictive cov ntaub ntawv), thiab lwm yam.
Tsis tas li ntawd, qee qhov tshiab alloys feem ntau suav nrog hauv qeb ntawm precision alloys nyob rau hauv cov ntaub ntawv siv, xws li damping thiab vibration txo alloys, stealth alloys (saib stealth cov ntaub ntawv), sib nqus kaw alloys, superconducting alloys, microcrystalline amorphous alloys, thiab lwm yam.
Precision alloys tau muab faib ua xya pawg raws li lawv lub cev sib txawv, xws li: cov hlau nplaum mos, deformed mus tas li sib nqus hlau nplaum, elastic alloys, expansion alloys, thermal bimetals, tsis kam alloys, thiab thermoelectric ces kaum alloys.
Feem ntau ntawm precision alloys yog raws li ferrous hlau, tsuas yog ob peb yog raws li cov hlau tsis-ferrous
Cov hlau nplaum sib nqus muaj xws li cov hlau nplaum mos thiab cov hlau nplaum nyuaj (tseem hu ua cov hlau nplaum ruaj khov). Tus qub muaj lub zog quab yuam tsawg (m), thaum tom kawg muaj lub zog loj (> 104A / m). Feem ntau siv yog cov hlau ntshiab, hluav taws xob hlau, hlau-nickel alloy, hlau-aluminium alloy, alnico alloy, tsis tshua muaj ntiaj teb cobalt alloy, thiab lwm yam.
Thermal bimetal yog cov khoom siv sib xyaw ua ke ntawm ob lossis ntau txheej ntawm cov hlau lossis cov hlau sib txawv nrog cov coefficients sib txawv uas muaj kev sib txuas ruaj khov rau ib leeg raws tag nrho qhov chaw sib cuag. High-expansion alloy yog siv los ua cov txheej txheem nquag, qhov qis-expansion alloy yog siv los ua cov txheej txheem passive, thiab ib qho interlayer tuaj yeem muab ntxiv rau hauv nruab nrab. Raws li qhov kub thiab txias hloov, cov thermal bimetal tuaj yeem khoov, thiab siv los tsim cov thermal relays, Circuit Court breakers, cov khoom siv hauv tsev pib, thiab cov kua thiab roj tswj li qub rau kev lag luam tshuaj thiab kev lag luam fais fab.
Cov khoom siv hluav taws xob muaj xws li cov hlau tsis muaj zog, cov khoom siv hluav taws xob, cov khoom siv thermocouple thiab cov khoom siv hluav taws xob, thiab lwm yam, thiab tau siv dav hauv cov khoom siv hluav taws xob, cov cuab yeej thiab cov ntsuas.
Magnetostrictive alloys yog ib chav kawm ntawm cov ntaub ntawv hlau nrog cov teebmeem magnetostrictive. Feem ntau siv yog hlau-raws li alloys thiab nickel-based alloys, uas yog siv los tsim ultrasonic thiab underwater acoustic transducers, oscillators, lim thiab sensors.
1. Thaum xaiv ib tug precision alloy smelting txoj kev, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog qhov zoo, qhov cub batch nqi, thiab lwm yam, feem ntau. Xws li yuav tsum tau muaj cov pa roj carbon tsawg tsawg tswj cov khoom xyaw, degassing, txhim kho purity, thiab lwm yam. Nws yog ib txoj hauv kev zoo tshaj plaws los siv cov hluav taws xob arc rauv ntxiv rau kev ua kom zoo rau sab nraum lub qhov cub. Raws li qhov kev xav tau zoo, lub tshuab nqus tsev vacuum induction tseem yog ib txoj hauv kev zoo. Txawm li cas los xij, lub peev xwm loj dua yuav tsum tau siv ntau li ntau tau.
2. Kev saib xyuas yuav tsum tau them rau kev siv thev naus laus zis los tiv thaiv kev sib kis ntawm cov hlau molten thaum lub sij hawm pouring, thiab kab rov tav nruam pouring muaj qhov tshwj xeeb tseem ceeb rau precision alloys.
