SmCo Magnets

SmCo Magnets  yog ob tiam ntawm tsawg ntiaj teb  tas mus li hlau nplaum , yog ib tug high-muaj peev xwm ruaj khov magnet ua los ntawm Sm, Co, Fe thiab lwm yam txoj lw hlau ntsiab. Dhau li ib tug max ua hauj lwm kub ntawm 300 ℃, nws muaj zoo kawg li kuj tiv thaiv corrosion thiab oxidation. Li no, tej zaum nws yuav tsum tau siv nyob rau hauv aeronautic thiab qhov chaw lag luam aomng lwm tus neeg.

Manufactures  SmCo5  thiab  Sm2Co17  hlau nplaum nyob rau hauv ntau yam nrhiav. Muaj ntau cov neeg yuav tsum tau qib YXG28, YXG30, YXG32, SmCo28, SmCo30, SmCo32, etc.

Machining thiab tolerances

Peb tau dimensional loj thiab kam los txiav los yog sib tsoo nrog super ntxhib no los txhuam. Samarium Cobalt (SmCo) tsis tau av nrog pa drilling, tig los milling dab, thiab yuav tsum tau machined ua ntej lawv magnetized. Tsis tas li ntawd, loj los yog txoj kev sibtham no feem ntau yog magnetized ua ntej los ua ke. Standard tolerances rau Samarium Cobalt hlau nplaum yog +/-. 005 "rau hauv av qhov ntev. Peb Cov Stocks SmCo hlau nplaum nyob rau hauv block, nplhaib thiab disc daim ntawv nyob rau hauv ib tug ntau yam ntawm ntau thiab tsawg pab thiab cov grades, thiab peb yuav siab nruab los ua tus loj thiab kam hais tias koj yuav tsum tau.

1: 5 alloy khoom

1: 5 muaj 16 MGOe (zog khoom) rau 22 MGOe thiab yog ua los ntawm kwv yees li 50% samarium thiab 50% cobalt. Lub 1: 5 series muaj ib tug tshaj plaws pom zoo khiav hauj lwm kub ntawm 250 ° C. SmCo 1: 5 hlau nplaum yuav tsum tau sab teb txawj tshaj 2:17 ntaub ntawv rau magnetize. Nyob rau hauv ib co piv txwv, 1:15 khoom tej zaum yuav magnetized nrog ntau tug, muab hais tias ib tug magnetizing fixture yog muaj.

2:17 hlau cov ntaub ntawv uas

2:17 muaj 24 MGOe rau 32 MGOe thiab yog muaj li ntawm 25% samarium, 5% tooj liab, 18% hlau, 2% hafnium los yog zirconium, nrog rau cov uas tseem tshuav nyob cobalt. Cov 2:17 series ntawm muaj ib tug tshaj plaws khiav hauj lwm kub txog 350 ° C. Tshwj xeeb qib ntawm 2:17 yog muaj uas tau khiav lag luam mus txawm cia sov dua. SmCo 2:17 yuav tsum tau tsis tshua muaj neeg siab magnetizing teb, thiab ntau yam kev ncej magnetization yog tsis tau.

Nta: 
1. Zoo Coercity 
2. Zoo kub Stability 
3. Vim nqe rhiab heev ntawm cobalt, nws cov nqi yog kim thiab yooj yim rau ywj faj ywj fwm

Cov Txheej Txheem Ua ntawm Samarium Cobalt Permanent Magnet: 
Hmoov txheej txheem → Nias → Sintering → Sib Nqus vaj tse xeem → tej → tiav lawm cov khoom
Samarium cobalt ntaub ntawv no yog feem ntau ua nyob rau hauv un-magnetized tshwm sim, nrog pob zeb diamond zom log thiab ntub dej zoo sib tsoo, uas yog tsim nyog. Vim hais tias ntawm cov uas tsis muaj ignition kub, samarium cobalt yuav tsum tsis txhob qhuav kiag li. Cia li ib tug me me muaj los yog static hluav taws xob nyob rau hauv ntau lawm yuav yooj yim ua ib tug tua hluav taws, nrog tsis tshua muaj high kub, uas yog ib qho nyuaj rau tswj. 

Main muaj mob muaj nkees: 
Samarium cobalt hlau nplaum yog nkig. Thov kindly tiv thaiv koj lub qhov muag, cov ntiv tes thiab lub cev thaum soj ntsuam nrog lawv. 

Common applications

• High kev kawm motors
• Sib Nqus couplings
• Sib Nqus separators

SmCo Magnets VS Sintered Neodymium Magnets
Lub sib txawv ntawm SmCo hlau nplaum thiab Sintered NdFeB hlau nplaum mas muaj xws li cov ntsiab lus nram qab:
1. Sib Nqus quab yuam
Neodymium ruaj khov magnet    yog ntau haib tshaj SmCo magnet nyob rau hauv magnetic quab yuam.
(BH) Max ntawm sintered NdFeB yog li 53MGOe, thaum lub sij hawm (BH) Max ntawm SmCo khoom yog 32MGOe.
SmCo khoom yog tus muaj zog nyob rau hauv tsis kam demagnetization tshaj NdFeb khoom.
2. High kub kuj
NdFeB yog tsis superior li SmCo nyob rau hauv kub kuj. Qhov siab tshaj plaws ua hauj lwm kub ntawm NdFeB yog 200 ℃ thiab hais tias ntawm SmCo yog li 350 ℃.
3. Corrosion kuj
NdFeB hlau nplaum yog tsis yog li ntawd zoo nyob rau hauv tsis kam oxidation thiab corrosion. Feem ntau lawv yuav tsum tau muaj kev tiv thaiv los ntawm plating los yog txawm lub tshuab nqus tsev packing. Common hom txheej muaj xws li zinc, npib tsib xee, epoxy thiab lwm tus neeg. SmCo hlau nplaum yuav tsis tsum rusting tsis plating.
4. Zoo, ua thiab assembling
NdFeb thiab SmCo yog ob qho tib si taus cov ntaub ntawv uas, li ntawd, lawv yuav tsis tau manufactured los ntawm zoo tib yam tej ua.
Cov kev ua txoj kev yog hlau-electrode txiav thiab pob zeb diamond log tej. Yog li ntawd, producible rho los ntawm cov hlau nplaum no xwb. Nyuab heev nrhiav tsis workable. Kuj hais lus, SmCo khoom yog ntau yooj yim thiab yooj yim dua lov. Yog li ntawd, thov tau ceev faj heev nyob rau hauv assembling thiab siv SmCo hlau nplaum.
5. nqe
Ob peb xyoos dhau los, tus nqi ntawm SmCo hlau nplaum yog ob zaug los yog txawm ntau tshaj li uas ntawm NdFeB hlau nplaum.
Nyob rau hauv xyoo tsis ntev los, tus nqi ntawm NdFeB tau nce zoo heev vim teb chaws txoj kev txwv kev ntsuas nyob rau hauv tsawg lub ntiaj teb tsuas. Yeej, cov NdFeB hlau nplaum yog cheaper tshaj samarium cobalt.
