SmCo Magnets

SmCo Magnets  di isa molokong o mong oa bobeli oa seoelo lefatše  magnets ka ho sa feleng , ke phahameng-bokgoni ho sa feleng makenete entseng ho tloha SM, Co, Fe le likarolo tse ling tse mosaletsa tšepe. Ntle le, max sebetsa mocheso oa 300 ℃, ho na le ho hanyetsa ka tsela e hlollang khahlanong ts'enyeho le ho kena moea. Ka lebaka leo, ho ka 'na sebelisoa ka aeronautic le sebaka liindasteri aomng bang.

Machining le tolerances

Re finyella tlhakore boholo le mamello ka ho seha kapa ho sila le abrasives bartolomeo. Samarium Cobalt (SmCo) e ke ke ya fatše le ho cheka tloaelehileng, ho retelehela kapa ho sila dithulaganyo, le tlameha ho machined pele ba magnetized. Ho phaella moo, likopanong tse khōlō kapa tse rarahaneng li hangata magnetized pele ho pokano. Standard tolerances bakeng Samarium magnets Cobalt ke +/-. Lewis 005 "bakeng sa litekanyo fatše. Re metšoasong magnets SmCo ka ea le literata, lesale le foromo disk ka mefuta e fapaneng ya boholo le limaraka, 'me re hlomeletsoe ka botlalo hore ba hlahise boholo le mamello hore u hlokang.

The 1: 5 letoto la lihlooho tse nang le palo e kahodimodimo kgothaletswa ho sebelisa mehaho mocheso oa 250 ° C. SmCo 1: 5 magnets hloka tlaase makhabane tšimo ho feta thepa 2:17 ho magnetize. Maemong a mang, 1:15 lintho tse bonahalang e ka magnetized le lipalo tse ngata, ha feela hore le tsobotsi magnetizing fumaneha.

• Likaroloana
• Process Production
• Main likotsi
• ho tloaelehile hore batho Kopo
• SmCo Magnets VS Sintered Neodymium Magnets

Motheong oa Magnetic Property: 
Boholo sebetsa mocheso: 250-350 ° C
Boholo Energy Product: (Bhmax) (15-35 MGOe) 
Boholo sebetsa Mocheso: (Temp.Tw) 250-350 
Induction Coercive Force: (Hcb) 4-12 (seko koe ) 
barrel matla a khoheli a: BR 0.8-1.2 (T) 
Reversible mocheso coefficient ea matla a khoheli a barrel (BR) -0.04 - -0,01

Features: 
1. Excellent Coercity 
2. Nice mocheso botsitso 
3. Ka lebaka tefello nahanela ya cobalt, theko ea eona e bitsa chelete e ngata ho le bonolo ho feto-fetoha

Production Process tsa Samarium Cobalt sa Feleng Magnet: 
phofo thulaganyou e → phehella → Sintering → Magnetic thepa teko → itšeha → o qetile lihlahisoa
Samarium cobalt thepa ka tloaelo sebetswa le tlas'a maemo a Machaba a Kopaneng-magnetized, le taemane sile lebili le metsi e metle sila, eo e hlokahalang. Ka lebaka la mocheso o tlase thothetsang molelo, samarium cobalt ha ea lokela ho ommeng ka ho feletseng. Feela tlhase nyenyane kapa motlakase ee sa fetoleng boemo tlhahiso ka habonolo tsosang mollo, le mocheso fetisisa phahameng, e leng le thata ho laola. 

Main likotsi: 
Samarium cobalt magnets ke brittle. Ka kopo, ka mosa sireletsa mahlo a hao, menoana 'me' mele ha re sebelisana le bona. 

Common applications

• Motors phahameng tshebetso
• couplings khoheli

SmCo Magnets VS Sintered Neodymium Magnets
The phapang pakeng magnets SmCo le magnets Sintered NdFeB haholo kenyeletsa lintlha tse latelang:
1. Magnetic lebotho la
Neodymium sa feleng makenete    o matla ho feta SmCo makenete e sebetsa matla a khoheli.
(Bh) Max oa NdFeB sintered ke ho fihlela ho 53MGOe, ha (bh) Max oa SmCo tse bonahalang ke 32MGOe.
SmCo lintho tse bonahalang e matla ho hanyetsa demagnetization feta NdFeb lintho tse bonahalang.
2. Phahameng mocheso hanyetsa
NdFeB hase phahametse ka SmCo ka mocheso ho hanyetsa phahameng. The lebetsoeng le sebetsa mocheso oa NdFeB ke 200 ℃ le hore ba SmCo ke ho fihlela ho 350 ℃.
3. ts'enyeho hanyetsa
NdFeB magnets ha e le molemo ho hanela ho kena moea le ts'enyeho. Ka kakaretso ba lokela ho ho sireletswa ka plating kapa esita le lephaka paka. Mefuta e tloaelehileng ea barbotage kenyeletsa zinki, nikele, epoxy le ba bang. SmCo magnets ke ke ho rusting ntle plating.
4. Shape, sebetsa le ho bokana
NdFeb le SmCo bobeli lintho tse bonahalang senyeha habonolo, kahoo ba ke ke ba ho etsoa ke ba tloaelehileng ho itšeha ho e lokisa.
The lokisa mokhoa kakaretso ke terata-eleketrode ho itšeha le taemane lebili ho itšeha. Kahoo dibopeho bo hlahisoang tsa magnets tsena ke e fokolang. Dibopeho tsena tse rarahaneng haholo ha ue boloke. Batlang e le bua, SmCo tse bonahalang ke feta senyeha habonolo le ho habonolo senya. Ka hona, ka kōpo ba ba hlokolosi haholo ka ho kopana le ho sebedisa SmCo magnets.
5. Price
A lilemo tse seng kae tse fetileng, theko ea magnets SmCo ne habeli kapa esita le ho feta hore ba magnets NdFeB.
Lilemong tsa morao tjena, theko ea NdFeB e tsohile haholo ka lebaka la ho mehato lithibelo Naha ka meepo seoelo-lefatše. Ha e le hantle, magnets tloaelehile hore batho ba NdFeB tse theko e tlaase ho feta samarium cobalt.
