D0.25x0.125 inch Small disc smco magnet

Sintered smco disc magnet
Product Description
Samarium Cobalt (SmCo) magnet is made primarily from rare earth metal samarium and strategic metal cobalt, with iron, copper, zirconium and praseodymium. It has high performance and low temperature coefficient, the maximum working temperature is up to 350℃. It doesn't need to be coated because it is difficult to be eroded and oxidized, widely used in motor, sensor, meter, electronic, watch, automobile, aviation, aerospace and other applications. There are two alloy series for SmCo magnets: SmCo5 and Sm2Co17.
1.Grade:SmCo5 and Sm2Co17
SmCo Series 1:5
SmCo Series 1:5 has one atom of rare earth samarium and five atoms of cobalt. By weight this magnet alloy will typically contain 36% samarium with the balance cobalt. SmCo magnets generally have a reversible temperature coefficient of -0.05%. The maximum working temperature is about 350 ℃.
SmCo Series 2:17
SmCo Series 2:17 are age-hardened with a composition of two atoms of rare-earth samarium and 13-17 atoms of transition metals(TM).
The TM content is rich in cobalt, but contains other elements such as iron and copper.
Other elements like zirconium, hafnium, and such may be added in small quantities to achieve better heat treatment. By weight, the alloy will generally contain 25% of samarium. The maximum energy of these alloys ranges from 24 to 30 MGOe. SmCo magnets generally have a reversible temperature coefficient of -0.03% ℃. The maximum working temeprature is 300 ℃.
2.Shape:Ring(Design propermagnets for clients specific requirements)
3.Sorts:We haveDisc Smco Magnets,Segment Smco Magnets,Ring Smco Magnets,Block Smco Magnets,Cylinder Smco Magnets,Irregular Smco Magnets,Sintered Smco Magnets,Bonded SmCo Magnetsand many other series.
SmCo magnetshave better temperature stability and can be operated at higher temperature up to 300°C, while Nd-Fe-B magnets can not stand temperature over 200°C.Two types of SmCo magnets are SmCo5 and Sm2Co17.
The characteristics of Samarium Cobalt Magnet
*Very high magnetic properties with good stability.
*Superior resistance to high temperature, Curie temperature of majority is over 800°C
*Excellent corrosion resistance capability, no coating is needed for surface protection*High resistance to demagnetization
*High energy (magnetic strength is strong for its size)
*Good temperature stability
*Expensive material (cobalt is market price sensitive)
Applications of Samarium Cobalt Magnet
*Computer disc drives
