Samarium Cobalt Magnet (SmCo magnet) manufacturers

Samarium Cobalt Magnet is one of the rare earth permanent magnets, made of the mixed materials of metal cobalt, samarium or praseodymium by melted crushed, pressured and sintered. EUKE MagTech Ltd is one of leading Samarium Cobalt ( SmCo magnet) manufacturers in China.
Manufactures SmCo5 and Sm2Co17 magnets with excellent quality.
- Accurate tolerance;
- Stable magnetic properties;

The advantages and features of SmCo5 & Sm2Co17 magnets
Compared with Sm2Co17, the properties of mechanical and ductility of Sm1Co5 is better. So Sm1Co5 is superior choice for the magnet that cannot be processed by Sm2Co17 material. Sm1Co5 materials is easier to process irregular-shape magnets. The operating temperature of the Sm1Co5 magnets can reach 250℃. Before designing, we suggest that users get some knowledge of the properties and characteristics of SmCo5 (1:5) and Sm2Co17 (2:17), and then choose reasonable and suitable samarium cobalt material.
 
For the thin wall or the thin thickness magnets, we recommend that customers to consider Sm1Co5 as material. The BH(max) of Sm2Co17 magnets are 20-32MGoe, which is slightly higher than SmCo5 magnets. Sm2Co17 magnets can bear operating temperature 350℃. Sm2Co17 magnets mainly are used in aerospace, automotive sensors, high temperature motor, microwave devices, military field because of low temperature coefficient, slightly stronger anti-corrosive quality. Sm2Co17 magnet is more brittle than Sm1Co5 magnet. So the magnets should be handled gently when install. Keep two magnets away or away from iron material in order to prevent the magnets damage or cracks.
 
Some users  magnetize by themself for their application. Please pay attention, Sm2Co17 magneta are hard to be fully magnetized than Sm1Co5 magnets. It needs greater magnetic field. Sm1Co5 magnets requires magnetic field about 40,000 gauss. The users should set up the magnetizing device according to the Samarium Cobalt material 1:5 and 2:17.
 
Plating: Compared with neodymium magnet, Samarium cobalt magnets have superior anti - corrosive and oxidation resistance. So usually it does not need coating. But if customer needs coating for nice appearance, it can be plated nickel, zinc, gold, or epoxy or other coating.
 
Magnetization direction: In addition to the normal magnetization direction, our company can manufacture SmCo magnets with axial multi-poles. The deviation of magnetization direction can be controlled between 2° -3°.
 
Application: Samarium cobalt magnets are widely used in medical equipment, apparatus, instrumentation, aerospace, defense industry, micro-wave devices, communications, sensors, magnetic processor, electrical, magnetic cranes, etc.
 
Properties for Samarium Cobalt Magnets
Euke MagTech Limited owns mature production technology and advanced equipments, can produce a variety of shapes and high-performance and stable performance of samarium cobalt products.

Sintered NdFeB Magnet - Neodymium Iron Boron Magnets

Introduction to Sintered NdFeB Magnet
Manufactured by EUKE MagTech Limited.
email:sales@cmsmagnets.com; www.cmsmagnets.com 

NdFeB magnet, i.e neodymium Iron Boron magnets is the most widely used rare earth magnet.

Because NdFeB magnet , also called “ neo ” or “neodymium “ is the strongest permanent magnet, and the operation temperature can be 150 -180 ℃ which can perform its best magnetic performance; In terms of Theory , NdFeB magnet working temperature can reach 200 ℃, in fact, it depend on the size, shape, working environment and magnetic circuit.  If need higher operation temperature , then considering Samarium Cobalt Magnet.

Secondly, neodymium magnets include variety of grades, is able to meet kinds of requirement of magnetic output performance and temperature ratings. So NdFeB magnet is very popular in kinds of application. The Grade is related with magnetic output and reversible temperature coefficients, so choosing grade is very important.

Neo magnet is composed of rare earth neodymium, metal praseodymium, iron, aluminum, boron-iron alloy, and other rare earth materials. The iron component make the neodymium magnet is easy to be rusty, so need make plating, usually, Nickel-copper-Nickel (NiCuNi) three layers protective coating. Also can make Zinc, Au (gold), Ag (silver), chromium (Chrome), epoxy (grey or black epoxy) plating.

Neodymium Magnet Application
Magnet for Motors &Generators
Magnet for Sensor
Magnet for Actuator
Magnet for Louder speaker
Magnet for Water treatment softener and conditioner
Magnet for Separators
Magnet for Electric industry

EUKE is able to produce kinds of shape magnets:

Disc Shape NdFeB Magnet , Ring shape magnet, Arc shape magnet , countersunk shape magnet and irregular shape magnet.

Radial Ring NdFeB Magnet

Compared with joint radial ring magnet, one – time molding radial ring magnet can improve the motor output, reduce loss of motor, and own better Temperature stability, particularly, be suitable for high precision driver, micro motor.

Customers complain the joint radial magnet is easy to fall off from bearing and arc assembly precision is low; to improve the disadvantage, EUKE have committed to develop and test one – time molding radial ring magnet for several years, is able to supply one - time molding radial magnet in batch, is widely used to sever motor, step motor and speed measuring motor.

Advantage of one – time molding Radial Ring NdFeB Magnet

Inside and outside ring ‘s tolerance can be + / - 0.05,  better coaxial degree and vertical degree;

Install directly and fast;

More stable;

Used on the rotor, obtained uniform distribution of magnetic flux density

Can be meet multi magnetization , such as skewed magnetization  , 

multi- pole magnetization, uni-pole magnetization

Still, radial ring NdFeB magnet is limited by size and Grade,

OD: Max. 70mm

ID: Min. 10mm,

Wall thickness: Min. 2mm
