Sintered SmCo Magnet/SmCo magnet/SmCo ring magnet
Key Features:
1. The most excellent temperature characteristics in Rare Earth magnet family since MID-1960s;
2. Manufactured by a powder metallurgical process which involves the sintering of powder under vacuum. As part of rare earth group of magnets, SmCo magnets typically fall into two families of materials. They include SmCo5 and Sm2Co17, and commonly referred to as 1: 5 and 2: 17 materials;
3. Good corrosion resistance and no special surface treatment is required, which makes SmCo an excellent choice for compact designs where high temperature environments my be present;
4. Grinding and slicing can be operated into the desired shape and size.
Application:
Acoustics, motors, MRI, electron, electrical computer, machining, measuring meter, oil, metallurgical industrial and so on.
Shape:
All kinds of permanent materials such as squares, rounds, rings, tiles, bars, polygons can be supplied according to customer's requirements.
