As part of the rare earth group of permanent magnets, samarium cobalt (SmCo) magnets typically fall into two families of materials. They include rare earth Sm1Co5 and Sm2Co17 and are referred to as 1:5 and 2:17 materials. There're three different manufacturing processes: sintered SmCo magnet, bonded SmCo magnet, and injection moulding SmCo magnet. SmCo magnet is high performance, low temperature coefficient permanent made of samarium and cobalt and other rare-earth elements. Its biggest advantage is high working temperature-300 degree centigrade. It needn to be coated because it is difficult to be eroded
Features
- Samarium-Rare earth magnet sintered
- 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 vaccum. 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.
- Polymer Bonded SmCo magnet
- 1 It is an isotropic magnet with high magnetic properties.
- 2 It can be magnetized through any direction, suitable to make radial-magnetized or axially-magnetized multi-polar magnet.
- 3 It has high-precision dimension.
- 4 It has many types of shapes and specifications.
- 5 It is not easy to be eroded, due to advanced technology of surface.
- 6 environmentally morestable
- 7 lower temperature coefficient
- Injection Bonded SmCo Magnet
- The injection bonded SmCo magnet has a high mechanical strength and may be molded together with other matching parts. In all injection bonded SmCo magnet is produced with high efficiency, stability and repeatability; Magnet and other part may form together in one step. Injection bonded SmCo magnet is a functional material. It is unsuitable for structure part design. So the usual requirement to the tolerance of the dimensions for structure part is not applicable to it. injection bonded SmCo magnet has strong anticorruption function. So it needn't similar surface treatment as that of NdFeB magnet.
- Characteristics
- Having high dimensional precision; Versatile shapes and specification; Impact-resistant. Advanced surface treatment technology, effectively protect. Integrated forming
