| SmCo5 MagnetsSmCo1:5 magnet is also named SmCo5, which is prorated with metallic samarium, cobalt and metallic praseodymium. The (BH) max range is from 16 to 25, maximum working temperature 250°C. The physical character and ductibility of SmCo5 is better than Sm2Co17, so SmCo5 is slightly easier to be machined with complex shapes and thin thickness of disc or ring, while Sm2Co17 is more brittle. Magnetization magnetic field of SmCo5 is lower co***red with Sm2Co17. In general, SmCo5 can be magnetized saturated by 4000Gs magnetic field, however, magnetizing Sm2Co17 with high Hcj value need more than 6000Gs magnetic field. For some reasons, the price of SmCo5 is more expensive than Sm2Co17. According to different applications and using requirements, customer can choose SmCo5 or Sm2Co17 reasonably. .A samarium–cobalt (SmCo) magnet, a type of rare earth magnet, is a strong permanent magnet made of an alloy of samarium and cobalt. They were developed in the early 1970s, by Albert Gale and Dr. Daas, of Raytheon Corporation. They are generally ranked similarly in strength to neodymium magnets, but have higher temperature ratings and higher coercivity. They are brittle, and prone to cracking and chipping. Samarium–cobalt magnets have maximum energy products (BHmax) that range from 16 megagauss-oersteds (MGOe) to 33 MGOe, that is approx. 128 kJ/m3 to 264 kJ/m3; their theoretical limit is 34 MGOe, about 272 kJ/m3.Attributes-Extremely resistant to demagnetization- Good temperature stability (maximum use temperatures between 250 °C (523 K) and 550 °C (823 K); Curie temperatures from 700 °C (973 K) to 800 °C (1,070 K)- Expensive and subject to price fluctuations (cobalt is market price sensitive)Physical and mechanical propertiesCo***rison of physical properties of sintered neodymium and Sm-Co magnetsPropertyNeodymiumSm-CoRemanence (T)1�.30.82�.16Coercivity (MA/m)0.875�.990.493�.59Relative permeability1.051.05Temperature coefficient of remanence (%/K)�.12�.03Temperature coefficient of coercivity (%/K)∠|
