A Sintered 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. They are generally the second-strongest type of magnet made, less strong than neodymium magnets, but have higher temperature ratings and higher coercivity. They are brittle, and prone to cracking and chipping. Samariumcobalt magnets have maximum energy products (BHmax) that range from 16 megagauss-oersteds (MGOe) to 32 MGOe, that is approx. 128 kJ/m3 to 256 kJ/m3; their theoretical limit is 34 MGOe, about 272 kJ/m3. They are available in two series, namely Series 1:5 and Series 2:17. SmCo Magnet (Sintered SmCo Magnet) is a high performance, low temperature coefficient permanent magnet with its high working temperature 350 degree centigrade. When working above 180 degree centigrade, SmCo Magnet (Sintered SmCo Magnet) maximum energy product BH and steady temperature are superior than NdFeB magnetic materials. SmCo Magnet (Sintered SmCo Magnet) neednt to be coated because it is difficult to be eroded and oxidized. Sintered SmCo is widely used in motors, watch, transducers, instruments, positional detector, generators, radar communications, medical equipments, various magnetism spreading devices, magnetic processor, electrical engineering and magnetic derrick. smco1smco2sm2co17

Alnico magnet is an acronym referring to a family of iron alloys which in addition to iron are composed primarily of aluminium (Al), nickel (Ni) and cobalt (Co), hence al-ni-co. They also include copper, and sometimes titanium. Alnico alloys are ferromagnetic, with a high coercivity (resistance to loss of magnetism) and are used to make permanent magnets. Before the development of rare earth magnets in the 1970s, they were the strongest type of magnet. Other trade names for alloys in this family are: Alni, Alcomax, Hycomax, Columax, and Ticonal. The composition of alnico alloys is typically 812% Al, 1526% Ni, 524% Co, up to 6% Cu, up to 1% Ti, and the balance is Fe. The development of alnico began in 1931, when T. Mishima in Japan discovered that an alloy of iron, nickel, and aluminum had a coercivity of 400 oersted (Oe) (32 kA/m), double that of the best magnet steels of the time. Alnico alloys make strong permanent magnets, and can be magnetized to produce strong magnetic fields. Of the more commonly available magnets, only rare-earth magnets such as neodymium and samarium-cobalt are stronger. Alnico magnets produce magnetic field strength at their poles as high as 1500 gauss (0.15 tesla), or about 3000 times the strength of Earths magnetic field. Some brands of alnico are isotropic and can be efficiently magnetized in any direction. Other types, such as alnico 5 and alnico 8, are anisotropic, with each having a preferred direction of magnetization, or orientation. Anisotropic alloys generally have greater magnetic capacity in a preferred orientation than isotropic types. Alnicos remanence (Br) may exceed 12, 000 G (1.2 T)[clarification needed], its coercivity (Hc) can be up to 1000 oersted (80 kA/m), its energy product ((BH)max) can be up to 5.5 MGOe (44 TA/m). This means alnico can produce a strong magnetic flux in closed magnetic circuit, but has relatively small resistance against demagnetization. Alnico alloys have some of the highest Curie temperatu
