Alnico is an acronym for a family of iron-based magnet alloys which also contain aluminum (Al), nickel (Ni), cobalt (Co), hence, al-ni-co. This magnet material offers very good thermal stability and can be used at temperatures as high as 540 °C. Its residual induction (Br) is very high (up to 13.5 kG), but the intrinsic coercivity (Hci) is very low (typically from 550 to 2000 oersteds), therefore Alnico magnets can be easily demagnetized by external demagnetizing fields. Alnico magnets are resistant to corrosion and are good electrical conductors. KEY FEATURES OF ALNICO MAGNETS INCLUDE: High residual induction High operating temperature (540°C) Mechanically strong

Ceramic magnets, also known as hard ferrites or ferrite magnets, were developed in the 1950s. Although their maximum energy product (BH)max is only 1 to 4 MGOe, which is lower than other permanent magnets, Ceramic magnets have found many applications due to their attractively low price.KEY FEATURES OF CERAMIC MAGNETS INCLUDE: Least expensive magnets due to inexpensive raw materials and processes Very high electrical resistivity (around 106Ohm-cm) Positive reversible temperature coefficient of intrinsic coercivity

Neodymium iron boron magnets, also known as Nd2Fe14B magnets, neodymium magnets, neo magnets, Nd-Fe-B magnets, RE2TM14B magnets, or simply 2:14:1 magnets, were developed in the 1980s. Nd2Fe14B has a tetragonal crystal structure. The heavy rare earth element, dysprosium, is often added to increase intrinsic coercivity and maximum operating temperature. Small amounts of other transition metals, such as Al, Co, Cu, Nb andor Ga, can be added to modify the microstructure to improve performance.KEY FEATURES OF SINTERED NdFeB MAGNETS INCLUDE: Highest room temperature maximum energy product, (BH)max, up to 52 MGOe Relatively less expensive Wide range of choices for a variety of applications

Electron Energy Corporation’s samarium cobalt magnets (SmCo) have been the preferred material of choice since pioneering SmCo production in the 1970s. Because EEC controls every step of the material production from melting of the alloy to machining, we can deliver the highest performance SmCo in the industry. Our SmCo 33 grade of material is the highest performance product available today! SmCo is uniquely fit for high performance applications due to its high energy product (up to 33MGOe), performance across a wide-range range of temperatures (up to 550°C), resistance to corrosion, and resistance to demagnetization. KEY FEATURES OF SINTERED SMCO MAGNETS INCLUDE: Temperature Stability: highest operating temperature of 550°C Resistance to corrosion: highest corrosion resistant rare earth magnet material Highest resistance to demagnetization
