Aluminum nickel cobalt (AlNiCo) is one of the earliest developed out of a permanent magnetic materials, is made of an alloy of aluminum, nickel, cobalt, iron and other trace elements. Aluminum nickel cobalt permanent magnetic material is developed in twentieth Century 30s. At that time, the best magnetic property, temperature coefficient is small, so in a permanent magnet motor, the most widely used the most. 60 years later, with the permanent magnetic ferrite and rare-earth permanent magnetic field, aluminum nickel cobalt permanent magnet application in motor replaced, the proportion decreased. mag-spring/neodymium-magnet/big-magnets.html 根据生产工艺不同分为烧结铝镍钴（Sintered AlNiCo）和铸造铝镍钴（Cast AlNiCo）。产品形状多为圆形和方形。铸造工艺可以加工生产成不同的尺寸和形状；与铸造工艺相比，烧结产品局限于小的尺寸，其生产出来的毛坯尺寸公差比铸造产品毛坯要好，磁性能要略低于铸造产品，但可加工性要好。在永磁材料中，铸造铝镍钴永磁有着最低可逆温度系数，工作温度可高达600摄氏度以上。铝镍钴永磁产品广泛应用于各种仪器仪表和其他应用领域。 According to the production process is divided into different sintering aluminum nickel cobalt (Sintered AlNiCo) and cast aluminum nickel cobalt (Cast AlNiCo). The product shape is circular and square. Production casting process can be processed into different sizes and shapes; compared with the casting process, the sintering products limited to small size, its production out of the blank dimension and tolerance than casting semifinished product is better, the magnetic energy was slightly lower than the casting products, but the processability. In permanent magnetic materials, cast AlNiCo magnets with low reversible temperature coefficient, operating temperature up to 600 degrees celsius. AlNiCo magnets are widely used in a variety of instrumentation and other applications.
