Aluminium Nickel Cobalt Magnetic Material And Its Application

Aluminum-nickel-cobalt (AlNiCo) was the first to develop a kind of permanent magnet material, is made of aluminum, nickel, cobalt, an alloy consisting of iron and other trace elements. Depending on the production process consists of sintered Alnico (Sintered AlNiCo) and cast Al-Ni-Co (Cast AlNiCo). Product shapes as round and square. Casting can be processed into different sizes and shapes compared with casting, confined to the small size of sintered products, which produced better than casting blank blank dimension tolerances, magnetic slightly below the casting product, but much better machinability. Permanent magnet material, cast Alnico permanent magnet has the best reversible temperature coefficient, the working temperature can be as high as 600 degrees Celsius. 20th century 30-60 's used, now used for the industrial manufacture of Magnetoelectric meter, flow meter, micro motor, relay, etc.
