AlNiCo magnet is a kind of high-performance synthetic permanent magnet composing of metallic aluminum,nickel ,ferrocobalt and other metallic elements .According to different production modes,it can be divided into two types：casting and sintering. For casting type ,,different core sizes can be produced ,magnetic energy is high ,temperature coefficient for production is low; for sintering type ,generally ,it is defined as smaller size ,but mechanical strength is higher than casting type.
Compact crystallization ,high strength ,strong resistance to corrosion , composition uniformity ,excellent magnetic performance ,good temperature stability (Br temperature coefficient is the minimum among all kinds of permanent magnets ) maximum working temperature reaches 500℃, sintered magnet can be produced to be small volume ,complicated shape and built-up magnet .
Because of its temperature conditions is excellent (maximum operating temperature up to 500℃) low temperature coefficient ,high hardness and strong strength ,it is broadly applied in generator ,loudspeaker ,measuring instrument and other fields.
