AlNiCo

AlNiCo is the earliest developed a kind of permanent magnetic material, is made from aluminum, nickel, cobalt, iron and other trace metal elements of an alloy. According to different production process can be divided into Sintered AlNiCo, Sintered AlNiCo) and casting aluminum nickel and cobalt (Cast AlNiCo). Casting process can be processed into different size and shape; Compared with casting process, the sintering products is limited to small size, its production of blank size tolerance is better than blank casting products, magnetic is slightly less than the casting products, but it is better machinability. In the permanent magnetic material, casting aluminum nickel and cobalt permanent magnet has the lowest temperature coefficient is reversible, working temperature can be as high as 550 degrees Celsius above. Alnico permanent magnet products are widely used in all kinds of instruments, sensors and motor and aerospace, automotive industry and security systems, etc. More common are square, wafer, ring, water chestnut, round bar and suction, some of these can do spray paint processing.
