AlNiCo permanent magnet is an alloy composed of metal aluminum, nickel, cobalt, iron and other trace elements. Due to different production processes, AlNiCo magnet can be separated as cast alnico magnet and sintering alnico magnet. AlNiCo permanent magnets have strong anti-corrosion ability and good temperature stability. The highest working temperature can reach 550℃, and do not need surface treatment.
