Alnico permanent magnet a metal alloy composed of alumuinum,nickel,cobalt,iron and other trace element composition.Alnico permanent magnet has two diffierent production processes:casting and sintering. Casting proces can be processed into different sizes and shapes;compared with the casting process,the sintered product confined to a small size,its production out of the rough size tolerance is better.Alnico has a strong anti-corrosion ability,the surface doesnot require plating
