Alnico Permanent Magnets are made from an alloy of aluminum, nickel, and cobalt, with possible additions of iron, copper, and titanium. The Alnico 9 series represents the highest performance grade, offering exceptional temperature stability, strong magnetic force, and superior corrosion resistance.
These magnets can be magnetized in any direction (axial, radial, or multi-pole), making them versatile for applications including generators, microphones, and measuring instruments. With a maximum operating temperature of 550℃ and tight tolerance control (±0.05mm), they provide reliable performance in demanding environments.
