Alnico5 Permanent Magnet For Measuring Instrument With Axial Magnetization Direction

Product Description:

Alnico magnets are a type of permanent magnet composed of an alloy consisting of aluminum, nickel, and cobalt. Alnico magnets are characterized by their high common magnetic properties, high temperature stability, and moderate coercive force. Cast Alnico magnets are formed through a process of melting and pouring the alloy into a mold to form the desired shape. Alnico magnets are often used in generators, microphones, and measuring instruments. The magnetization direction of Alnico magnets can be axial, radial, or multi-poles, and they can be produced in a variety of grades. Alnico 5 and 8 are the most commonly used grades. Furthermore, Alnico magnets are known for their excellent tolerance of ±0.05mm. Alnico magnets are highly valued for their strength, high temperature resistance, and stability. In conclusion, Alnico magnets offer a wide range of properties and can be used in a variety of applications.
