Alnico Magnets

Strong Magnetic Field, High Energy, Corrosion Resistant Alnico Magnets for Industrial Applications

Jobmaster Magnets’ alnico magnets are a great answer for you.  Alnico ferromagnetic alloys have the ability to produce a very strong magnetic field, which is why alnico magnets are known for their strength.  In fact, only rare earth magnets are stronger.  Composed primarily of aluminum, nickel and cobalt, hence al-ni-co, alnico magnets are produced either through a casting or sintering processes.  Sintering produces better mechanical abilities in the magnet.  Cast alnico’s, however, may be manufactured in unique and intricate shapes. This gives you more freedom regarding the nature and utilization of your magnet, which is not always possible with other magnetic materials.  Through casting or sintering, the metal is magnetized as either anisotropic or isotropic.  Anisotropic alnico magnets have a preferred direction of magnetization, whereas isotropic magnets are magnetized in all directions. 

Other positive attributes of Jobmaster Magnet’s Alnico magnets include:

• high energy
• strong corrosion resistance
• high residual induction
• first-rate temperature stability
• no coating needed for surface protection
• working temperatures can be as high as 450-5500 C

How Are Alnico magnets currently being applied and valued in real life?

Their strength and permanency makes them highly valuable for industrial and consumer applications that require stable temperature properties.  Alnico magnets are considered highly valuable in fields like aviation, military technology and space flights for this reason.

Other applications include:

• electric guitar pickups
• microphones
• electric motors and ignition systems
• generators
• hand tools
• sensors
• loudspeakers
• car lighters and odometers
