alnico magnet

AlNiCo magnets, are made up of a composite of aluminum, nickel and cobalt with small amounts of other elements, have good temperature stability, good resistance to demagnetization, high residual induction, and relatively high energies. By strength, they are much weaker than NdFeB magnets, SmCo magnets and Ferrite magnets.
Alnico magnets are produced by two typical methods, casting or sintering. Casting delivers higher energy products and allows for the design of intricate shapes. Sintering is usually restricted to smaller sizes and offers slightly lower magnetic properties, but has tighter dimensional tolerances due to its processing.
AlNiCo magnets can be produced with either is otropic or anisotropic properties. Alnico 5 and Alnico 8 are anisotropic and exhibit a preferred direction of orientation, Magnetic orientation should be specified on your drawing when you send an order to us. Cast Alnico 5 is the most commonly used of all the cast Alnico's. It combines high indications with a high energy product of 5 MGOe or more and is used extensively in rotation machinery, communications, meters and instruments, sensing devices and holding applications.
