* Brief Introduction to Alnico Magnets
Alnico describes a family of materials, which is comprised of aluminum, nickel, cobalt and iron with varying additions of other elements by varying the composition it is possible to tailor the magnetic properties to meet the needs of a wide variety of end use applications.
There are two different manufacturing processes for Alnico Magnets:Cast Alnico Magnets can be made into many sizes and shapes, whereas Sintered Alnico Magnets is usually restricted to smaller sizes. However,both processes lead themselves to complex geometries and configurations.
Standard Sintered Ainico Magnets has tighter dimensional tolerances due to its processing. It also has slightly lower magnetic properties, but better mechanical strength than cast Alnico products which possess the lowest reversible temperature coefficient magnetism in permanent magnet materials but have excellent working temperature.
* Attributes of Alnico Magnets
Alnico magnets are coarse and brittle and crack easily so the regular machines cannot be used to treat alnico.
They exhibit small changes in magnetic properties to temperature effects.
Maximum working temperatures can be as high as 450-870 ℃.
Have low coercive force.
Strong corrosion resistance.
No coating needed for surface protection.
