High Temperature Resistance alnico magnets
General Description:
1, Alnico magnet material is made by alloying aluminum, nickel and
cobalt with iron.
2, Some grades also contain copper and/or titanium. The alloying
process is casting or sintering.
3, These constituents, the process and the heat treatment needed to
optimize magnetic properties produces hard (Rc45) and brittle parts
that are best shaped or finished by abrasive grinding.
4, Sintered Alnico magnet, which are also alumium-nickel-cobalt
iron alloys, is usually restricted to smaller sizes. it has
slightly lower magnetic properties, but better mechanical strength
than cast alnico magnet.
5, Sintered Alnico magnet is widely used in all kinds of sensors,
meters, controller speedometer and other applications.
6, Sintered alnico magnets have slightly lower magnetic properties,
however they have excellent mechanical properties.
7, Alnico magnets are excellent choices for applications involving
vibration and shock as they have good resistance to
demagnetization.
Typical applications for Alnico magnet
