High Quality 12 mm x 15 mm alnico rod magnet
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.
Application:
1.Inner magnetic voltmeter/ammeter, electronic type power energy measuring instrument, avometer, flow meter
2.A wide range of magnetic sensor, polarized relay, temperature and pressure controller
3.Buzzer of mobile phone, hearing aids, mini speaker
4.Lighter of automobile, odometer of automobile and motorcycle, permanent magnet motor, absorptive appliance
5.Widely applied in high stability fields, such as aviation, spaceflight and military technology.
Application of Cast AlNiCo Magnets:
Separators,Sensors,Electron tubes,Traveling wave tubes,Radar,Holding magnets,Clutches andbearings,Motors,Relays,Controls,Generators,Receivers,Telephones,Microphones
Bell ringers,Loudspeakers,Cow magnets,Educational products
