alnico
Aluminum nickel cobalt permanent magnet is an alloy consisting of metal, aluminum, nickel, cobalt, iron and other trace metal elements. Its metal composition is different, the magnetic properties are different, so the use is also different. There are two different production processes for aluminium nickel cobalt permanent magnet: Casting and sintering. Casting aluminum nickel cobalt process can be processed into different sizes and shapes, high strength, corrosion resistance, and has good temperature stability, the maximum operating temperature of more than 600 degrees celsius. Casting aluminum nickel cobalt products are widely used, mainly used in a variety of sensors, meters, electronics, mechanical and electrical, medical, teaching, automotive, aviation, military technology and other fields.
Compared with sintered alnico products and cast alnico products, mainly small size, slightly lower than the magnetic properties of cast alnico products, but the machinability is good. Sintered aluminium nickel cobalt products are widely used in a variety of instruments, magnetic sensors, controllers, automotive ignition, odometer and other applications.
Alnico features:
1 、 compact crystallization, high strength and strong corrosion resistance
2, magnetic consistency is good, magnetic uniformity
3, good temperature stability (Br temperature coefficient is the smallest of all kinds of permanent magnetic material)
4, the highest use temperature of 600 degrees
5 sintered magnets can produce magnets of small size and complex shape and composite magnets
Aluminium nickel cobalt magnet steel concrete application:
1 、 internal magnetic voltage ammeter, electronic watt hour meter, multimeter, flowmeter and so on
2 、 all kinds of magnetic sensors, polarized relays, temperature and pressure controllers
3, the mobile phone receiver, buzzer, hearing aids, mini speaker
4 、 automobile ignition starter, automobile and motorcycle odometer, permanent magnet motor, adsorption device, etc.
5 、 widely used in aviation, aerospace, military equipment and other fields requiring high stability
