Product Information

The sintered AlNiCo magnets are mainly composed of aluminum (Al), nickel (Ni), and cobalt (Co), so it is al-ni-co. They also include copper and sometimes titanium. AlNiCo alloys are ferromagnetic, have high coercivity (antimagnetic loss) and can be used to make permanent magnets. Its composition is typically 8-12% aluminum, 15-26% nickel, 5-24% cobalt, up to 6% copper, up to 1% titanium, and the remainder iron.

Application

The sintered AlNiCo magnets are widely used in industrial and consumer applications where strong permanent magnets are needed, such as electric motors, electric guitar pickups, microphones, sensors, loudspeakers, magnetron tubes, and cow magnets. In many applications they are being superseded by rare earth magnets, whose stronger fields (Br) and larger energy products (BHmax) allow smaller size magnets to be used for a given application.

Magnetic Properties of Sintered Alnico Magnet

Alnico alloys make strong permanent magnets, and can be magnetized to produce strong magnetic fields. Of the more commonly available magnets, only rare-earth magnets such as neodymium and samarium-cobalt are stronger. Alnico magnets produce magnetic field strength at their poles as high as 1500 gauss (0.15 tesla), or about 3000 times the strength of Earth’s magnetic field. 

Alnico alloys have some of the highest Curie temperatures of any magnetic material, around 800 °C (1,470 °F), although the maximum working temperature is normally limited to around 538 °C (1,000 °F). They are the only magnets that have useful magnetism even when heated red-hot. This property, as well as its brittleness and high melting point, is the result of the strong tendency toward order due to intermetallic bonding between aluminium and its other constituents. They are also one of the most stable magnets if they are handled properly. Alnico magnets are electrically conductive, unlike ceramic magnets.

Production

The sintered AlNiCo magnets offer the best temperature characteristics of any standard production magnet material available. Alnico magnets can be used for continuous duty applications where temperature extremes up to 930°F (500°C) can be expected.

Introduction of Alnico magnet

     Alnico magnet is composed primarily of alloys of aluminum, nickel, cobalt, copper, iron, and sometimes titanium, which has remarkable resistance against corrosion and high temperature, and is mainly used in certain precision instruments, such as such as meters, motors and sensors.

     There are two kinds of the Alnico magnets due to different manufacturing processes: Cast Alnico and Sintered Alnico. Cast AlNiCo magnet is made by pouring melted AlNiCo into a mold. The solidified material is rough ground and then heat treated and cooled. Most AlNiCo magnets are in shapes of disc, block and ring. Casting process can be used to manufacture magnets with different shapes, the magnetic property of cast magnet is better than sintered AlNiCo magnet.

     Compared with cast alnico, the advantages of sintered alnico magnet are smaller size, tighter dimensional tolerances and better machinability, but sintered magnetic properties are slightly lower than cast alnico magnet.
