Products Introduction:
The magnetic alloy, "alnico," is an acronym of aluminum, nickel and cobalt, the three main elements in this mid-grade permanent magnet. Some characteristics of alnico are that it is hard, brittle, has a low coercive force, excellent temperature stability, high residual induction and fairly high energies.
Alnico magnets, in addition to their composition of aluminum, nickel and cobalt, can also be alloyed with iron, copper and often titanium in order to create a magnet with a stronger magnetic force than all other permanent magnets (with the exception of the rare earth elements of neodymium and samarium-cobalt).
More cost-effective than high-strength rare earth magnets and having higher magnetic force and permanence than ceramic magnets, alnico magnets are the perfect fit for a wide range of applications. For instance, cow magnets are made exclusively from alnico, and alnico magnets are also used in sound amplification, electric motors, sensors and many sorting and lifting tools.
In addition to these applications, alnico magnets are utilized in industries including instrumentation, research and music for electric guitar pickups, loudspeakers, traveling wave tubes and many others.
Alnico magnets are similar to ferrite ceramic magnets but are less brittle, more easily fabricated into shapes, and have higher magnetic resistance. Being a metallic magnet rather than ceramic, they do not need always to be nickel-coated for structural applications like ceramic magnets do.
Advantages
Alnico magnets are very resistant to temperatures up to 525°C and retain their magnetic properties up to high temperatures.
Alnico magnets have a high resistance to acids and other chemicals.
Alnico magnets have a high residual induction.
Alnico magnets are insensitive to corrosion.
When sintering and melting, Alnico magnets can also be manufactured in very complex ways.
Application:
Speedometer, Magnetic Separators, Magnetos, Magnetic Sensors, Electron tubes, Traveling wave tubes, Radar, Holding magnets, Receiver, Clutches and bearings, Motors, Relays, Controls, Generators, Telephones, Microphones, Loudspeakers, Bell ringers, Security systems, Cow magnets.
