Alnico Magnets possess a hard and brittle nature, making them prone to chipping and cracking. To machine this material, specialized machining techniques are necessary. Magnetizing fields of approximately 3kOe (kilo Oersted) are required for Alnico magnets. Due to their relatively low coercivities, precautions must be taken to avoid adverse repelling fields that could result in partial demagnetization. It is advisable to store magnetized magnets with "keepers" to minimize the risk of partial demagnetization. In case of partial demagnetization, Alnico magnets can be easily re-magnetized. Cast Alnico allows for the creation of intricate and complex shapes, which is not feasible with other magnetic materials. An example of this is an Alnico rotor with a protected steel sleeve and epoxy potting. Alnico magnets are primarily composed of aluminum, nickel, cobalt, copper, iron, and sometimes titanium. Among the range of magnetic materials available, Alnico magnets exhibit high magnetic flux density, corrosion resistance, and excellent temperature stability, with a maximum working temperature of 600℃. Alnico magnets find wide applications in sensors, meters, electronics, instruments, medical devices, educational tools, automotive, aviation, and various other fields.
The magnetic cores of deep pot magnets are made of neodymium (NdFeB), samarium-cobalt (SmCo), or Alnico (AlNiCo), which is an alloy of aluminum, iron, copper, nickel, and cobalt. The choice of material affects the adhesive force and temperature resistance of the magnets.
Neodymium magnets are known for their exceptional strength.
Alnico magnets have a good adhesive force but cannot match the strength of neodymium pot magnets.
Samarium cobalt systems fall in between these two magnet systems in terms of their power development.
However, when it comes to temperature resistance, the situation is reversed. Alnico systems can endure the highest levels of heat, while neodymium systems generate the least amount of heat.
The magnets have the following maximum operating temperatures:
NdFeB 80°C / SmCo 250°C / AlNiCo 450°C.
