Casting and sintered manufacture are the two distinct procedures used to make AlNiCo. Sintered AlNiCo is often limited to smaller sizes while Cast AlNiCo can be manufactured in a wide variety of sizes and shapes. However, both procedures result in intricate arrangements and geometries. Due to its processing, standard sintered AlNiCo has tighter dimensional tolerances. Additionally, compared to Cast AlNiCo products, it has somewhat superior mechanical strength but slightly worse magnetic characteristics.
AlNiCo ring magnets are a particular kind of permanent magnet that are mostly composed of an alloy of aluminum, nickel, cobalt, and iron. To increase intrinsic coercivity, the mixture is also supplemented with copper, titanium, and niobium. AlNiCo magnets are recognized for their outstanding temperature stability and corrosion resistance. The loudspeaker, infrared guided missile, and speedometer magnets are some of the most typical uses of AlNiCo ring magnets in SDM Magnetics.
Low coercive force is a property of alnico. This indicates that external demagnetizing fields can quickly demagnetize it. So long as the tools to magnetize are available, it is therefore possible to magnetize the magnet when it is a member of an assembly. Alnico has the potential to self-demagnetize. This depends on the overall magnetic circuit, but an illustration may be taking an Alnico magnet out of a motor assembly for inspection, putting it back, and finding that the magnetic output has decreased. The Alnico magnet may self-demagnetize if the circuit is left open (self-demagnetization occurs when the working point is moved past the Intrinsic curve's 'knee'). If the magnetic circuit changes, the working point is altered. All magnets in free space produce a self-demagnetizing field, but only magnets with extremely low working points and/or low Hci values will exhibit demagnetization as a result of it. Self demagnetization occurs because the magnetic field from the magnet can pass back through the magnet itself (the magnetic path is preferable to the air surrounding the magnet), which is therefore an external demagnetizing field applied by the magnet itself.
Advantages
- High magnetic strength (although rare earth magnets offer the perfect alternative)
- They are easy to magnetize
- Offer superior corrosion resistance
- These magnets can withstand extremely high temperatures as high as 555 °C
- During the manufacturing process, the tooling cost is low
On the other hand, even if you choose alnico permanent magnets, it is worth noting that they are:
- Susceptible to demagnetization due to low coercivity
- Brittle in nature hence, cold working is not recommended during the manufacturing process
- Less powerful than rare earth metals
- Fluctuating prices of cobalt and nickel, the prices tend to fluctuate
