AlNiCo Horseshoe Magnet Description

The Alnico horseshoe magnet is composed of aluminum-nickel-cobalt with excellent temperature stability and high residual inductance. Alnico magnets include metal keepers to help retain magnetic power.

AlNiCo Horseshoe Magnet Application

AlNiCo Horseshoe Magnet is widely used in teaching and playing. Hard Ferrite or Cast AlNiCo will be used in the Educational magnets, due to lower cost and good property. Many shapes, sizes, and colors are available for clients’ choice.

Stanford Magnets specializes in manufacturing and supplying AlNiCo horseshoe magnets applied in various industrial applications. We have advanced technology, rich experience, and professional engineering technicians in this field. If you require a specific size, please contact us for a quote.


What are the key features of Alnico horseshoe magnets?
High Temperature Resistance: Alnico magnets can withstand high temperatures up to 540°C (1000°F), making them ideal for applications in high-temperature environments. Corrosion Resistance: These magnets exhibit excellent resistance to corrosion and do not require additional protective coatings. Magnetic Stability: Alnico horseshoe magnets offer superior stability over a wide range of temperatures compared to other types of permanent magnets.
What are Alnico horseshoe magnets used for?
Alnico horseshoe magnets are used in a variety of applications, including: Educational Tools: Demonstrating magnetic principles in classroom settings. Holding and Lifting Devices: Providing a concentrated magnetic field to hold or lift metal objects. Sensors and Actuators: In applications requiring reliable performance across a broad temperature range. Magnetic Chucks and Separators: For industrial applications involving metal separation or clamping.
How strong are Alnico horseshoe magnets?
While Alnico magnets are known for their thermal stability and durability, they generally have a lower magnetic strength compared to rare-earth magnets like neodymium. However, the horseshoe design efficiently concentrates the magnetic field, enhancing the strength at the poles for effective performance in many applications.
Can Alnico horseshoe magnets be customized?
Yes, Alnico horseshoe magnets can be customized in terms of size, shape, and magnetic orientation to meet specific application requirements. The alloy composition can also be adjusted to optimize the magnet's properties for particular uses.
How do you care for Alnico horseshoe magnets?
Handling: Care should be taken to prevent chipping or breaking, as Alnico is brittle. Storage: Store away from electronic devices and magnetic media to prevent data loss or damage. Keeping magnets in pairs or with a keeper (a piece of iron that connects the poles) helps maintain their magnetic strength. Cleaning: They can be cleaned with a damp cloth if necessary; avoid using harsh chemicals.
Are Alnico horseshoe magnets affected by external magnetic fields?
Alnico magnets have a high resistance to demagnetization, meaning they are less likely to lose their magnetism when exposed to external magnetic fields compared to some other types of magnets. However, extremely strong magnetic fields can still affect them.
Can Alnico horseshoe magnets be demagnetized?
Yes, like all permanent magnets, they can be demagnetized if heated above their maximum operating temperature (Curie temperature) or exposed to a strong demagnetizing field. However, under normal circumstances and use, they maintain their magnetism well.
How are Alnico horseshoe magnets made?
They are typically manufactured through a casting or sintering process. The casting process involves pouring molten Alnico into a mold, which allows for complex shapes like the horseshoe to be created. Sintering involves pressing Alnico powder into a mold and heating it, resulting in a magnet with fine-grained microstructure and slightly different magnetic properties.
Can Alnico horseshoe magnets be remagnetized?
Yes, if demagnetized, Alnico horseshoe magnets can be remagnetized by exposing them to a strong magnetic field in the correct orientation. This process is best done by professionals with the appropriate equipment.
