FAQ

What are Alnico channel bar magnets?

Alnico channel bar magnets are composed of an Alnico magnet (made from an alloy of Aluminum, Nickel, and Cobalt, and often including Copper and sometimes Titanium) seated within a metal channel. This channel acts to direct the magnet's field, increasing its strength on the open side of the channel.

How do Alnico channel bar magnets work?

The steel or iron channel surrounding the Alnico magnet serves to guide the magnetic field so that it is concentrated on one side of the magnet. This configuration allows for a stronger magnetic pull from the open side, as the channel effectively shields the other sides, minimizing magnetic dispersion.

What are the advantages of Alnico channel bar magnets?

Directed Magnetic Field: The channel directs the magnetic field to where it is needed most, increasing efficiency in applications. High Temperature Resistance: Like all Alnico magnets, channel bar magnets can operate in high temperatures up to 540°C (1000°F). Corrosion Resistance: Alnico's inherent corrosion resistance is complemented by the protective channel, offering durable performance in harsh environments. Versatility: These magnets can be used in various applications, including holding, lifting, and closure mechanisms where directed magnetic force is beneficial.

What applications are Alnico channel bar magnets used for?

They are commonly used in applications requiring a focused magnetic field for holding or clamping purposes, such as in: Workholding devices Door and cabinet closures Educational tools for demonstrating magnetic principles Latching mechanisms

How are they different from other Alnico magnets?

The key difference lies in the metal channel that houses the Alnico magnet. This design focuses the magnetic field on one side, providing a stronger, more directed magnetic force compared to standard Alnico bar or button magnets that emit a magnetic field more uniformly in all directions.

Can Alnico channel bar magnets be customized?

Yes, like other Alnico magnets, channel bar magnets can be customized in terms of size, shape, and magnetic orientation to suit specific applications. However, customization options may be limited by manufacturing processes and the physical properties of the Alnico material.

How do you care for and maintain Alnico channel bar magnets?

Handling: They should be handled with care to avoid impact or pressure that could chip or break the brittle Alnico magnet. Storage: Store in a dry, mild environment to prevent corrosion of the channel, although Alnico itself is corrosion-resistant. Using keepers or storing in pairs can help maintain their magnetism over time.

Can the magnetic strength of an Alnico channel bar magnet be increased?

The magnetic strength is primarily determined by the alloy composition and the manufacturing process. While the channel design inherently increases the effective magnetic force on one side, further enhancements would involve optimizing the magnet's size, shape, and alloy composition.

Are Alnico channel bar magnets affected by temperature?

Alnico magnets have excellent temperature stability, retaining their magnetism in temperatures up to 540°C (1000°F). However, like all magnets, their magnetic strength can slightly decrease when heated and typically returns to normal once the magnet cools down to room temperature.
