Alnico Bar Magnets FAQs.

What are Alnico bar magnets made of?

Alnico bar magnets are made from an alloy of Aluminum (Al), Nickel (Ni), Cobalt (Co), and often include Copper (Cu) and sometimes Titanium (Ti). The specific composition can vary depending on the desired magnetic and physical properties.

Why are Alnico bar magnets preferred in certain applications?

Alnico bar magnets are preferred for their excellent thermal stability, high temperature resistance (up to 540°C or 1000°F), and resistance to corrosion. These properties make them ideal for applications in electric motors, sensors, and musical instruments like guitar pickups, where performance in varying environmental conditions is crucial.

Can Alnico bar magnets lose their magnetism?

While Alnico magnets have good resistance to demagnetization, they can lose their magnetism if exposed to strong demagnetizing fields or heated above their maximum operating temperature. However, under normal conditions, they maintain their magnetism over long periods.

How are Alnico bar magnets magnetized?

Alnico bar magnets are usually magnetized after manufacturing due to their high coercivity. This process requires a strong direct current (DC) magnetic field, which aligns the magnetic domains in the alloy to produce a permanent magnet.

Are Alnico bar magnets strong compared to other types of magnets?

Alnico magnets have strong magnetic fields but are generally not as strong as rare-earth magnets like neodymium. However, their strength is sufficient for many applications, especially where high temperature stability is required.

How do I identify the poles of an Alnico bar magnet?

The poles of an Alnico bar magnet are located at the two ends of the bar. If the poles are not marked, you can use a compass or another magnet to identify them: opposite poles will attract, while the same poles will repel each other.

Can Alnico bar magnets be remagnetized?

Yes, if an Alnico magnet loses its magnetism or needs to be reoriented, it can be remagnetized using a strong magnetic field. This process should ideally be done by professionals to ensure the magnet is restored to its full magnetic potential.

Cast of our AlNiCo Magnets

Cast AlNiCo magnets are produced by pouring a molten alloy of the composite metals into a mold and then further processing it through various heat-treat cycles. The resulting magnet has a dark gray exterior and may have a rough surface. Further treatment, such as machining (grinding), can be used to smoothen the surface of the magnets produced. Cast AlNiCo magnets are the most commonly used method for manufacturing AlNiCo magnets. This process produces magnets with better magnetic properties than the sintering method, but it costs more. Another thing to note about cast AlNiCo is that they are orientated and anisotropic. This means that the magnet can only be magnetized in one direction, meaning that it has an improved magnetic strength. Note also that some types of cast AlNiCo are isotropic, which means that they can be magnetized in any direction.

AlNiCo Channel Bar Magnet

An Alnico channel bar magnet is a specialized form of Alnico magnet designed for specific applications where a directed magnetic field is needed. These magnets consist of an Alnico alloy magnet encased in a steel or iron channel, which helps to focus the magnetic field on one side of the assembly, enhancing its magnetic strength in that area.

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 work Alnico channel bar magnets?

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.

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.

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.

Are Alnico channel bar magnets affected by temperature?

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 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.

Protecting Cattle from Hardware Disease

In farming, keeping cattle healthy is crucial for productivity. Hardware disease can affect up to 10% of cattle in some areas, leading to big problems like weight loss, lower milk production, and even death. To tackle this, many farmers use cow magnets—a simple but effective tool that helps prevent this serious issue by capturing metal objects cows might accidentally swallow.

AlNiCo Cow Magnet

An Alnico cow magnet is a specific type of magnet used primarily in the agricultural and veterinary fields to help prevent Hardware Disease in cattle. Hardware Disease is a common term for the condition caused when cows accidentally ingest metal objects while grazing, such as nails or wire, which can then become lodged in the cow’s digestive system, leading to serious health issues or even death.

What is a Cow Magnet?

A cow magnet is a cylindrical magnet designed specifically for use in cattle. These cow magnets are typically made from strong magnetic materials such as alnico (an alloy of aluminum, nickel, and cobalt) or ferrite, and they are usually about 2-3 inches long. Cow magnets are designed to be administered orally and settle in the reticulum, one of the four compartments of a cow’s stomach. Their primary function is to attract and hold any metal objects that the cow may inadvertently ingest while grazing.
