Horseshoe Magnets

Horseshoe Magnets in Alnico (AINiCo)

Our Horseshoe magnets are predominantly used in classroom settings as they are great for teaching children how magnetic fields operate and the difference between the north and south poles. The horseshoe magnet is universally recognized as a symbol for magnets and magnetism. The design allows for two separate poles to clearly display the difference between the north and south pole and the attract/repel reactions when exposed to another magnet.

Horseshoe magnets are created from Alnico, an extremely heat resistant magnetic material, able to withstand very high temperatures without losing its magnetic integrity. Their name and their make-up are derived from aluminum, nickel and cobalt! They have an incredible resistance to corrosion and although they are the weakest of the permanent magnets (in comparison to Neodymium and Ferrite magnets), they are physically more durable and are not nearly as brittle as the others. For your reference, the dimensions for our Horseshoe Magnets are Height (mm) x Width (mm) x Depth (mm).

ALNICO POWER MAGNETS

The Alnico horseshoe magnet is a classic Alnico magnet shape. Sometimes the Alnico horseshoe magnet is called a C-shape magnet and is also known as a pocket Alnico horseshoe magnet, a minor Alnico horseshoe magnet, and a power Alnico horseshoe magnet - they are all Alnico horseshoe magnets but have different sizes and performances.

The Alnico horseshoe magnets are capable of operating at temperatures of up to a maximum of +550 degrees C. The Alnico horseshoe magnets are supplied in natural (uncoated / unpainted) and red paint finishes. The Alnico horseshoe magnets can be offered in other dimensions and grades.

Horseshoe Magnets are regarded as the most quintessential magnet available and are recognised as the universal symbol for magnets and magnetism. Our handy horseshoe magnets are strong and versatile. They have a maximum operating temperature of 500⁰C. These magnets are perfect for teaching environments when learning about magnetism and the north and south magnetic properties, since both ends are clearly labelled as such. The north and south poles are always shown in different colours or stamped white on a red background. The material composition is normally Alnico although sometimes horseshoe magnets are made of ferrite material.

When we think about magnets, many people will think about the horseshoe magnet. The image of these magnets has been planted in our brands ever since first learning about them in science experiments at school! We have a wide range available with pull strengths up to 47kg.

Alnico

As one of the members of magnets family, Alnico remains the workhorse of the permanent magnet industry and can be relied upon to deliver impressive flux density at an economical price. Excellent temperature stability, high residual induction, and relatively high energies characterize Alnico materials, composed primarily of alloy of Aluminum, Nickel, and Cobalt. They are manufactured through either a casting or sintering process. Cast magnets may be manufactured in complex shaped, such as horseshoe.

More About Alnico Magnets

Alnico magnets are composed of aluminum, nickel and cobalt. They offer a very strong magnetic field, second only to rare earth magnets, and are commonly available in horseshoe, cylinder, or rod shapes.
The benefits of this unique material include:

• Flexibility in selecting the shape due to casting process
• Can be magnetized in one or all directions
• High energy
• Surface protection coating not required
• Temperature stability

Ideal for High Temperature Applications

Alnico is an extremely hard material that performs well in high temperature situations, offering a service limit of 550 degrees Celsius. 

Types of Alnico Magnets

On the basis of manufacturing process and application alnico can be grouped into following types:

• Cast Alnico
• Sintered Alnico
• Bar Alnico

Alnico magnets can be fabricated into many shapes and types:

• Alnico horseshoe magnets
• AlNiCo rod magnets uncoated

Features

• Alnico's are the strong magnets which can produce strong magnetic fields.
• Excellent resistance to corrosion
• They have superior thermal stability
• These magnets have some of the highest curie points of any magnetic material ranging around 800oC
• Some type of Alnico's are isotropic
• They have high magnetic flux density

Applications

Alnico magnets have applications in the following areas:

• Electric motors
• Electric guitar pickups
• Sensors
• Loudspeakers
• Cow magnets
• Automotive and electronic sensors
• Actuators
• Hall effect sensors
• Magnetron
• Reed switches
• TWT aomplifiers
• Communication

Manufacturing Process

Casting or sintering process is applied for making alnico magnets. The first step involves the pouring of molten metal alloys into moulds. Later it is passed through various heat cycles. The resultant magnets have rough surface which after machining gives a glossy look. Sintered magnets are produced by compacting fine alnico powder in a press, and then sintering the compacted powder into a solid magnet. Alnico magnets can only be magnetized only in the field having magnetizing fields of about 3 kOe. Since these magnets have low coercivity they, must be protected from the adverse repelling fields as this could partially demagnetize the magnets.

Magnetizing

After the tolerance magnetizing is effected. As alnico magnets are brittle, they must be protected from hard blows and handled with care. It should be magnetized in a proper magnetic field and must be prevented from the repelling fields as it is prone to demagnetization.
