Product Description

NdFeb rod magnets are basically elongated NdFeB round rods. They can be used in many sensing and clamping applications. These magnets have high “Gauss” values because of their greater magnetic length and deep depth of field, making them ideal for activating Hall-effect sensors in reed switches, security, and counting applications.

Features

NdFeb Rod Magnets are made of neodymium, iron and boron and are the strongest green magnets. It’s sturdy and convenient, small and elegant. We can produce NdFeB bar magnets in different sizes, different grades (strength and temperature grades), different coatings/surface treatments, and axial and radial magnetization.

Characteristics of NdFeB Rod Magnets

NdFeB rod magnets have several distinct characteristics that make them a popular choice among manufacturers.

1. High Magnetic Strength

NdFeB rod magnets are known for their high magnetic strength. They are the strongest type of magnet commercially available. The magnetic strength of a magnet is measured in units of Tesla (T). NdFeB rod magnets can have a magnetic strength of up to 1.4 T.

2. Small Size

Despite their high magnetic strength, NdFeB rod magnets are small in size. This makes them an ideal choice for applications where space is limited.

3. Corrosion Resistant

NdFeB rod magnets are made with a protective coating that makes them corrosion-resistant. This coating helps to prevent the magnet from rusting or corroding, which can lead to a decrease in magnetic strength over time.

Advantages of NdFeB Rod Magnets

1. High Magnetic Strength

The high magnetic strength of NdFeB rod magnets makes them an ideal choice for applications where a strong magnetic force is required.

2. Small Size

The small size of NdFeB rod magnets makes them an ideal choice for applications where space is limited.

3. Corrosion Resistant

The protective coating on NdFeB rod magnets makes them corrosion-resistant, which helps to extend the lifespan of the magnet and prevent a decrease in magnetic strength over time.

NdFeB rod magnets are one of the strongest commercially available magnets. They have a high magnetic strength, small size, and are corrosion-resistant. These characteristics make them an ideal choice for many applications, including electric motors, consumer electronics, and medical devices.

Surface Treatment of NdFeB magnet 

NdFeB magnets are susceptible to corrosion, so it is necessary to give surface treatment Currently, the surface treatments mainly includes chemical plating, conversion coating and coating. In most cases, NdFeB magnet surface are treated with NiCuNi (Nickel-Copper-Nickel) plating, Zinc plating and Epoxy coating. For special requirements, passivation and phosphatization are also adopted.

FAQ

What are neodymium rod magnets?

Neodymium rod magnets are strong permanent magnets made from an alloy of neodymium, iron, and boron, shaped into a cylindrical form. They belong to the rare-earth magnet category and are known for having the highest magnetic properties of all permanent magnets available today.

How strong are neodymium rod magnets?

The strength of neodymium rod magnets varies depending on their size and grade. They can range from grades N35 up to N52 and beyond, with N52 being among the strongest. The strength is measured in terms of magnetic field density and magnetic pull force, with these magnets capable of supporting thousands of times their own weight under ideal conditions.

What applications use neodymium rod magnets?

Neodymium rod magnets are used in a wide array of applications, including electronics (such as hard drives and headphones), medical devices (like MRI machines), motors and generators, jewelry clasps, and various holding and lifting devices. Their strong magnetic fields make them ideal for applications requiring compact yet powerful magnets.

Can neodymium rod magnets be customized?

Yes, neodymium rod magnets can be customized in terms of size, grade, and magnetic orientation to suit specific applications. Custom coatings can also be applied to protect against corrosion or to meet specific environmental conditions.

How do you handle neodymium rod magnets safely?

Handling neodymium rod magnets requires caution due to their strong magnetic pull, which can cause them to snap together unexpectedly. It’s important to wear protective gloves to prevent pinching and to keep the magnets away from electronic devices and magnetic media, as their strong fields can cause damage or data loss.

Are neodymium rod magnets coated?

Yes, to prevent corrosion, neodymium rod magnets are typically coated. Common coatings include nickel, zinc, and epoxy. These coatings not only protect the magnet from corrosion but also can provide a smoother finish, which can be beneficial in certain applications.

Can neodymium rod magnets be used outdoors?

While neodymium rod magnets can be used outdoors, their resistance to environmental conditions depends on the type of coating. Epoxy coatings offer better protection against moisture and corrosion, making them more suitable for outdoor use compared to other coatings like nickel.

How do neodymium rod magnets affect electronic devices?

Neodymium rod magnets can interfere with or damage electronic devices and magnetic storage media due to their strong magnetic fields. It’s advised to keep them at a safe distance from such devices to prevent any potential damage.

Do neodymium rod magnets lose their magnetism over time?

Under normal conditions and temperatures, neodymium rod magnets maintain their magnetism for decades. However, exposure to high temperatures, strong external magnetic fields, or physical damage can reduce their magnetic performance.

How are neodymium rod magnets manufactured?

The manufacturing process involves melting the raw materials, casting, pulverizing the alloy into a fine powder, pressing the powder in a magnetic field to align the particles, sintering to fuse the particles together, and then machining the material into a cylinder shape. The final step is applying a protective coating to the magnet.
