Customized Powerful Rare Earth Magnets    Neodymium Magnets China Suppliers    Neodymium Magnets China Factory

 

Rare earth magnets are very strong magnets made from alloys of rare earth elements. They are the strongest among the permanent magnets made. These magnets can be manufactured through sintering, compression bonding, injection molding, and extrusion.

 

Since their prices became competitive in the 1990s, rare earth magnets have been replacing Alnico and ferrite magnets in many applications in modern technology requiring powerful magnets. Their greater strength allows smaller and lighter magnets to be used for given applications that require high strength. The material is easily magnetized in one direction, but is able to prevent magnetic pull in any other direction.

 

As a professional magnets manufacturer, AH Magnet is committed to supplying neo magnets with normal and complex shapes. The normal magnet shapes are ring, block, round, disc, are, horeshoe, cylinder, sphere, etc. And, the most suitable magnets should be prpduced according to customers designs, click to learn about custom rare earth magnets.

 

PRODUCT DESCRIPTION

 

Materials

Rare earth permanent magnet, Ferrite, Samarium cobalt magnet

 

About this Item

Although NdFeB magnet is a kind of hard and brittle material, we can customize some complex shapes according to customers requirements. We have produced some complex shapes such as different heads, convex, concave, slotted, side punched, cut corners, non-semi-circular and countersunk magnet.

 

Different fixtures are needed when make complex samples and mass production. However, we always waive the cost of fixtures once the minimum order are USD100.

 

We do not set MOQ, maybe 1-5 pieces are also feasible, because the order amount is more calculated based on the magnetic properties and the difficulty of production.

 

What are the Different Types Of Rare Earth Magnets?

There are two types of rare earth magnets, Neodymium and Samarium-Cobalt. Their shapes can include arc, block, cube, cylinder, disc, rod, sphere and many more. You can browse through our current shapes and sizes to find the right magnet for your application. If you need a custom design, we can work with you to create unique specifications for all shapes and sizes. Contact AH Magnet, an industrial rare earth magnet manufacturer, to find out how we can help provide you custom rare earth magnets.

 

What are some of the main differences between Neodymium magnets and Samarium-Cobalt magnets?

When deciding between Neodymium Magnets and Samarium-Cobalt Magnets, there are key differences to consider before you make your decision. Some of the main difference between the two types of rare earth magnets are:

 

Advantages of Each Type of Rare Earth Magnet

Neodymium magnets have the highest energy product of any material, and this type of magnet is known for its ability to be created in a  wide range of available shapes, sizes, and grades.

 

Samarium-Cobalt magnets are known for their corrosion resistance and thermal stability. These characteristics make this type of magnet ideal for applications requiring resistance to wide-ranging temperatures and environments.

 

Disadvantages of Each Type of Rare Earth Magnet

Neodymium magnets are susceptible to corrosion and often require a protective coating. AH Magnet offers protective coating in the following materials: nickel, zinc, tin, silver, gold.

 

Samarium-Cobalt magnets are known for being more expensive compared to other types of magnets because of their durability in harsh, high-temperature environments.

 

Rare Earth Magnet Shapes

AH Magnet develops rare earth magnets in different shapes and sizes depending on the application. Some of the most common shapes for rare earth magnets include:

 

Arc, Bar, Rod, Disc, Horseshoe, Channel, Block, Ring, Sphere, Cylinders, Plugs.

 

Applications of Rare Earth Magnets

Magnetic Separators, Wind Turbines, Linear actuators, Microphone assemblies, Servo motors, Tape recorders, Alternators, Pacemakers, Stepper Motor, Permanent Magnet Synchronous Motor, DC motors (automotive starters), Flow meters, Holding Assemblies, Lifting Magnets, Magnetic Fanners.

 

Caution!

Extreme caution must be taken when working with rare earth magnets. Magnets larger than a few centimeters are strong enough to cause injuries to body parts pinched between two magnets, or a magnet and a metal surface, even causing broken bones. Magnets allowed to get too close to each other can strike one another with force to chip and shatter the brittle material, and the flying chips can cause injuries.
