Our neodymium ring magnets are made of the strongest magnetic material available, offering exceptional strength and durability for a wide range of applications. From motors and generators to magnetic jewelry and advanced scientific equipment, neo ring magnets are an essential component in numerous industrial and consumer products.
Strong Neo Ring magnets are the strongest commercially produced rare earth ring magnets.
Rare earth neodymium ring magnets are hard and brittle and may chip or break if dropped.
Strong Neo magnets rings are usually magnetized through the thickness.
Uncoated neodymium ring magnets are not rustproof and may corrode in humid conditions.
Operating temperatures of neodymium ring magnets vary among material grades.
Strong Neo ring magnets can be assembled by using strong adhesives. Make sure that all contact surfaces are clean and dry prior to bonding.

Neodymium ring magnets are made using a process known as sintering. Here's how the process works:
1. Powders:
The first step is to obtain the materials needed to make the magnet. This typically involves obtaining neodymium, iron, and boron powders as well as other materials such as dysprosium, copper, or aluminum. These powders need to be carefully weighed and mixed to produce a consistent mixture.
2. Pressing:
Once the powders are mixed, they are pressed into a ring-shaped mold at high pressure. This helps to compress the powder and improve the magnetic properties of the final magnet.
3. Sintering:
The compressed powder is then heated to a high temperature of around 1,000°C or higher in a furnace. This causes the individual particles in the powder to bond together to form a solid ring. The ring is then slowly cooled down to room temperature, which helps to further strengthen the magnet.
4. Cutting and Grinding:
After sintering, the rings are cut and ground to the required shape and size.
5. Coating:
Finally, neodymium ring magnets are typically coated with a protective layer to prevent them from corroding. Different coatings may be used depending on the application.
Overall, the process of making neodymium ring magnets is complex and requires a high degree of precision and expertise. However, the end product is a powerful and reliable magnet that can be used in a wide range of applications.

1. Countersunk Neodymium Ring Magnets:
These magnets have a countersunk hole in the center, making them ideal for attaching to components using screws or bolts.
2. Radial Neodymium Ring Magnets:
These magnets have the poles on the flat faces and the magnetic field perpendicular to the ring direction, making them ideal for use in sensors, meters, and other applications requiring a radial magnetic field.
3. Axial Neodymium Ring Magnets:
These magnets have the poles on the curved surfaces and the magnetic field aligned along the ring direction, making them ideal for use in motors and other applications requiring a high torque.
4. Halbach Neodymium Ring Magnets:
These magnets use a special geometry to create a stronger magnetic field on one side of the ring and a weaker field on the other, making them ideal for use in high-performance applications such as particle accelerators and magnetic levitation systems.
5. Segmental Neodymium Ring Magnets:
These magnets are made by cutting a neodymium ring magnet in the shape of a pizza slice, which allows for more precise control of the magnetic field and can be used in applications such as MRI machines and linear motors.
6. Multi-Pole Neodymium Ring Magnets:
These magnets use a special design to create multiple poles around the ring, which can increase the magnetic field strength and allow for more precise control of the field, making them ideal for use in high-performance robotics and other applications that require strong and precise magnetic fields.
Rare earth ring magnets are usually known as strong type ring magnet, and strongest and most powerful ring magnet for the same size must be made of rare earth neodymium.
Like as other ring magnet, a ring shaped neodymium magnets are expressed with out-diameter,inner diameter and thickness, for example: OD x ID x H(T)
