Click this image to zoom it.

Move the mouse over the image to zoom

A rare-earth magnet with the highest magnetic energy among the existing magnets.
[Features]
· Circular type magnet
· Not much cracking or chipping and high mechanical strength magnet
· It is cheaper than a samarium magnet, which is the same rare earth magnet.
· Due to its low temperature characteristics, the usage conditions for standard products allow use below 80°C.
· If it is a heat resistant type with improved coercivity, it can be used in high temperature ranges up to about 220°C.
· All products are surface-treated with nickel plating, etc., to be rust-resistant.
[Applications]
· Can be widely used for motors, iron powder removal, sensors, medical equipment, etc.
· Ideal for prototyping in small lots, etc.

(i)Caution

The product images are representative only. Specifications may vary by part number, including shape and color.
Due to export restrictions on rare earths in China, orders will be suspended once current stock runs out. Please note that even for large quantity quotations, delivery times may remain undetermined.

Product Feature Details

Neodymium magnets are shaped and sintered products whose main components are neodymium, iron and boron.
The exceptional magnetic energy is the highest among the existing magnets.

Magnetization Direction: Y-direction

Magnetization Direction: Radial Magnetization

Magnetization Direction: Four Poles on Both Sides

Cautions and Prohibitions

There is a risk of injury, such as fingers getting pinched, if the magnet adheres to each other, tools, or iron pieces.
If the magnets are accidentally attracted, fix one magnet and move the other to the side. This method makes it relatively easy to remove.
At this time, if tools are used, the magnet may be cracked or chipped.
Magnets are generally fragile, and neodymium magnets tend to corrode from the damaged surface.
Also, there is a risk of injury from these fragments.
Keep magnets out of reach of children. If you accidentally swallow a magnet, contact your doctor immediately.
People with metal allergies may experience itching or redness if they come into contact with magnets.
If you experience any of these symptoms, do not touch the magnet.
If the magnet comes into direct contact with water, its components may leach out. Never drink this water.
Bringing a magnet close to a credit card, cash card, etc., may render it unusable.
Bringing magnets close to precision equipment such as computers, smartphones, watches, etc., may cause malfunction.
Placing a magnet close to an electronic medical device such as a cardiac pacemaker may impair its normal operation.
Demagnetization may occur if the magnet is used outside the operating temperature range.
Applying a strong impact to the magnet or processing it may demagnetize it.
Excessive bending of rubber magnets with a thickness of 2 mm or more may cause cracks.
