Precautions during the use of the magnet:

 

1. Temperature
Customers should choose their own magnet brand according to their working temperature when choosing NdFeB magnet. If the working temperature is higher than the magnet brand bearing temperature, the magnet will gradually demagnetize until it is non-magnetic. Please be sure to confirm the working temperature and the brand suitable for your own use before ordering.
2. Environment
If the magnet device is used in a sealed state, you can consider choosing a magnet with no plating or white zinc plating on the surface, which can save costs. If the magnet is exposed to humid air, especially in the salt fog state, it is recommended to consider the magnet with nickel plating on the surface. Magnets should be stored in a dry and constant temperature environment, separated and wrapped with plastic, wood piece, cardboard, foam, etc. Keep away from iron and easily magnetized items, such as monitors, bank cards, computers, televisions, mobile phones, etc.
3. User objects
With regard to environmental protection, for relatively developed countries, users in North America, Europe and other places should pay special attention to environmental protection matters, and export use must pass the six EU standards of SGS. For users in China or some underdeveloped countries, environmental protection requirements are not considered.

4. Handling and stacking

Strong NdFeB magnet the material is hard, brittle, and the magnetic field is strong. It should be gently taken and placed (especially large specifications and thin sheets). When the strong magnet itself or is attracted or separated from other iron devices, it should be carefully operated without impact. Otherwise, it is easy to cause collision and damage the magnet or hurt the finger. Because NdFeB is a multi-metal alloy material with a density of 7.45, it has the characteristics of heavy and brittle. Therefore, be careful when handling and holding to avoid magnetic fragmentation. The storage environment should also be kept dry. Do not pile it directly on the ground. It is better to pad it with thick cardboard or place it on the shelf.

5. Access instructions

When the magnets can't be drawn and separated from each other, it is recommended to push them horizontally and stagger them, and do not pry them hard. Use the left hand to fix the whole magnet, and use the index finger to cooperate with the thumb on the right hand to move the magnet horizontally. After moving out, do not throw the moved magnet back to the magnet pile immediately, please isolate the magnet immediately. Take it lightly, and wrap the taken-out paper in a place far away from the iron or the magnetic thing (about 16cm) or paper, so that it is safer. If you need to put the magnet back into the whole magnet, please put it back slowly and move it in close distance from the edge. The hand must hold the magnet until the magnet has been moved in.

 

Purchase instructions:
The following items should be understood before purchasing NdFeB magnet:
1. What material and performance do you need?
 
2. Dimension and tolerance?
 
3. Do you want to magnetize? If you want to magnetize, which way is it, axial? Radial?

4. The highest temperature of the magnet working environment?

5. Order quantity?

6. Surface treatment? Galvanized, Nickel Plated?

7. The above specifications and Price pictures are for reference only, and the specific price is determined according to the actual size.

8. If the order (payment) is taken, the customer service is not contacted to confirm, and the goods will not be shipped.

 

II. The specifications produced by our company include round, square, toroidal, special-shaped, trapezoidal, tile-shaped, spherical, irregular pattern and other NdFeB strong magnets, which can be produced customization as request. All our magnet sizes are measured in millimeters.

 

[1] Circular size generally uses D to indicate the diameter (because it is a special symbol for convenience, most people use D instead of Φ at present), for example, D10X1MM indicates the diameter is 10mm, the thickness is 1mm magnet. X this is the mathematical symbol "multiplication sign".

 

[2] The square size is length x width x Height. Generally, F is used to represent the square. For example, F50x25x13MM indicates that the length of the square magnet is 50mm, the width is 25mm, and the thickness is 13mm. Generally, by default, the last number indicates the magnetization direction of the square magnet, for example, for a F50x25x13 square, the magnetization direction is 13mm, that is, the height direction is magnetized. NS is in the two largest faces, that is, 50x 25 faces.

 

[3] The size of the ring indicates the height of the outer diameter DX inner diameter DX. For example, a D32XD18X6 ring magnet indicates an outer diameter of 32mm, an inner diameter of 18mm, and a height of 6mm. Height is also called thickness. At present, the ring is also divided into straight hole and countersunk hole. The straight hole is inserted vertically, while the countersunk hole is divided into large hole and small hole, and the depth of large hole and small hole are commonly known as screw holes.

 

[4] spherical magnet, which means simple diameter D. For example, D5MM indicates magnetic ball with a diameter of 5mm.

 

3. Our company can produce NdFeB magnets of various brands, as follows:

 

N35 N38 N40 N42 N45 N48 N50 N52 maximum operating temperature 80 degrees
35m 38m 40m 42M 45m 48m 50m maximum operating temperature 100 degrees
33H 35H 38H 40H 42H 45H 48h maximum operating temperature 120 degrees
30SH 33SH 35SH 38SH 40SH 42SH maximum operating temperature 150 degrees
30UH 33UH 35UH 38UH 40UH maximum operating temperature 180 degrees
30EH 33EH 35EH 38EH maximum operating temperature 200 degrees
30AH 33AH 35AH maximum operating temperature 230 degrees

33, 35, 38, 40, 42, etc. represent the maximum magnetic energy product.

The maximum magnetic energy product of N33 NdFeB Material is about 33mgoe;

The maximum magnetic energy product of N35 NdFeB Material is about 35mgoe;

The maximum magnetic energy product of N40 NdFeB Material is about 40mgoe.

The conversion between MGOe and kA/m3 is 1MGOe = 8kA/m3, which means that the maximum magnetic energy product of N40 is about 320kA/m3.

The higher the brand, the stronger the magnetism, and the higher the corresponding price, so the specific needs should be determined according to the actual needs of customers. Under normal circumstances, products with low requirements such as packaging, machinery, stationery and so on are mainly made of n33 brand. Most of the medium and low-grade horn magnets use n35 brand.

Sintered NdFeB magnet has unimaginable Super magnetic force. Theoretically, the maximum suction force of sintered NdFeB magnet is hundreds of times its own weight, which is the most powerful permanent magnet at present. Of course, the larger the magnet size, the stronger the magnetic force.
