Custom NdFeB Powerful Magnet

Custom NdFeB Powerful Magnet

1. The magnet belongs to the NdFeB rare earth permanent magnet, which belongs to the powerful magnet. It is the magnet with the highest commercial performance. The best and strongest magnetic material is the well-deserved magnetism. Because of its excellent magnetic properties, it is called "Magnetic King, please rest assured to buy, use with care.

Second, the specifications of our company are round, square, circular, shaped, trapezoidal, tile-shaped, spherical, irregular graphics and other neodymium iron boron magnets, can be customized to produce. The magnet size units for all our specifications are in millimeters.

[1] The circular size generally uses D to indicate the diameter (because it is a special symbol for most people to use D instead of Φ), for example, D10X1MM represents a magnet with a diameter of 10 mm and a thickness of 1 mm. X This is the mathematical symbol "multiply sign".

[2] The size of the square is the length X width X height. Generally, the square is represented by F. For example, F50x25x13MM means that the square magnet is 50 mm long, 25 mm wide and 13 mm thick. The default last digit is the magnetization direction of the square magnet, such as the F50x25x13 square, and the magnetization direction is 13MM. That is, the height direction is magnetized. NS is on the two largest faces, which are 50x25 faces.

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

[4] Spherical magnets are represented by a simple diameter D. For example, D5MM represents a magnetic ball with a diameter of 5 mm.

Third, our company can produce a variety of grades of NdFeB magnets, 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

33, 35, 38, 40, etc. indicate 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 material is about 40MGOe. The conversion of 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 grade, the stronger the magnetic, and the higher the price, so the specific needs should be determined according to the actual needs of the customer. Under normal circumstances, such as packaging, machinery, stationery and other products with low requirements are mainly selected n33 brand. Most of the low-end horn magnets use the n35 grade.

The sintered NdFeB magnet has an unimaginable super-strong magnetic force. The theoretical maximum suction of the sintered NdFeB magnet is hundreds of times its own weight, which is the most powerful permanent magnet at present. Of course, the larger the size of the magnet, the stronger the magnetic force.
