the size of the ring is denoted by the outer diameter DX and the inner diameter DX height. For example, D32XD18X6 ring magnet, denotes the outer diameter of 32 mm, the inner diameter of 18 mm, and the 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 a straight hole is punched in vertically, while the countersunk hole is divided into a large hole and a small hole.

spherical magnet, expressed simply as D diameter. For example, the D5MM represents a magnetic sphere with a diameter of 5 mm.
Our company can produce ndfeb magnet of various brands as follows:
The maximum operating temperature of N35 N38 N40 N42 N45 N48 N50 N52 is 80 degrees
The maximum operating temperature of 50M is 100 degrees
The maximum operating temperature of 33H 35H 38H 40H 42H 45H 48H is 120 degrees
The maximum operating temperature of 30SH 33SH 35SH 38SH 40SH 42SH is 150 degrees
The maximum operating temperature of 30UH 33UH 35UH 38UH 40UH is 180 degrees
The maximum operating temperature of 30EH 33EH 35EH 38EH is 200 degrees
Maximum operating temperature of 30AH 33AH 35AH 230
33, 35, 38, 40, etc. represent the maximum magnetic energy product. The maximum magnetic energy of N33 ndfeb material is about 33MGOe and N35 ndfeb material is about 35MGOe. The maximum magnetic energy product of the N40 material is about 40MGOe. The conversion between MGOe and kA/m3 is 1MGOe = 8kA/m3, which means the maximum magnetic energy product of N40 is about 320kA/m3. The higher the brand number, the stronger the magnetism, the higher the corresponding price, so specific needs to be determined according to the actual needs of customers. In general, such as packaging, machinery, stationery and other less demanding products are mainly n33 brand. Most of the low - and medium-grade loudspeakers use n35 brand magnets.
