1. Magnetic field strength: the magnetic field strength depends on the grade and specification of the magnet. Simply think that the higher the grade, the higher the surface magnetic field, which is wrong! The premise is that under the same specifications, the higher the brand, the higher the surface magnetic field! For example, the table magnetism of N35 D3 * 10> N50 d30 * 2.

2. Suction size: the higher the Surface magnetism, the greater the suction per unit area! Suction = unit table magnetic * unit area. Therefore, we cannot simply think that the magnet with high surface magnetism must have great suction! For example, the suction force of N50 D3 * 10 is <N33 10*5 (although the surface magnetism of N50 D3 * 10 is> N33 10*5).

3. Brand grade: sintered NdFeB divides a series of brand grades according to the coercive force (determining the bearing temperature) and magnetic energy product (determining the size of unit magnetic force), as an ordinary consumer, you only need to master two elements (temperature and magnetic energy product):

  N gear maximum operating temperature 80 degrees M gear maximum operating temperature 100 degrees

  H gear maximum working temperature 120 degrees SH gear maximum working temperature 150 degrees

  UH gear maximum operating temperature 180 degrees EH gear maximum operating temperature 200 degrees

  AH gear maximum working temperature 220 degrees

As for the number before these letters, it represents the magnetic energy product, for example, 45H, which tells us that the highest working temperature of this material is 120 degrees and the magnetic energy product is 45mgsoe (Mega Gauss Oster, is a unit name).

Magnet is a cold door product. We strongly recommend that you read the product description and common sense of magnet carefully:

1. The unit of NdFeB magnet is mm (mm), so when you buy it, you should see the specific size clearly. Do not buy it only by imagination, so as not to order the wrong product.

2. NdFeB magnet is fragile, especially thin sheet and long strip. More attention should be paid to the operation. When separating the magnet, it is translated and staggered like a sliding phone. Don't break it directly and keep a certain distance after separation.

3. The surface of NdFeB has coating protection and anti-rust and anti-corrosion effect. If it is not used in time, please keep it in a dry environment.

4. NdFeB is very magnetic, so please stay away from your related electronic products, such as magnetic cards, mobile phones, watches, etc.

5. Strong magnetic should be placed in places that children cannot get in order to avoid swallowing or pinching, and magnet should not collide to avoid debris hurting people.

6, if you need to customize, please send us the drawings.
