【If you need to customize, please contact us, you need to customize the type of magnet, size, brand, quantity, plating layer, tolerance requirements, magnetization direction. We will produce according to your requirement. 】

Customers in the purchase of ndfeb magnets before the following things to know:

     First, in hao magnetic steel factory sales of this category of magnets are ndfeb rare earth permanent magnet, are strong magnets, is found commercial performance of the highest magnet. The best and strongest magnetic materials are well - deserved strong magnetism. Because of its excellent magnetic properties and known as \"magneto, please rest assured that you buy, careful use.

       Ii, I produce specifications and types of circular, square, circular ring, shaped, trapezoid, tile, spherical, irregular graphics such as ndfeb strong magnet, can be customized production. All sizes of our magnets are measured in millimeters.

     【 1 】 generally expressed in D diameter circular size (due to belong to the special symbol for the convenience of the majority to use D instead of Φ), such as D10X1MM represents is 10 mm in diameter, 1 mm is the thickness of the magnet. This is the mathematical notation for X.

     [2] the size of a square is X long, X wide and X high. For example, F50x25x13MM, represents the square magnet is 50 mm long, 25 mm wide, thickness is 13 mm, generally the default last number represents the magnetization direction of the square magnet, such as F50x25x13 square, magnetization direction is 13MM direction, namely height direction magnetization. NS is on the two largest faces, which is 50x25.

     [3] the size of the ring is denoted by the outer diameter DX and the inner diameter DX height. For example, a D32XD18X6 ring magnet has 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 hole of the straight hole is vertically punched in, while the countersunk hole is divided into big hole and small hole. The depth of big hole and small hole is commonly known as screw hole.

Iii. Our company can produce a variety of ndfeb magnets, as follows:

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 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, the stronger the magnetic, the corresponding price is higher, so the specific needs according to the actual needs of customers to set. In general, such as packaging, machinery, stationery and other requirements are not high products are the main choice of n33 brand. Most of the low and medium grade horn magnets are n35.

Sintered ndfeb magnet, has an unimaginably strong magnetic force, sintered ndfeb magnet theoretical maximum suction is hundreds of times its own weight, is the most powerful permanent magnet. Of course, the larger the size of the magnet, the stronger the force.
