Foreign trade export factory production ndfeb strong magnetic steel strong round square shaped magnet can be customized to fast, stable, batch production brand: N35--N45 35 h - 45 h 35VH--45 VH 35SH--45SH and other products, can produce a variety of properties of the square, tile, cylinder, ring, irregular sintered ndfeb magnetic steel products.                 

Product features:It has the characteristics of high magnetic energy product, high coercivity and high magnetic induction. At the same time, it has good stability and is not easily affected by external magnetic field vibration and impact of temperature. The surface treatment can meet the requirements of salt spray test for 24 hours, 48 hours and above 72 hours. Product specification size, performance, can be produced according to user requirements, the surface can be galvanized, nickel plating, nickel copper nickel 。                                                         

 Product order description:

If you need to order production, please provide the following information: 
1. Magnetic properties. 
2. Dimensions and tolerances. 
3. Should it be magnetized? If you want to magnetize, how? Axial? Radial? 
4. Maximum operating temperature of magnet. 
5. Quantity ordered. 
6. Surface treatment. Zinc, nickel? 
7. If there are any other special requirements, Please let us know.                                                                 Magnet representation:                                                                                                                                                1. The round size generally USES D to represent the diameter (because it is a special symbol to facilitate the current majority of people to use D to replace the diameter). For example, D8 by 2MM means a magnet with a diameter of 8 millimeters and a thickness of 2 millimeters. X is the mathematical notation for multiplication.                                                                                           2. The size of the square is long * style * height, and F is generally used to represent the square. For example, F30*20*10MM, that is, the square magnet is 30 mm long, 20 mm wide, 10 mm thickness, the default last number represents the magnetization of the square magnet, such as F30*20*10 square, magnetization is 10 mm direction, that is, the height of the direction of magnetization. NS is on the two largest faces, which is 30 by 20.                           3. The dimension of the ring is D* D* height. For example, a D20 by D10 by 6 ring magnet has an outer diameter of 20 mm, an inner diameter of 10 mm, and a height of 6 mm. Height is also called thickness. At present, the ring is also divided into straight hole and countersunk head hole, the hole is punched into the vertical, and countersunk head hole is divided into large hole and small hole depth and hole depth is commonly known as the screw hole.

Precautions for use:

1. Neodymium iron boron magnet is the most powerful magnet that people have invented at present.
2. Neodymium iron boron magnet is fragile. Its strong magnetic force will cause two magnets placed too close to each other to fly together, causing damage to the magnet. Large magnets should also be careful of flying debris to the eyes and other areas.
Ndfeb magnets rust easily, so the magnets are electroplated. Electroplating is only a surface layer, in the humid high temperature and other harsh environment electroplating can only be a period of time rust. Corrosive things should also be kept away from magnets.
4. Ndfeb magnet most avoid high temperature, general magnet maximum 80 degrees high temperature. The maximum temperature tolerance of magnets of different temperature classes is 80 100 120 150 180 200 230 degrees.
5. Keep credit CARDS, data storage CARDS, old monitors, televisions, etc. away from powerful magnets.
