Yiwu Haorui Magnet Factory was established in 2006, the company specializes in the production of Ndfeb, ferrite, rubber magnet! After nearly ten years of development, has become an annual production capacity of NdFeb magnets up to 100 tons, ferrite magnets 1000 tons, pre-burning 20,000 tons of large-scale magnet production enterprises. The company covers an area of 80 acres, 456 employees, 46 people with college education or above, our company produces more than thousands of products, products are widely used in all kinds of loudspeakers, packaging boxes, jewelry, toys, DC motors, household appliances, medical equipment, computers, aerospace, measuring instruments, Electronic watches, hardware tools and other fields of products are mainly sold to Japan, the United States, Australia, Italy, Hong Kong and Taiwan and other countries and regions.

Our company has been tested by the market for many years, small size NdFeb, small size square, small size ferrite, cutting ferrite price advantage is invincible!
The company has strong technical force, first-class production equipment, advanced technology, perfect testing means and strict quality assurance system, and passed the ISO9001:2008 quality system certification in 2009.
The company pursues the ";quality-oriented, customer first, small profits and quick sales" the enterprising spirit of enterprise as the business philosophy, to "create value for employees, create benefits for customers, and strive for the development of China's magnetic material industry for life!" For the mission will continue to provide excellent quality and competitive magnetic products. Warmly welcome customers to inquire!

Customers need to know the following before purchasing Ndfeb magnets

First, the magnet belongs to NdFeb rare earth permanent magnet, which is a strong magnet, and is currently found to have the highest commercial performance of magnets. The strongest magnetic material is well-deserved strong magnetic. Because of its excellent magnetic properties and known as "magnetic king, please rest assured to buy, careful use."

Second, the specifications produced by our company are round, square, round, shaped, trapezoid, tile, spherical, irregular graphics and other Ndfeb strong magnets, can be customized production. All of our magnet sizes are measured in millimeters.

[1] The circular size is generally used to indicate the diameter of D (because it is a special symbol for the convenience of most people use D instead of Φ), such as D10X1MM indicates a magnet with a diameter of 10 mm and a thickness of 1 mm. X This is the mathematical symbol "multiplication".

[2] The size of the square is length X width X height generally denoted by F square. For example, F50x25x13MM, it means that the length of the block magnet is 50 mm, the width is 25 mm, and the thickness is 13 mm. Generally, a number at the end of the default indicates the magnetization direction of the square magnet, such as the F50x25x13 square, the magnetization direction is the direction of 13MM, that is, the height direction. NS is on the two big faces, which is the 50x25 face.

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

[4] Spherical magnet, expressed 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 brands of NdFeb magnets, as follows:

N35 N38 N40 N42 N45 N48 N50 N52 The maximum operating temperature is 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 The maximum operating temperature is 150 ° C
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 degrees

33, 35, 38, 40, etc., represent large magnetic energy products. The strongest magnetic energy product of N33 NdFeb material is about 33MGOe. The strongest magnetic energy product of N35 NdFeb material is about 35MGOe. The maximum magnetic energy product of the N40 material is about 40MGOe. The conversion of MGOe and kA/m3 is 1MGOe = 8kA/m3, that is, the strongest magnetic energy product of N40 is about 320kA/m3. The higher the grade, the stronger the magnetism, the higher the corresponding price, so the specific need to be determined according to the actual needs of customers. Under normal circumstances, such as packaging, machinery, stationery and other products with low requirements are mainly n33. Most of the low-grade horn magnets are n35.

Sintered NdFeb magnet, has an unimaginable super magnetic force, sintered NdFeb magnet theoretical maximum suction is hundreds of times its own weight, is currently the most powerful permanent magnet. Of course, the bigger the magnet, the stronger the magnetic force.
