Customers should pay attention to the following matters when using ferrite magnets.

 

Ferrite magnetic material is hard and brittle, so it should be gently taken and placed (especially large size and sheet). When the magnet itself or is attracted or separated from other iron devices, it should be carefully operated without impact. Otherwise, it is easy to cause collision and damage the magnet or hurt the finger. Because Ferrite Permanent magnet belongs to multi-metal alloy material, ceramic technology, has the characteristics of heavy and brittle, so be careful when carrying and holding, so as to avoid magnetic crushing, breaking and breaking. When the magnets can't be drawn and separated from each other, it is recommended to push them horizontally and stagger them, and do not pry them hard.

 

[1] Circular size generally uses D to indicate the diameter (because it is a special symbol for convenience, most people use D instead of Φ at present), for example, D10X3MM indicates the diameter is 10mm, the thickness is 3mm magnet. X this is the mathematical symbol "multiplication sign".

 

[2] The square size is length x width x Height. Generally, F is used to represent the square. For example, F20x10x4MM indicates that the length of the square magnet is 20mm, the width is 10mm, and the thickness is 4mm. Generally, by default, the last number indicates the magnetization direction of the square magnet, for example, for a F20x10x4 square, the magnetization direction is 4mm, that is, the height direction is magnetized. NS is in the two largest faces, that is, 20x 10 faces. At present, squares are also divided into straight holes and countersunk holes. The straight holes are inserted vertically, while countersunk holes are divided into large holes and small holes. Besides, the depth of large holes and small holes are commonly known as screw holes.

 

[3] The size of the ring indicates the height of the outer diameter D inner diameter D. For example, a D32XD18X6 ring magnet indicates 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 straight hole is inserted vertically, while the countersunk hole is divided into large hole and small hole, and the depth of large hole and small hole are commonly known as screw holes.

 

[4] spherical magnet, which means simple diameter D. For example, D5MM indicates magnetic ball with a diameter of 5mm.

NdFeB magnet: NdFeB is the magnet with the highest commercial performance found at present, which is called magneto. It has extremely high magnetic properties and its maximum magnetic energy product (BHmax) is more than 10 times higher than Ferrite (Ferrite). Therefore, it is also commonly known as: strong magnetic, magnetic steel, etc. Its own mechanical processing performance is also quite good. The working temperature can reach up to 200 degrees Celsius. And its texture is hard, its performance is stable, and it has good cost performance, so it is widely used. But because of its strong chemical activity, its surface layer must be treated.

NdFeB permanent magnet material is a permanent magnet material based on intermetallic compound Nd2Fe14B. Compared with casting Al-Ni-Co series permanent magnet materials and Ferrite Permanent Magnet Materials, NdFeB has extremely high magnetic energy product and coercive force, and can absorb 640 times of its own weight. The advantage of high energy density makes NdFeB permanent magnet materials widely used in modern industry and electronic technology, thus making instruments, electroacoustic motors, magnetic separation magnetization and other equipment small, lightweight, thin becomes possible. Material characteristics NdFeB has the advantages of high performance-price ratio, good mechanical characteristics and easy cutting and processing. The disadvantage lies in low Curie temperature point, poor temperature characteristics and easy pulverization and corrosion, only by adjusting its chemical composition and adopting surface treatment methods can it be improved to meet the requirements of practical application.
Manufacturing process NdFeB is manufactured by powder metallurgy, which will contain a certain proportion of raw materials such as neodymium, dysprosium, iron, cobalt, niobium, praseodymium, aluminum, copper, boron and iron are smelted into medium frequency induction melting furnace by alloy steel ingot, then broken into 3 ~ 5cm powder, and pressed and formed in magnetic field. The formed green body is sintered in vacuum sintering furnace and tempered for aging, in this way, a permanent magnet blank with certain magnetic properties is obtained. After grinding, drilling, slicing and other processing procedures, the finished NdFeB product required by users is obtained after surface treatment.
