Comparison of surface magnetic and tensile forces of neodymium iron boron and ferrite with specifications D10 * 2mm Customers often ask about the difference in surface magnetism and magnetic force between different materials of the same specification. Today, the editor has compiled magnets with a diameter of 10mm and a thickness of 2mm from different materials of the same specification to share with everyone.Comparison of magnetic field strength between D10 * 2mm neodymium iron boron and ferriteThe 10x2 powerful magnet is about 2200 Gauss, and the Gauss values of silver nickel plating and black epoxy plating are the same, except for the difference in surface coating. If a 10x2 ferrite magnet is used, the surface magnetism will be in the range of 600 to 700 Gauss.10mm x 2mm neodymium magnetComparison of tensile strength between D10 * 2mm neodymium iron boron and ferriteThe vertical tensile force of 10 * 2mm neodymium iron boron is about 1.44kg, while the vertical tensile force of ferrite of the same specification is only about 0.14kg.: 23

Introduction to Irregular Beveled Spiral Magnetic Tiles as the Leading Actor in the Field of Motor Energy Conservation In our daily lives, square magnets, circular magnets, cylindrical magnets, circular ring magnets, countersunk hole magnets, etc., should be familiar to everyone and often come into contact with. But some magnets, such as spiral tile magnets, should be unfamiliar to most people. Below, the magnet manufacturer will briefly introduce the irregular bevel spiral magnetic tile.Neodymium iron boron spiral magnetic tileSpiral tile magnet, also known as inclined edge tile magnet, is currently widely used in the field of energy-saving motors, injecting new energy into the energy-saving of motors.Due to its unique shape, the machining process is extremely complex. Generally, it is necessary to first draw a simulation diagram using CAD software to obtain relevant data, and then perform multiple polishing and cutting before forming.Often, processing a spiral tile magnet requires about 4 times the amount of raw material. So the labor and material costs are relatively high.: 23

What is high-temperature demagnetization? Firstly, what is high-temperature demagnetization?High temperature demagnetization refers to demagnetizing a demagnetized product (neodymium iron boron magnet) in a high temperature environment. The principle is that in a high temperature environment, if the temperature is greater than the Curie temperature of the magnet and the thermal movement of the magnet molecules causes the magnetic moment to rearrange in a disorderly and disorderly manner, with different directions, and the overall external manifestation is demagnetization, which is the principle of high temperature demagnetization.What are the methods or equipment for high-temperature demagnetization of neodymium iron boron?Heating magnetThe neodymium iron boron series magnets can be demagnetized using hot oil, with an oil temperature usually reaching 80-200 degrees Celsius, which can completely eliminate magnetism. The disadvantage of using this method is that the oil film generated on the surface of the product after hot bath: 23

The main specifications of neodymium iron boron permanent magnets have a significant impact on motor performance The remanence index is the maximum magnetic flux intensity that a magnet can provide after being magnetized without an external magnetic field. The larger the value, the higher the magnetic density of the magnet's air gap, and the higher the maximum torque and efficiency point.Coercive force is a parameter that represents the ability of a magnet to resist demagnetization. The larger the value, the lower the thickness of the magnet during motor design, and the stronger the ability to resist overload;The maximum magnetic energy product represents the maximum magnetic energy that a magnet can provide to the outside world. The higher the value, the less magnets will be used at the same power.The Curie temperature Tc is the temperature point at which the magnetic properties of the magnet disappear, indicating the temperature range within which the magnet can operate.And the temperature coefficientα If it is a magnet, it represents the percentage of reversible changes in the magnetic pro: 20

Introduction to Countersunk Hole Magnets Countersunk magnet, also known as a counterbore magnet, is a powerful counterbore magnet that is installed and fixed in the desired position through screws. The size of a countersunk hole magnet is generally represented by a large D for diameter, d1 for countersunk hole diameter, d2 for straight hole inner diameter, and H for thickness (height).Speaking of this type of magnet, do you really feel unfamiliar? Let me give a few examples now to see if you are familiar with it. There are some large screws on the toys of children at home, especially those robots. Although it may seem easy to unscrew them, it is really difficult to handle them in practice. It feels like something is sucking on them, This is a special type of circular counterbore magnet: screw hole magnet.Our company can customize any size and performance of neodymium iron boron countersunk hole strong magnets, high-temperature resistant countersunk hole magnets, square rectangular double countersunk hole magnets, circular cou: 20

You should know the difference between same-sex ferrite and heterosexual ferrite Is there a difference between same-sex and heterosexual ferrite? Yes. Recently, the editor encountered a customer from Tangxia who was not clear. Some merchants provided him with same-sex ferrite, which caused the sample to be delayed and unqualified. Finally, we found out and helped the customer solve the problem.What is the difference between isotropic and anisotropic ferrite magnets? What is the difference?The magnetic energy product is about three times more anisotropic than isotropic, and when making it, isotropic is simpler than anisotropic. Therefore, same-sex molds will be slightly cheaper compared to their unit price.How to distinguish between same-sex or heterosexual ferrites based on their appearance?This cannot be seen from outside. Isotropic magnetic fields are applied during compression (dry or wet) to align the easily magnetized axes of the magnetic powder.How much Gaussian is there on the surface of isotropic ferrite? How much Gaussian can anisotropic ferrite reach?Homo: 20
