                Ferrite tile is widely used in kitchen small household electrical appliances motor, treadmill motor, air pump, toy motor, vacuum pump motor, car window motor, servo motor, etcWhy ferrite tile material? Mainly because of the low price, it is...
                Some magnets with complex shapes are called special-shaped magnets for short. Because of the difficulties in production and processing, not every manufacturer does this. Dongguan carrich magnet factory is a professional manufacturer of spec...
                A mineral, magnetite; Magnet is not invented by people. There is natural magnetite. The first one to discover and use magnet should be Chinese. So the compass is one of the four great inventions of the Chinese people. As for the composition...
                The composition of the magnet is iron, cobalt, nickel and other atoms. The internal structure of the atoms is relatively special, and they have magnetic moment. Magnet can produce magnetic field and has the characteristics of attracting fer...
                The purpose of NdFeB magnet is to make compass, generator, electromagnetic ring, etc. ordinary people only think of it. No one knows that NdFeB magnet can also be used for beauty and disease elimination? Next, Jinhong magnetic technology (D...
                I believe that when it comes to this magnet, we will not be unfamiliar. Peculiar smell. Because the magnet is an indispensable part of the assembly of electronic components in many industries, and the special-shaped magnet is more able to m...
                NdFeB magnets can be divided into bonded NdFeB magnets and sintered NdFeB magnets. Bonding is actually injection molding, and sintering is vacuum pumping through high temperature heating molding! Neodymium iron boron magnet is the most powe...
                We all know that neodymium iron boron magnet can absorb 640 times of its own weight. Large powerful magnets are easy to hurt people when they are used. Why is demagnetization of NdFeB magnet? 1. Demagnetization or demagnetization after inj...
                Strong ferrite is a kind of non-metallic magnetic material, also known as ferrite. Ferrites is a kind of non-metallic magnetic material, also known as ferrite. It is made of Fe2O3 and one or several other metal oxides (such as nickel oxide,...
                As long as the material can be adsorbed on the special-shaped strong magnet, it can achieve the effect of distance magnetic field, and the thicker the material, the better the effect of magnetic separation. At present, the high-power magnet...
                Precision magnet? Magnet precision machining? What&#39;s the meaning of this? Carrich precision magnet manufacturer small edition on this issue briefly. Precision magnet, first of all, the two words precision are easy to understand, delicat...
                N52 brand NdFeB strong magnet has high magnetic energy product performance. N52 is a performance brand. According to the temperature coefficient, it can be divided into n-grade, m-grade, H-grade, sh-grade, etc. the surface Gauss of n52 5 * ...
                Yes, all of them can be drilled. The above figure shows a Nd-Fe-B arc-shaped magnet with countersunk holes. If you need this perforated tile magnet, you can contact us. Magnetic tile drilling needs certain technology and equipment, otherwis...
                As we all know, the processing of NdFeB magnets is basically carried out in a vacuum environment, and impurities are not easy to mix in. Because of the active chemical properties of NdFeB permanent magnetic materials, impurities are all inv...
                There are two kinds of motors for the UAV: one is the inner rotor and the other is the outer rotor. Inner rotor brushless motor means that the motor axis will rotate, the coil is in the motor shell, and the magnet is in the axis The outer r...
                The requirement of tool holder magnet is very simple, that is, it can absorb the tool, the tool does not fall off. But reality! Knife holder is a daily commodity, which needs to be promoted to seize market share. Malignant price competition...
