If you've ever purchased a NdFeB magnet, you surely know that almost all NdFeB magnets have a coating, so why don't ferrite magnets need a coating? First of all, let us know about ferrite magnets, which are non- metallic magnetic materials, also known as magnetic ceramics, so there is basically no corrosion problem. It can be seen everywhere in life. For example, the speaker magnet in the radio is...
We have been trading in the magnet industry for many years. A small number of customers indicated that the magnetic force of the permanent magnets they purchased was attenuated, and they usually suspected that it was the quality of the product itself. In fact, the quality of our products can stand the test of the market.Today let's take a look at what factors lead to demagnetization of permanent m...
Many people know that the characteristic of magnets is that they can absorb iron. Magnets can be used in many ways. How long magnetic properties last is perhaps a matter of concern. Many people say that magnets can convert electrical energy into mechanical energy and mechanical energy into electrical energy. Because of this, the position of magnet in modern industry is irreplaceable. It is widely ...
Ferrite magnet has many applications in our life. Ferrite magnet is a permanent magnet mainly made of SrO or BaO and Fe2O3 as raw materials. Ferrite magnets are hard and brittle and have lower magnetic energy than other permanent magnets. But it is not easy to demagnetization corrosion, simple production process and low price, therefore, in the whole magnet industry ferrite magnet output is the hi...
Today we are going to talk about the installation of motor magnets need to pay attention to it! First, pay attention to magnetic poles When installing the magnet, we must pay special attention to the N pole and S pole of the magnet, otherwise it will get twice the result with half the effort. You can remind our salesman to mark the magnets for you during production so that you can better distingui...
The pricing of a product in an industry needs to comprehensively consider various factors, such as material price, market situation, labor, technology, strength, brand, profit and so on. Of course, there will be factors of the manufacturer itself. Many customers will directly ask what the price of such powerful magnets is? In fact, the price of strong magnet is related to many factors and is not f...
Permanent magnetic materials are also called "hard magnetic materials". A material that maintains constant magnetism once magnetized. It has wide hysteresis loop, high coercivity and high remanence. Permanent magnetic materials are materials with wide hysteresis loop, high coercivity and high remanence, which can maintain constant magnetism once magnetized, also known as hard magnetic materials. T...
With the development of society, magnets are more and more widely used, from high-tech products to the simplest magnetic packaging. At present, Nd-Fe-B magnets and ferrite magnets are most widely used. From the development history of magnets, man-made magnets appeared in the 18th century, but the process of manufacturing stronger magnetic materials is very slow. At the end of the 19th century and ...
Production technology of Nd-Fe-B magnet 1. Raw material preparation and pretreatment: Process Description: pretreatment of raw materials such as weighing, crushing, material breaking and rust removal. Process equipment: steel bar cutter, drum polishing machine, etc 2. Melting: Process Description: the pretreated raw materials praseodymium neodymium, pure iron, ferroboron, etc. are proportioned and...
There is no standard? how can I choose the right grade of magnet for me？ We often confirm below several elements with the customer before quoting the price 1.Product dimensions and shapes:disc magent,blcok magnet,arc magnet or ring magnet） 2.Material & grade(we can judge what type of magnets you need by the grade you give:Neodymium magnet,Ferrite magnet,Alni...
