Magnet Manufacturer And Supplier

A permanent magnet is a magnet that does not lose its magnetic properties when the external magnetic field is removed. We also call them hard magnets. and another type of magnet we call a soft magnet that works like a temporary magnet. When an external magnetic field exited, it has magnetic properties, if the external magnetic field is removed, its magnetic properties will disappear.

There are types of permanent magnetic materials. Alnico Magnet is the earliest found permanent magnetic material, it works super stable in temperature changing, even at a high temperature of 550˚C. Neodymium Magnet is the strongest permanent magnetic material, which works widely in most industries. SmCo Magnet has good performance on working temperature and strong magnetic properties. FeCrCo magnet is the most machinable magnet. A Ferrite magnet is a low-cost magnet that supplies magnetic properties.

Choosing the correct magnetic material for your magnetic application is very important. Usually, when choosing magnetic materials, the main consideration is the magnetic properties. We can use software to simulate and make preliminary judgments on magnetic properties. These actions are often common in product design for large users. For example, our automotive sensor customers often use this method to provide approximate data requirements, and we can help customers provide the available performance of magnets. There are differences in the data, but the goal can be achieved by changing certain properties through the composition and process of the magnetic material. In addition, the application of magnetic materials needs to consider the application environment, especially the temperature. We need to consider the temperature coefficient of magnetism, that is, the change of magnetic properties per unit temperature change. Ensure the normal operation of the magnet.

The price of magnetic materials is mainly composed of material price and processing cost. Taking NdFeB as an example, the composition of NdFeB of different performance grades is different. Price changes play a major role. In terms of processing costs, taking NdFeB as an example, it is limited by the size of the molding press, and the processing price will be lower if the product size is relatively moderate and simple. Complicated shapes, extremely small sizes, or extremely large sizes will bring a difficulty to the processing of NdFeB magnets and increase the cost. Other magnetic materials are also similar. Therefore, customers need to know the price of magnets and need to pay attention to the price changes of materials of products. Mainly rare earth materials and precious metals cobalt and nickel.

For our magnetic material manufacturers, this is a strange problem, because they have no intersection in terms of magnetic performance and work performance, and there are few problems of application conflicts. Alnico has a very good high operating temperature and excellent stability, and the real advantage of ferrite is that it is cheap. But in the current application, in many acoustic product applications. will be mentioned frequently. In terms of acoustic performance, the surface of AlNiCo is much better, especially in the application of pickups. We have improved the production process of AlNiCo. The new process can make the cylindrical AlNiCo magnets no longer have internal pores, and the interior The crystalline consistency is better. For better acoustic performance of our Alnico pickup magnets.
