With the continuous development of new industries, we know that magnets are used in many fields. But magnets are also divided into many types. The types of magnets are: sintered NdFeB, bonded NdFeB, SmCo, ferrite, rubber magnet, AlNiCo.
The raw material of the neodymium cube magnet balls is the neodymium iron boron magnet, which can be processed into a magnet toy in addition to industrial use. Ferrite is widely used in some high-end electronic and electrical products, and it is not easy to rust. Let’s find the reason. The main name of the ferrite magnet is triiron tetroxide: Fe3O4. It is already an iron oxide, so it is very difficult to be oxidized again. Other magnets (mainly iron) are made of magnetized metal iron or other elements. Like other irons and steels, it can be oxidized and rusted, and the magnetic part of the oxidized part disappears.
What are the characteristics of NdFeB and ferrite:
NdFeB: It has the highest performance, good price, good strength, and is not resistant to high temperature and corrosion. It can be processed into neodymium cube magnet balls. Now NdFeB magnets are widely used in our daily lives, including medical equipment, smart devices, and automobiles.
Ferrite: Ferrite has low and medium performance, lowest price, good temperature characteristics, corrosion resistance, and good performance-price ratio.
