The difference between NdFeB magnet and ferrite magnet

Xiamen everbeen has received many inquiries about ferrite from customers. Xiamen everbeen focuses on the production of neodymium iron boron, and of course it also manufactures ferrite. This shows that many customers cannot distinguish between NdFeB and ferrite. Today, I will analyze the difference between NdFeB and ferrite.



Both neodymium iron boron and ferrite are magnets, but the two are essentially different. The analysis is as follows:


1. Appearance: Ferrite has a relatively large specification, generally not electroplated in loose quality, and is black in natural color. The small size of NdFeB requires surface anti-rust treatment, such as nickel-plated zinc-plated epoxy, etc.


2. Magnetism: ferrite magnetism is usually ordinary magnetism, and neodymium iron boron is strong magnetism.


3. Price: Ferrite is relatively cheap: NdFeB needs to be determined according to the performance brand used, and the price is relatively expensive.


4. Features: Ferrite has high magnetic permeability, low price, strong temperature resistance, and is suitable for low frequency use! Neodymium iron boron has strong magnetic force, is widely used, and has good mechanical properties.


Neodymium iron boron (NdFeB) permanent magnet material is a permanent magnet material based on the intermetallic compound Nd2Fe14B. Neodymium iron boron has extremely high magnetic energy product and coercivity, and can absorb 640 times its own weight. The advantages of high energy density make neodymium iron boron permanent magnet materials widely used in modern industry and electronic technology, making it possible to miniaturize, lighten, and thin equipment such as instrumentation, electroacoustic motors, and magnetic separation and magnetization.


Ferrite magnets are composite oxides composed of iron oxides and one or more other metal oxides (such as BaO·6Fe2O3, MnO·Fe2O3·ZnO·Fe2O3, etc.), which are called ferrites. Ferrite with ferrimagnetism is a kind of strong magnetic material, commonly known as ferrite magnetic material. The use and variety of ferrite magnetic material have been increasing with the development of production. According to the application, ferrite can be divided into five categories: soft magnetic, hard magnetic, gyromagnetic, moment magnetic and piezomagnetic.


Summary: There are essential differences between ferrite and neodymium iron boron. Xiamen everbeen is a manufacturer of neodymium iron boron magnets, welcome to visit the factory and order!
