Difference between NdFeB magnet and ferrite magnet

What is the difference between ferrite and NdFeB? What kind of magnet should I use? What are their advantages and disadvantages? Let's share with you today.
 
1、 In appearance
Ferrite: loose ferrite and no metallic luster, generally not electroplated, usually black.
Neodymium iron boron: neodymium iron boron basic must carry on the electroplating, otherwise very easy to rust. The surface has silver white metallic luster.
 
2、 Magnetically
Ferrite: ferrite magnetic force is usually 800-1400 Gauss, density is 5 (g / cm3)
Nd-Fe-B: the surface magnetism of Nd-Fe-B is usually more than 2000 GS, the maximum energy is more than 500 MT, and the density is 7.5 (g / cm3)
 
3、 Performance
Ferrite: ferrite temperature and stability are very good, in contrast, NdFeB ordinary temperature only 80 degrees. And the price is cheap.
Neodymium iron boron: neodymium iron boron has the characteristics of small volume, light weight and strong magnetism, and the magnetism is not the same level as ferrite.
 
4、 In terms of price
Ferrite: ferrite is cheap, many of which are calculated by piece, and the price has an impact on the shape, size and processing difficulty of ferrite.
Neodymium iron boron: now the price of neodymium iron boron almost changes day by day, depending on the brand and special requirements you need to use.
 
5、 Advantages and disadvantages
Advantages of Ferrite: the advantages of ferrite are high permeability, low price, high temperature resistance, suitable for low frequency occasions!
 
Disadvantages of Ferrite: poor magnetic force.
Advantages of NdFeB: strong magnetic force, high cost performance, wide application and good mechanical properties.
 
Disadvantages of NdFeB: poor temperature characteristics, fragile.
PS, the cheapest is ferrite magnetic steel, the highest performance is NdFeB magnetic steel, but the performance is the most stable.
 
As for the choice of ferrite or NdFeB, the key depends on where you use it? To control the cost, so as to choose, well, today to share here, tomorrow to continue!
