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.
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)
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.
