Our company has been doing foreign trade for more than 2 years. During this time, I found that there are still many inquiries about neodymium magnets. The advantages of choosing more are explained. The advantages are still quite big. Today, this article will introduce the advantages of strong neodymium magnets. and shortcomings.
First, let's talk about the advantages;
1、NdFeB permanent magnet material is a permanent magnet material based on intermetallic compound Nd2Fe14B, which has extremely high magnetic energy product and coercive force, and the advantages of high energy density make NdFeB permanent magnet material in modern industry and electronic technology. It has been widely used, which makes it possible to miniaturize, lighten, and thin equipment such as instruments, electroacoustic motors, and magnetic separation and magnetization.
2、Strong magnetic force, it is the strongest magnetic material at present, and it is widely used and cost-effective.
3、With good mechanical properties, it can be easily processed into various shapes, including special-shaped magnets.
4、Cost-effective
5、High precision, tolerance can be controlled to ±0.02mm
Disadvantages of Neodymium Magnets;
1、Curie temperature is low
2、Poor temperature characteristics
3、The surface must be electroplated. Many customers have asked if the surface is not plated? If you don't want to use it and then scrap it, it has to be plated.
4、Fragile. This is the characteristic of a magnet. The stronger the magnetic force, the easier it is to break
The above is an introduction to the advantages and disadvantages of rare earth neodymium magnets. It was originally edited by Karich magnet manufacturers in China. If you have any doubts, please consult.
