Neodymium magnets are found that the commercialization of the highest performance magnets, known as Magneto, has a very high magnetic can be higher than the maximum energy product (BHmax) ferrite (Ferrite) 10 times more. Neodymium magnets’ machining performance is also quite good. Operating temperature is up to 200 degrees Celsius. And neodymium magnets have hard texture, stable performance, good price, so that their application is extremely broad. But because of their strong chemical activity, so neodymium magnets’ surface is coating. (Such as Zn, Ni, electrophoresis, passivation plating, etc.).

　　The neodymium magnets Sumitomo Special Metals Corporation Sagawa real people invented in 1982, known by its chemical formula is mainly composed of chemical elements such as neodymium, iron and boron.

　　Nowadays, neodymium magnets have rapid development and a wide range of applications. In many areas is likely to replace the traditional pure iron magnets, alnico and samarium cobalt magnets, such as motors, instruments and meters, automotive industry, the petrochemical industry and magnetic health care products. Capable of producing a variety of shapes: for example disc magnets, ring magnets, rectangular magnets, arc magnets and other shapes of neodymium magnets.

　　Daily electronic products, such as hard drives, mobile phones, headsets, and so on, there is the presence of neodymium magnets.

　　Play an increasingly important role in the field of professional audio neodymium magnets. Due to the small size of neodymium magnets, light weight, large magnetic flux. It is very suitable for professional performance stage PA and major sports venues PA. TM brand professional audio in a number of professional audio brand has been through a lot of experiments to develop a variety of high-quality neodymium magnets unit and upgrading traditional line array sound unit developed LA-102F power, compact lightweight neodymium magnets unit line array performance speakers.
