Product Description

Neodymium magnet
Neodymium iron boron magnets can be divided into two types: bonded neodymium iron boron and sintered neodymium iron boron.The bond is in fact an injection molding, and sintering is a vacuum heating through high temperature molding.The neodymium iron boron magnet is a permanent magnet with the strongest magnetic force till now. Material grades have N35-N52.Various shapes can be processed according to specific requirements: round, square, punch, magnetic tile, bar, convex, trapezoidal etc.Despite these advantages, but the surface is easy to rust, so it is usually required to make a number of protective surface treatment:Nickel plating, zinc plating, gold plating, epoxy resin, etc.Ordinary NdFeB magnet suitable environmental temperature is below 80 degrees, but also has some ability to 200 degrees. Mainly used in electronics, electrical appliances, packaging, motors, toys, leather goods, automotive machinery, etc.

Characteristics of neodymium iron boron magnet
Neodymium iron boron magnet has the advantages of high cost performance and good mechanical properties.The deficiency lies in the fact that Curie's temperature is low, the temperature characteristic is poor, and the powder is easy to be corroded. It is necessary to improve the chemical composition and the surface treatment method to achieve the practical application.Neodymium iron boron belongs to the third generation rare earth permanent magnet material, which has the characteristics of small size, light weight and strong magnetic properties. It is a magnet with better performance and price than the best.
The advantages of high energy density make the neodymium iron boron permanent magnetic materials have been widely used in modern industry and electronic technology. In the state of bare magnetic, the magnetic force can reach about 3500 Gauss.
