Bonded Neodymium Magnet
Bonded Neodymium Magnet
The bonded neodymium magnetis manufactured by mixing the NdFebmagnetic powder and the bonding agent. Since its successful development in1988, this material has enjoyed rapid development and its output has grownexponentially. As a type of high performance permanent magnetic material, thisproduct features small size, light weight, and thin thickness, meeting thedevelopment trend of electronic products.
This material ismanufactured at one time and no secondary processing is needed. It has higherprecision than the sintered type and can be made into many complicated shapes.Using this material in a motor can greatly reduce the size and weight of themotor.
Our company has 6 years of experience in marketing the bonded neodymium magnet.We mainly export product to Americaand Swiss. Generally, this product is used for the office automation equipment,electric machinery, audio-visual equipment, instrumentations, small motors,measuring instruments, mobile phone vibration motors, driving motors for CD-ROMand DVD-ROM, hard disc drive, as well as other micro DC motors.
