Description
Sintered NdFeB magnet
Sintered Neodymium-Iron-Boron magnets are kind of rare earth magnetic material developed recently in1980’s, with magnetic properties far exceeding those of the Alnico and Ceramic/Ferrite types. They are alloys of elements, neodymium-iron-boron. The composition is Nd2Fe14B.
Sintered NdFeB magnets are the most powerful permanent magnetic materials commercially available, possessing high energy ranging from 30 MGOe to 50MGOe and wonderful coercive force. As the third generation of Rare Earth permanent magnets, NdFeB magnets are less brittle than SmCo. Sintered NdFeB has been widely used in high performance stepper, DC, servo, and linear motors, actuators, loudspeakers, headphones, instrumentation, switches, relays, magnetic imaging for medical and geophysical applications, holding systems, magnetic bearings, magnetic couplings, hard disk drives, etc..
Neodymium magnets are highly susceptible to corrosion. We offer a variety of coating and plating options to prevent corrosion and mechanical damage, such as Metallic Zinc, Nickel, Nickel+Nickel, Copper+Nickel, Nickel+Copper+Nickel, Gold, Organic Epoxy, Nickel+Epoxy coating.
Our neodymium disc magnets are mainly used in holding equipment. Some small disc magnets with lower energy are also used in auto speakers.
We can provide low energy neo material with competitive price for holding equipment or auto speakers. But our high energy like N50 or N52 is really powerful for high performance holding equipment.
You will find we are providing all lines of neo material with suitable price, we are expert to control the cost of neodymium magnets.
