Neodymium-Iron-Boron Magnets NEOREC Series
INTRODUCTION
In recent years, small, high-performance rare-earth magnets have been in increasing demand for use in electronics equipment.
In 1977, TDK commercialized a 2-17 type REC magnet, solving the problem of high cost, the main drawback with conventional samariumcobalt magnets. It not only achieved better cost-performance, its superior performance was appraised as being the highest in the world.
The NEOREC magnet is a new product, surpassing the REC magnet. The main raw materials are neodymium, a rare-earth element, iron
and boron. Its magnetic characteristics at the mass production level reach 49MGOe in maximum energy product(BH), achieving 50 to
80% high performance with 10% reduction in specific gravity compared with samarium-cobalt magnets.
Ideal for meeting miniaturization and weight reduction needs for VCMs and other equipment. TDK offers a selection of custom magnets in
any shapes and sizes to meet customers’ requirements.
TDK also provides a range of technical services, including design of NEOREC magnet-applied products. For further information, please
contact TDK or your nearest representatives.

Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.

FEATURES/APPLICATIONS
FEATURES
• Magnetic characteristics at the mass production level reach 49MGOe in maximum energy product(BH) max, achieving 50 to 80%
higher performance than rare-earth cobalt magnet.
• The specific gravity is 7.4g/cm3 more than 10% lower than that of rare-earth cobalt magnet. Ideal for meeting miniaturization and weight
reduction needs.
• Higher mechanical strength such as bending and tensile strength than rare-earth cobalt magnets, making handling easier than before.
• Since the main raw materials are neodymium and iron, both abundant resources, stable supply is assured.
APPLICATIONS
Actuators for magnetic and optical disks, core-less motors, servomotors, stepping motors, MRI’s printers, sensors, magnetrons, klystrons,
magnetic bearings, magnetic couplings, etc.

IRREVERSIBLE DEMAGNETIZATION CHARACTERISTICS
The irreversible demagnetization characteristics of NEOREC magnets are dependent on their coercive forces and are not due to their
residual flux densities. There is no difference between the irreversible demagnetization characteristics of transversely and longitudinally
magnetized products.
