To realize new magnet materials with high magnetic properties by replacing some of the basic composition of the magnet normaly has been brought without Dy (Dysprosium) and La (Lanthanum), Co (Cobolt). It is es-sential activities for eliminate raw material regional risk and price risk supplying the cost effective magnet sably and parmanently.

TDK has developed La,Co free ferrite magnet with high magnetic characteristics which is equivalent them of FB9 material including La and Co, and has established production and supply systems of Dy free neodymium magnet with high Br close to top Br value of NEOREC55 Series.

And TDK is applying "HAL", High Anisotropic field Layer, which is a kind of Dy grain boundary diffusion method, to the part of magnet with easy demagnetization area for enhance coercive force.

The thin wall molding process enables Br improvement and optimized shape, beyond conventional wet mold-ing technique in ferrite magnet, high power FB12, leads the world in the design for the development of next-generation motor to be compact and provide benefits.

TDK set up its global network in collaboration with the Manufacturing Department and the Marketing Depart-ment. We always pursue the best price performance through a highly efficient relational mass production system. We also actively promote the marketing of technology in principal client countries. Once we de-termine the latest technology trend in the applied prod-uct market, we predict forefront magnet needs in the future, and reflect these in the activities of the R&D Department as quickly as possible.

The core of the global network is the Shizuoka Plant, a pioneer of ferrite magnet production technology, and the Narita Plant, a technology innovation center of ne-odymium magnets and magnet applied products. Both plants employ creative and advanced technology for developing a highly efficient mass production line. They combine Materials & Process Development Center to establish mass production engineering methods for the latest materials, and also assume the role of a supplier to network plants all over the world.

Just like the "S"outh and "N"orth poles of a magnet, the "S" hizuoka Plant and "N"arita Plant are the main plants of TDK's Magnets to meet the desires of the magnet market into the next generation.

The dawn of a new century has been accompanied by numerous initiatives around the globe, involving the application of clean energy technologies.

Magnetic materials are poised to play a key role in both energy conservation and the preservation of resources and the environment. To expand the potential of ap-plied technologies and to introduce products thatuse the new technologies, the market is keenly awaiting methods for controlling physical properties and devel-oping highly efficient production systems.

TDK, founded as the world's first industrial supplier of original material ferrite, considers itself to be an "e-ma-terial solution provider " in this new century of clean energy. Supported by engineering efforts that have consistently tested new limits, we are strengthening our engineering ties and bolstering the technological ca-pacities of our Company.

The Ferrite & Magnet Products Business Group has been providing products to meet cutting-edge needs, includ-ing La, Co free ferrite magnet FB9RF and Dy free neodym-ium magnet NEOREC47HF, avoiding uneven distribution and quantitative risk of heavy rare earth and rare metals. But we have no intention of stopping with these achieve-ments. In the new century, we will continue our efforts to develop and deliver new magnetic materials that meet the needs of our clients, in every area of the market for applied magnet products.
