As we all know, TDK is a company created by the invention of ferrites, which has always been the core competitiveness of magnetic products. Magnetic materials have their special meaning in every era. From the tapes in memory to the hard disk in the PC era, there are all kinds of magnetic materials such as iron, nickel, cobalt, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
At present, with the reform of the industry, the hard disk and PC market began to decline, the magnetic technology needs of rare earth materials may be restricted by some countries.
Therefore, not long ago, the most basic point of the so-called Magnet Renaissance proposed by TDK is material. A ferromagnetic material is one that has magnetic properties similar to those of iron. In other words, you can make a magnet out of it. Some other ferromagnetic materials are nickel, cobalt, and alnico magnets, an aluminum-nickel-cobalt alloy.
Now TDK has developed high-performance magnets without high rare earth elements (Dy and Tb) and high-performance ferrite Magnets without rare-earth elements.
Of course, the Magnet Renaissance proposed by TDK is not only reflected in the basic raw materials. For example, TDK’s new remote wireless charging technology, using the principle of magnetic resonance, is far more flexible than the current popular Qi standard charging. In the future, it can provide special applications including electric vehicles and long distance power transmission.
