Properties of hot-pressed and hot-deformed NdFeB magnets Hot-pressed and hot-deformed NdFeB magnets were successfully researched and developed almost simultaneously with sintered NdFeB magnets. In 1985, the General Motors Corporation (GM) Research Center of the United States reported that using hot pressing technology to press the quenched NdFeB magnetic powder in an argon environment at 700 [...]
Preparation process of sintered NdFeB magnets (1) - Raw material Today we start with the link of raw material preparation and alloy preparation. Sintered magnets usually use pure metals or intermediate alloys as raw materials, use the electromagnetic induction heating principle of eddy current generated by alternating magnetic fields in the raw materials, and conduct [...]
Preparation process of sintered NdFeB magnets (2) - Milling powder In the previous issue, we learned about alloy smelting and casting. After casting, the alloy needs to be made into powder through a pulverizing process before entering the subsequent processing process. Obtaining suitable powder shape, average particle size and particle size distribution is the basic [...]

Sign up to the free mailing list to get beautiful visualizations on natural resource megatrends in your email every week. Rare earth elements are a group of metals that are critical ingredients for a greener economy, and the location of [...]
New Type EV Motor, Use No Magnet MAHLE's new, inexpensive and efficient EV motor does not use magnets. Magnets usually made of rare earth metals such as neodymium are found in the heart of most electric vehicles. Having a permanent strong rare earth magnetic field in the rotor is a good choice, because using a [...]
Frequently Asked Neodymium Magnets Questions What is Rare Earth? Rare earth is an ore primarily mined in China. Rare earth is the source of 17 elements listed on the periodic table as Lanthanides. Two of those elements Neodymium and Samarium are the magnets namesakes that are derived from the rare earth ore. Both Neodymium (Nd) [...]
Three Major Events of Rare Earths Recently, the international topic on rare earths has increased significantly. Rare earth is a strategic material that is widely used in military, industrial, agricultural and other industries. It is an important support for the manufacture of new materials and an important resource related to national defense and security. It [...]
Programs for Recycling Rare Earth Metals Have you ever wondered if you can recycle magnets? Previously, old magnets could not be recycled to reuse the rare earth metals inside them, but new methods have been developed that have made it worthwhile to reuse the material inside magnets. Magnets made with rare earth metals are used [...]
The Future of Cerium And Its Effects On the Permanent Magnet Industry Cerium, for one, is not a useable component of current permanent magnet creation, but nonetheless is critical to the health of the industry. However, the way established markets run for rare earth metals, sister minerals mined must be a significant factor when calculating [...]
Permanent Magnet Industry On The Rise In spite of sluggish behavior in related tech markets, the permanent magnetic market is in the throes of a substantial upswing with the money-saving factors of thrift and responsibility in regards to energy efficiency while witnessing a global increase in electrification. The growth stems primarily from automotive concerns as [...]
Researchers Developing Sustainable 3D Printed Super Magnets An additive manufacturing breakthrough coming out of TU Graz in Austria could make it easier to manufacture permanent magnets for small electronic components. A TU Graz team—working in collaboration with the University of Vienna, the Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) and Joanneum Research—has successfully manufactured super magnets using a [...]
Are Rare Earth Magnets Metals Really “Rare”? Rare Earth Magnets Metals Rare Earth Magnets Metals/Rare Earth Metals are a gathering of 17 metallic components with comparative properties and structures that are crucial in the assembling of a various and extending show of high-engineering provisions. They are basic segments in hi-tech items including advanced cells and [...]
