Samarium Cobalt magnets and Neodymium Iron Boron magnets are important Rare Earth Magnets. Many people want to understand how to use them, so we wrote this guide. Here we break down the important similarities and differences so you can quickly decide which is right for your application. So what are the basic differences between SmCo […]
Grain Boundary Diffusion is an important new advance in Neodymium magnet production technology. Heavy Rare Earth Elements (HREE) are delivered directly to critical areas of the magnet’s microstructure. These areas are where HREE are the most effective at increasing the properties of the magnet to withstand high opposing magnetic fields at high temperatures. HREE have […]
Magnetic Anisotropy is the capacity of a magnet to maximize its magnetic orientation in the direction of its poles, and it is similar to general anisotropy of other material characteristics.Strong permanent magnets – especially sintered Neodymium magnets- have had their magnetic domains oriented in the direction of the easy axis to maximize their strength. Anisotropy is […]
Coercivity is the resistance of a magnetic material to an opposing external magnetic field. There are two different kinds of Coercivity- Hcb and Hcj. The higher the Coercivity number, the higher the magnet’s resistance to the opposing field.Hcj vs HcbHcb is Normal Coercivity and Hcj is Intrinsic Coercivity.The Difference between Hcj and HcbHcb – is called […]
West Virginia University researchers are opening a new facility to capture valuable materials from a novel source – acid mine drainage from coal mining – turning the unwanted waste into critical components used in today’s technology-driven society. rare earth elements from Acid mine drainage Through a collaborative research and development program with the National Energy Technology […]
A central question that comes up in a magnet trade study is how to decide whether to use a Neodymium magnet or a Ferrite magnet for a particular application. A trade study that seems very simple at first glance can quickly become more complex once all the factors are considered. Designers who want to optimize their […]
Magnets made from rare earth metals are powering all sorts of gadgets that have become very important to our economy, and they are becoming more important for some really high-tech systems.
Apple CEO Tim Cook continued his China tour on Wednesday with an appearance at the Fortune Global Forum. He points out thatIt’s not so well known that China has become a world center of high-tech manufacturing, and Tim gives the Chinese educational system a lot of credit for that. They have created a class of […]
The current trade dispute between China and the United States will almost certainly influence the rare earth elements (REE) market in the not-so-distant future. First, let’s consider that U.S. President Donald Trump has threatened to raise tariffs on steel and aluminum imports invoking Section 232 of the Trade Expansion Act of 1962, which permits action based […]
A new recycling process developed at the U.S. Department of Energy’s Critical Materials Institute (CMI) turns discarded hard disk drive (HDD) magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste for valuable materials. Ryan Ott, a scientist at Ames Laboratory and a member […]
