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 […]
Then why would you want to introduce hydrogen into a metal? Because we can use the same property to achieve our goal of reducing the grain size.
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 […]
Neodymium magnets are made by a sophisticated process that includes some very high-tech metallurgical methods comprising powder metallurgy and advanced process metallurgy.
Dozens of process steps must be followed very precisely to make Neodymium magnets –also known as NdFeB -for the chemical symbols of Neodymium, Iron and Boron.
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.
Small NdFeB Magnets in SmartphonesNeodymium (NdFeB) magnets are an invisible part of every smart phone. These tiny magnets are critical to the function of the phone, working quietly behind the scenes inside the phone case. These internal magnets are typically used in the speaker, receiver, vibration mode motor, taptic feedback motor, and camera auto-focus mechanism. […]
Honda Motor Company Ltd. along with Daido Steel Company have co-developed a new neodymium magnet with high heat resistance properties without the need for rare earth metals that will be used in the all-new Honda Freed and future hybrid vehicles. This new development will make the drive motors in electric vehicles cheaper to make because these […]
