Driven by the high cost of samarium cobalt magnets, the NdFeB Compound was first discovered in 1982. Neodymium magnets are the strongest type of permanent magnet commercially available, today. HSMAG sells only patented, Hitachi-licensed sintered neodymium magnets. Neodymium has excellent characteristics: it has very high remanence and coercivity. It is possible to manufacture in a variety of shapes including radially-oriented magnets. Previously, at higher temperatures, only samarium cobalt was able to meet certain requirements. With the development of modern neodymium grades, some high temperature grades are able to exceed acceptable samarium cobalt temperatures. However, for most high temperature applications, samarium cobalt is still used based on a lower cost. Nevertheless, Neodymium is still one of the most widely used magnetic materials, today, because of its versatility, strong magnetic capability, and small relative size. Neodymium Ring Counterbore Magnet, sintered neodymium ring magnet, neodymium ring counterbore magnet

A powder metallurgy process is used to create sintered neodymium magnets. As is true of other magnets, it should not be used as a structural component. Neodymium is prone to corrosion, requiring an outer coating or plating. Typically, a nickel-copper-nickel or epoxy coating is the plating of choice. Other coatings are available, if required. As the sintered neodymium is being manufactured in a Nitrogen-infused vacuum, any air particles (particularly oxygen) will allow the magnet to corrode from the inside out. All HSMAG products are held to particularly rigid quality standards to control oxygen content and porosity. Patented processes are used to produce high quality magnets which are built to last. Sensor Permanent Magnet

Neodymium magnets typically have a higher temperature coefficient than other rare earth magnets. When the magnet is exposed to a higher temperature, it may lose part or all of its magnetic performance. Depending on the temperature and duration to which a magnet is subjected to, magnetic loss can be reversible. The recommended maximum operating temperature, residual induction (Br), and the intrinsic coercive force (Hci) should be considered when determining which magnet grade to use for your application.
