If you are perplexed by the offered grades of Neodymium or thinking about learning just how a course is assigned to a specific Neodymium alloy, this post is obviously for you.

N35, ND-35, and ND-3512 are typical similar “Grades.” They represent a neo magnet alloy including an electricity Density (ideal power item) of 35 and has an Intrinsic Coercive energy of 12 kOe. The 12kOe leads to a maximum running heat for magnet of 80°C. (this optimum running Temperature is geometry reliant as well as 150°C may be used here for illustrative purposes.)

N45SH, ND-45SH, and ND-4520 are comparable level of Neo alloy. This notation presents a neo magnet alloy which has had an electricity thickness (optimum Energy item) of 45 and possesses an Intrinsic Coercive energy (Hci) of 20 kOe. The 20kOe is recommended inside the quality notation because of the “SH” suffix and results in a maximum working heat the magnet of 150°C. (the particular maximum Operating heat is geometry centered and so the 150°C is employed right here for illustrative factors.)

Neo Level Explanation
As explained above, a Neodymium magnet’s “Grade” comes from the energy Density (optimum Energy item) many signal of the Neodymium alloy’s capacity to run at enhanced problems. Understanding the quality will not be enough to anticipate a magnet alloy’s functionality in a credit card applicatoin. The Neo magnet’s level may have some other attributes which are acquainted measure the magnet’s performance in a software. Unless the application is at history room-temperature, the magnet has actually a Magnetic Length / Diameter ratio > 0.7, and there is no extra demagnetizing areas, a performance evaluation is performed. Kindly engage a Dura application representative for support when choosing a Neo level for the application.
