If you are perplexed because of the readily available grades of Neodymium or contemplating learning how a course is assigned to a certain Neodymium alloy, this post is for your needs.
N35, ND-35, and ND-3512 are comparable “Grades.” They represent a neo magnet alloy including an electricity Density (ideal power item) of 35 and has now an Intrinsic Coercive power of 12 kOe. The 12kOe causes a maximum working temperature for magnet of 80°C. (the particular optimum running Temperature is geometry centered as well as 150°C can be used here for illustrative purposes.)
N45SH, ND-45SH, and ND-4520 tend to be comparable class of Neo alloy. This notation presents a neo magnet alloy which has an electricity thickness (Maximum Energy item) of 45 and it has an Intrinsic Coercive power (Hci) of 20 kOe. The 20kOe is recommended within the high quality notation due to the “SH” suffix and results in a maximum operating temperature the magnet of 150°C. (the precise maximum Operating heat is geometry dependent therefore the 150°C is utilized here for illustrative factors.)
Neo Grade Explanation
As explained above, a Neodymium magnet’s “Grade” comes from the power thickness (maximum power Product) plus some sign associated with the Neodymium alloy’s ability to run at enhanced problems. Understanding the quality will not be adequate to anticipate a magnet alloy’s overall performance in an application. The Neo magnet’s grade have some other attributes which are acquainted with assess the magnet’s overall performance in an application. Unless the application form has reached back ground room temperature, the magnet has a Magnetic Length / Diameter ratio > 0.7, and there’s no extra demagnetizing fields, a performance evaluation is performed. Kindly engage a Dura application representative for support when choosing a Neo class for your application.
