NdFeB Magnet Technical Data
More Grade Options Available
Our knowledgeable engineering department is always available to assist in determining the best grade and size of neodymium magnet for your application.The temperature coefficient of neodymium has triggered several grades to be developed to meet specific operating requirements. Please refer to our chart of magnetic properties to compare the characteristics of each grade. Before choosing a neodymium magnet be sure to consider your application’s maximum operating temperature.
