Sintered Neodymium Iron Boron (Sintered NdFeB)
Due to over 20 years of continuous development the Neodymium Iron Boron Family has evolved over 30 grades based on the maximum energy product and operating temperature. Some grades have become obsolete as laboratory curios become factory product. Some factories are now claiming operating temperatures as low as 50ºC and up to 230ºC for specialist use. MagDev source from several factories and a summary of the range of grades is shown below. Please note that not all sizes are available in all grades. It is wise to seek assistance during the concept stage of product design to establish what we can offer.
Sintered NdFeB Magnets
NdFeB magnets offer the highest energy per unit volume of any permanent magnet material, it can lift up to 1000 times its own weight. It is manufactured in numerous energy and temperature grades, current energy levels start at 33 MGO, up to 50 MGO.
All grades including SH (high temperature) 150°C degree materials still have a poor temperature coefficient, losing approximately 0.10% of Remanence per °C. These losses are called Reversible Losses and the Remanence will recover as the temperature falls.
The material is available from stock in various standard block and disc sizes Non standard sizes are also available. Applications for Neodymium magnets are wide ranging and are used extensively within many industries including Aerospace, Automotive, Medical and renewable energy.
