NdFeB Permanent Magnet
NdFeB stands as the pinnacle of permanent magnet technology, meticulously engineered from superior raw materials. This remarkable magnet is composed of rare earth metal neodymium (29%-32.5%), iron (63.95-68.65%), and boron (1.1-1.2%), all skillfully augmented with a variety of elements, including dysprosium, niobium, aluminum, and copper. Through an intricate and precise manufacturing process, these elements unite to create the extraordinary permanent magnets that we proudly present to the market today.
Unleash the potential permanent powerful neodymium magnets, Mudi NdFeB magnets are crafted from premium sintered neodymium material. Coated with nickel, zinc, epoxy and gold, these magnets come in a variety of shapes including blocks, bars, cubes, discs, rings, cylinders, spheres, arcs and trapezoids with a density of 7.5-7.6 g/cm³. We guarantee fast delivery: 7-10 days for samples and 20-25 days for mass production. For superior magnetic properties, we explore grades N35-N52 and beyond, each with a specific operating temperature to ensure excellent performance even in extreme conditions.
