UNMAG Sintered Neodymium Magnets, also known as Rare Earth Magnets, are made from an alloy of neodymium, iron, and boron. These magnets provide the highest level of magnetic energy of any permanent magnet and can perform at temperatures up to 220°C. UNMAG Sintered Neodymium Magnets are available in a variety of shapes, such as blocks, rings, arcs, and customized shapes. Our magnets are certified with ISO9001, IATF16949, and ISO14001 standards and are packed in carton boxes, ready for delivery within 20-25 days.
Our UNMAG Sintered Neodymium Magnets are used in many applications, such as new energy cars, wind power generation, servo motors, and traction motors. They are available in a range of grades from N35 to N52, 35M to 50M, 35H to 48H, 30SH to 45SH. These magnets offer excellent performance and are capable of withstanding extreme temperatures.
UNMAG Sintered Neodymium Magnet is a rare earth permanent magnet with high performance. It is made from sintered neodymium iron boron powder and processed by special technology.
Sintered Neodymium Magnets can be packaged and shipped in bubble wraps and cardboard boxes. These materials help protect the magnets from potential damage from outside sources. The packaging should also feature a label with the product name, weight, and size. Additionally, the box should be marked with a “Fragile” sticker to alert the handling staff to take extra care. Special instructions may also be included for any additional handling requirements.
