Neodymium Motor Magnet Customization of Arc Shape NdFeB Magnets
Sintered NdFeB permanent magnet material is an energy storage device with high energy density, which can efficiently achieve the mutual conversion of energy and information. It is a fundamental functional material urgently needed by strategic emerging industries such as wind power generation, new energy vehicles, energy-saving motors, and hybrid vehicles.
There are many levels of NdFeB magnets
Grade | Max Operating Temperature | Grade | Max Operating Temperature |
N35-N48 | 80℃ (176℉) | 30SH-45SH | 150℃ (302℉) |
N50-N52 | 60℃ (140℉) | 30UH-45UH | 180℃ (356℉) |
30M-50M | 100℃ (212℉) | 28EH-38EH | 200℃ (392℉) |
30H-48H | 120℃ (248℉) | 28AH-35AH | 230℃ (446℉) |
Introduction of Manufacturing Process
Sintered Neodymium magnet is prepared by the raw materials being melted under vacuum or inert gas atmosphere in an induction melting furnace and processed in the strip caster and thus cooled to form alloy strip. The strips are crushed and pulverized to form a fine powder ranging from 3 to 7 microns in particle size. The powder is subsequently compacted in an aligning field and sintered into dense bodies. The blanks are then machined to the specific shapes, surface treated and magnetized.
Coating
Has a variety of conventional Ni-Cu-Ni, Zn, black epoxy coating. after plating, has a good rust, corrosion resistance.Corrosion resistance: black epoxy> Ni-Cu-Ni > Zn.
