Common magnetization directions are shown in the figure below:

1> Cylindrical, disc and ring magnets can be magnetized radially or axially.

2> Rectangular magnets can be divided into thickness magnetization, length magnetization or width direction magnetization according to the three sides.

3> Arc magnets can be radial magnetized, wide magnetized or coarse magnetized.

Coating and Plating

Sintered NdFeB is easily corroded if without coating , NdFeB magnet will be oxidized when exposed to the air for a long time, which will eventually cause sintered NdFeB product powder to foam, that is why the periphery of sintered NdFeB needs to be coated with anti-corrosion Oxide layer or electroplating, this method can protect the product well and prevent the product from being oxidized by air.

Common plating layers of sintered NdFeB include zinc, nickel, nickel-copper-nickel, etc. Passivation and electroplating are required before electroplating, and the degree of oxidation resistance of different coatings is also different .

production process

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.
