Product Description

NdFeB Trapezoid Magnet with Mark

Sintered NdFeb permanent magnetic material has excellent magnetic properties, widely used in electronics, power machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields, the more common are permanent magnet motor, speaker, magnetic separator, computer disk drive, magnetic resonance imaging equipment and instruments.

Technological process: batching melting ingot/strip spinning powder making press sintering tempering magnetic testing grinding pin cutting electroplating finished product.

Among them, batching is the basis and sintering tempering is the key.

Production tools and performance testing tools for NdFeb magnet blank: melting furnace, strip blast furnace, hydraulic fracturing machine, air flow grinding, pressing molding machine, vacuum sealing machine, isostatic press, sintering furnace, heat treatment vacuum furnace, magnetic properties tester, Gaussimeter.

Ndfeb magnet machining tools: centerless grinding, rolling machine, double end grinding, flat grinding, slicer, double side grinding, line cutting, bench drill, special-shaped grinding, etc.

Neodymium iron boron, also known as NdFeB magnet (NdFeB magnet) is a tetracrystal formed by neodymium, iron, boron (Nd2Fe14B).

Neodymium magnets were discovered in 1982 by Masato Sagawa of Sumitomo Special Metals in Japan.

The BHmax of this magnet was greater than the BHmax of a samarium cobalt magnet, the largest mass in the world at that time.

Later, Sumitomo Special metals developed successfully powder metallurgy process.

General Motors developed the melt-spinning process, which produced NdFeb magnets.

This magnet is the most powerful permanent magnet and the most commonly used rare earth magnet.
