Sintered NdFeB (neodymium iron boron) is the third-generation rare-earth permanent magnet material,
known as the \u201cmagnetic king,\u201d and is currently the strongest permanent magnetic material in the world,
with excellent magnetic properties. It is produced by mixing neodymium, iron, boron, and other trace
elements into alloy powders, which are then ground into powder, molded under pressure, and sintered
at high temperatures. Its main component is Nd2Fe14B. Due to its outstanding magnetic properties,
sintered NdFeB is widely used in various applications requiring high-intensity magnetic fields, such as
motors and generators, magnetic levitation technology, magnetic separation equipment, nuclear magnetic
resonance imaging (MRI) in medical devices, and consumer electronics such as headphones and
hard disk drives, etc.<\/p>\n\n\n\n
High magnetic performance: Sintered NdFeB magnets have extremely high magnetic energy product (BHmax),
typically ranging from 40 to 50 MGOe, with a maximum of up to 60 MGOe, which is more than ten times higher
than traditional ferrite magnets.<\/p>\n\n\n\n
High coercivity: They possess high coercivity, able to resist the demagnetizing effects of strong magnetic fields.<\/p>\n\n\n\n
Temperature stability: The maximum operating temperature for high-performance products can reach 200\u00b0C,
but it is generally recommended to use them in environments below 150\u00b0C to ensure magnetic stability.<\/p>\n\n\n\n
Machinability: Despite being relatively hard and brittle, sintered NdFeB can be processed into various shapes
through cutting, drilling, and other machining methods to meet different application requirements.<\/p>\n\n\n\n
However, sintered NdFeB is susceptible to corrosion from moisture and oxygen in the environment, so surface
coating treatment is usually required to prevent oxidation and corrosion. Common coatings include zinc plating,
nickel plating, nickel-copper-nickel plating, epoxy resin, etc.<\/p>\n\n\n\n
Alloy Melting
The main raw materials of sintered NdFeB permanent magnets are rare earth, iron and ferroboron, as well as
cobalt, aluminum, copper, gallium, etc. The prepared raw materials are melted into alloy flakes under vacuum.<\/p>\n\n\n\n
Hydrogen Decrepitation
Based on the hydrogen absorption and expansion principle of rare earth metals, alloy flakes are decrepitated into
millimeter grade NdFeB coarse powder, which is stored in sealed containers for anti-oxidation.
PERMANENT MAGNET has imported the continuous controlled atmosphere annealing furnace developed by Japan.<\/p>\n\n\n\n
Jet Milling
Driven by high pressure gas, the NdFeB coarse powder collides with each other and decrepitates, and the particle
size of the powder was refined to micron level to obtain the NdFeB fine powder. The fine powder is also stored in
sealed containers for anti-oxidation.<\/p>\n\n\n\n
Sintering&Annealing
After vacuum sintering and aging, NdFeB compacts can improve physical properties such as density, strength,
remanence and coercivity. PERMANENT MAGNET has imported several multi-chamber continuous vacuum
sintering furnaces.<\/p>\n\n\n\n
Machining
The sintered NdFeB compacts shall be machined into black sheet of various specifications and models. The machining
methods mainly include: coreless grinding, double-side grinding, linear cutting, slicing, drilling, holing, tapping, etc.
After machining, the specifications include: square, disc, circular ring, tile shape, special shape, etc<\/p>\n\n\n\n
Grain Boundary Diffusion
Different types and quantities of substances are directly introduced into the grain boundary region of the magnets to
react with the original grain boundary phase during sintering and subsequent aging process, so as to change the
composition and structure of the grain boundary phase, and to further improve the properties of the magnets and
reduce the addition amount of heavy rare earth in the magnets with high coercivity.<\/p>\n\n\n\n
Coating
Surface Treatment is an important means to improve the surface protection capability of magnets. PERMANENT MAGNET
has several full-automatic coating production lines to realize surface passivation, zinc plating, nickel plating, copper plating,
electrophoretic epoxy, vacuum aluminum plating, zinc-aluminum spraying, etc. of magnets, meeting the requirements of
different use environments of magnets.<\/p>\n\n\n\n
Inspection
PERMANENT MAGNET can carry out many testing items such as magnetic performance, service characteristics and element
analysis to provide reliable inspection guarantee and service for customers. The full-automatic inspection equipment makes
the inspection efficiency improved rapidly and the inspection data more accurate. The analysis and testing center of the company
has obtained the laboratory accreditation certificate issued by China National Accreditation Service for Conformity
Assessment (CNAS), becoming one of the few CNAS accredited laboratories in the industry<\/p>\n\n\n\n
Magnetizing
Through the instantaneous pulse strong current in the coil, the coil produces an ultra-strong magnetic field,
making NdFeB products magnetized.
The magnetization direction can be divided into thickness magnetization, radial magnetization, multipole magnetization, etc.<\/p>\n\n\n\n
Packing
Products are packed according to customer and company standards to suit the transportation requirements of cars, trains,
ships and airplanes, and to safely deliver to customers.<\/p>\n\n\n\n
