HCNTP70HL Density(g/cm3) 5.31 NdFeB Compound
What is NdFeB compound?
Neodymium iron boron compound is one of the most widely used rare earth magnet compounds. It is a permanent magnet made of an alloy of neodymium, iron and boron, forming a tetragonal crystal structure of Nd 2 Fe 14 B.
The uncoated nano (Royce3010) chelate film can meet the use in marine climate conditions for 20-30 years, and can be widely used in sea-based wind power generation. The surface bonding force is greater than 20Mpa, which can be widely used in permanent magnet high-speed motors, special motors, electric vehicle motors, extra-high voltage, high-voltage DC power supply systems, fast charging systems, aerospace, military industry, etc.
NdFeB compounds have excellent magnetic properties and are widely used in electronics, motors, medical devices, toys, packaging, hardware machinery, aerospace and other fields. The more common ones are permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment and instruments

Material characteristics
NdFeB has the advantages of high cost performance and good mechanical processing characteristics; the disadvantages are low Curie temperature point, poor temperature characteristics, and easy to powder corrosion, it must be improved by adjusting its chemical composition and surface treatment to meet the requirements of practical applications.
Characteristics
NdFeB permanent magnet material is based on intermetallic compound Nd2Fe14B. NdFeB has very high magnetic energy product and coercive force, while the advantages of high energy density make NdFeB permanent magnet material widely used in modern industry and electronic technology, which makes it possible to miniaturize, lighten and thin the equipment of instrumentation, electroacoustic motor, magnetic separation magnetization, etc.
