NdFeB Permanent HCB 4.94 Magnetic Compound Rare Earth Magnet Compound

HCNT-240 HCB 4.94 Magnetic Compound

What are NdFeB compounds?

Neodymium-iron-boron compound is the most widely used type of rare earth magnet compound. 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.

NdFeB compounds have excellent magnetic properties and are widely used in electronics, motors, medical devices, toys, packaging, hardware machinery, aerospace and other fields. More common are permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment and instruments.

Nano (Royce3010) chelated film without coating treatment 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 more 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 and military industries, etc.

Process flow

• 1. Use NdFeB magnetic powder to mix with PA6 or PA12 or PPS or EPA, antioxidants and lubricants, and form pellets in a screw extruder
• 2.The granules are sieved and weighed, and the properties are measured and then packed into buckets or bags, and packed on pallets

Application

• Injection molding NdFeB compouds are a kind of bonded NdFeB products, and are suitable for products formed by injection molding machines. Because of the high precision of injection molding and integrated molding with copper, stainless steel, plastic bearings and other types of inlays, It can be used in micro motors, motor rotors and sensors, automotive motors, and can also be used in household appliances and toys
• The properties of anisotropic PPS NdFeB pellets are close to that of molded NdFeB magnets and can be used for high-performance magnets. At the same time, PPS has a temperature resistance of 200 degrees and is resistant to acid, alkali and salt environments.

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.
