HCNTP-35BL Density 4.67 Instrumentation NdFeB Compound
NdFeB Compound
NdFeB compounds have high-quality magnetic houses and are broadly
utilized in electronics, motors, clinical devices, toys, packaging,
hardware machinery, aerospace and different fields. More not
unusualplace are everlasting magnet motors, speakers, magnetic
separators, pc disk drives, magnetic resonance imaging device and
instruments.
Neodymium-iron-boron compound is the maximum broadly used form of
uncommon earth magnet compound. It is a everlasting magnet product
of an alloy of neodymium, iron and boron, forming a tetragonal
crystal shape of Nd 2 Fe 14 B.

Characteristics
NdFeB everlasting magnet cloth is primarily based totally on
intermetallic compound Nd2Fe14B. NdFeB has very excessive magnetic
electricity product and coercive force, at the same time as the
blessings of excessive electricity density make NdFeB everlasting
magnet cloth extensively utilized in cutting-edge enterprise and
digital technology, which makes it feasible to miniaturize, lighten
and skinny the gadget of instrumentation, electroacoustic motor,
magnetic separation magnetization, 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.
