NdFeB Magnet Introduction

2018-07-17
NdFeB is simply a magnet. Unlike the magnets we usually see, it is called the “Magnetic King” because of its excellent magnetic properties. NdFeB contains a large amount of rare earth element lanthanum, as well as iron and boron, and its properties are hard and brittle.
Because the surface is highly susceptible to oxidative corrosion, NdFeB must be surface coated. Surface chemical passivation is one of the good solutions.
NdFeB as a kind of rare earth permanent magnet material has a very high magnetic energy product and coercive force, and the high energy density makes the NdFeB permanent magnet material widely used in modern industrial and electronic technology, thus making the instrument It is possible to reduce the size, weight, and thickness of instruments, electroacoustic motors, and magnetic separation magnetization.
The advantages of NdFeB are high cost performance and good mechanical properties. The disadvantages are low operating temperature, poor temperature characteristics, and easy chalking. It must be improved by adjusting its chemical composition and surface treatment. Meet the requirements of practical applications.

NdFeB magnetic materials, as the latest result of the development of rare earth permanent magnet materials, are called "magnetic king" due to their excellent magnetic properties. The neodymium iron boron magnetic material is an alloy of base metal, boron iron or the like. Also known as magnetic steel.

With excellent magnetic properties, it is widely used in electronics, electric machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields. More common are permanent magnet motor, speaker, magnetic separator, computer disk drive, magnetic resonance imaging. Equipment and meters.
Nano (Royce3010) chelating film without coating treatment can meet the requirements of 20-30 years in marine climatic conditions, can be widely used in sea-based wind power generation. Surface bonding force is more than 20Mpa, can be widely used in permanent magnet high-speed motors, special motors, electric motor motors , UHV, high voltage DC power supply system, fast charging system, aerospace military and other fields.
