80-200um Rare Earth Magnetic Powder Silver Bonded NdFeB Powder

MGT-13-09 80-200um Rare Earth Magnetic Powder

Product Introduction

Rare earth magnetic powders are robust everlasting magnets made from uncommon earth detail alloys. Rare-earth magnets, evolved within the Seventies and 1980s, are the most powerful sort of everlasting magnets ever manufactured, generating a great deal more potent magnetic fields than different forms of magnets consisting of ferrite or alnico magnets. Rare earth magnets commonly generate fields in extra of 1.2 Tesla, at the same time as ferrite or ceramic magnets commonly generate fields among 0.five and 1 Tesla.

Neodymium Magnet Features

Neodymium magnets are extremely high flux magnets and provide the highest energy product of all common prior art magnets. These magnets also have high mechanical resistance, which makes them superior to samarium cobalt magnets in a range of magnetic applications.
Certain key aspects of these magnets, such as their tendency to corrode, have now been largely replaced by new technologies. The newest grades of new NdFeB magnet alloys are nearly as resistant to irreversible losses from high temperatures as Samarium Cobalt magnets.
Bonded plastic neodymium magnets combine the typical advantages of sintering with the extreme flexibility of the shape.

The Process

The molten NdFeB alloy is sprayed onto the cooling rollers at a certain speed and instantly solidifies to form a thin strip of 0.02-0.05mm thickness. During the rapid cooling process, Nd2Fe14B structure is formed, and finally the thin strip is broken into powder

Common Applications For Rare Earth Magnets Include

Computer hard disk drives

Wind turbines

Speakers/headphones

Bicycle generators

MRI scanners

Fishing reel brakes

Permanent magnet motors in wireless tools

High performance AC servo motors

Traction motors and integrated starter generators in hybrid and electric vehicles

Mechanically powered flashlights that use rare earth magnets to generate electricity in a cranking or rotating (hand crank driven) motion

Industrial applications, such as maintaining product purity, equipment protection and quality control

Trapping of fine metal particles in lubricating oils (crankcases of internal combustion engines, but also gearboxes and differentials) to stop the circulation of said particles so that they cannot cause wear in moving machine parts

We can provide you with a variety of magnetic powders: ferrite, Alnico, NdFeB and SmCo powders.

(1) Magnetic ferrite powder is suitable for wet or dry pressing production process to produce different grades of hard ferrite magnets. According to customer's needs, we can provide different particle size of ferrite powder, ferrite powder can be divided into isotropic ferrite powder and anisotropic ferrite powder.

(2) Alnico magnetic powder is made from Alnico magnets crushed into the required particle size. The characteristic is the small temperature coefficient of Br. This powder is mainly used as raw material for bonded magnets, plastic magnets; various samarium cobalt fault detection; magnetic printing and other high temperature sensitive fields.

3) NdFeB powder can be used in automotive industry, office automation, automobiles. DC brushed motors. Multi-pole stepper and spindle motor applications. Magnetic coatings, magnetic printable substrates, magnetic films, medical diagnostics and therapeutics, video tapes, copying toner, fingerprint recognition, sensors, fuel injectors, permanent magnets, nanoscale fluid seals, electric toys and magnetically cured products.

4) Samarium Cobalt Powder Samarium Cobalt Powder Samarium Cobalt Magnetic Powder Rare Earth Magnetic Powder Used to produce polymer bonded samarium cobalt magnets by compression molding.
