A neodymium magnet (also known as NdFeB magnet or Neo magnet), a type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. This material is currently the strongest type of permanent magnet, also called a supermagnet. There are two principal Neodymium magnet manufacturing routes:
The classical powder metallurgy or sintered magnet route
Sintered Neo magnets are prepared by pulverizing an ingot precursor and liquid phase sintering the magnetically aligned powder into dense blocks which are then heat treated, cut to shape, surface treated and magnetized. Currently, between 45,000 and 50,000 tons of sintered neodymium magnets are produced each year, mainly from China and Japan.
The rapid solidification or bonded magnet route
Bonded Neo magnets are prepared by melt spinning a thin ribbon of the Nd-Fe-B alloy. The ribbon contains randomly oriented Nd2Fe14B nano-scale grains. This ribbon is then pulverized into particles, mixed with a polymer and either compression or injection molded into bonded magnets. Bonded magnets offer less flux than sintered magnets but can be net-shape formed into intricately shaped parts and do not suffer significant eddy current losses. There are approximately 5500 tons of Neo bonded magnets produced each year. In addition, it is possible to hot press the melt spun nanocrystalline particles into fully dense isotropic magnets, and then upset-forged/back-extruded these into high energy anisotropic magnets.
What else can I help you with?
Why are super magnets called super magnets?
They call them that because they are able to lift a lot of metal.
What stops the pulling power of magnets?
I dont think you can ---- If you super-heat the magnets, it will demagnetize them, thus stopping the "pulling power" of the magnets. Basically stick the magnets in a vat of super boiling water, that should be sufficient enough heat to demagnetize the magnets.
Are all magnets metal?
Not all magnets are made of metal. There are various types of magnets, including ceramic magnets (made of ferrite), neodymium magnets (made of neodymium, iron, and boron), and even electromagnetic magnets that are not made of metal.
What are the uses of super magnets?
Super magnets are used to help produce sound in speakers. They also help pick up vibrations in electric and bass guitars. These magnets come in many different forms.
What attracts magnets and is made out of magnets?
magnetism
How do you levitate a ball?
. use super magnets or something...
How can magnets change?
magnets can be made destroyed or broken apart
Is magnet use in iron?
Magnets is made of iron. Magnets are attracted to anything made out of iron.
What are today's magnets made from?
todays magnets are made of alloys yahoo answered this question too. :)
What is a buckey ball made of?
its made out of magnets
What is made with neodymium?
Magnets.
What are magnets and artificial magnets?
since magnets are all ready magnetised when found in nature called natural magnet artificial magnets that are made by man are called artificial magnets
