Sintered NdFeB magnets are made by compacting and heating a mixture of neodymium, iron, and boron powders. This process results in a very strong and high-performance magnet. Bonded NdFeB magnets are made by mixing NdFeB powder with a polymer binder, which allows for complex shapes but with lower magnetic properties compared to sintered magnets.
What else can I help you with?
What is the second strongest magnet?
The second strongest magnet known is a type of neodymium magnet, specifically the NdFeB (neodymium-iron-boron) magnets, which have a maximum energy product (BHmax) of up to around 52 MGOe. These magnets are widely used in various applications, from electric motors to magnetic resonance imaging (MRI) machines. The strongest permanent magnet, however, is typically a specialized type of samarium-cobalt magnet, which surpasses neodymium magnets in terms of temperature stability and corrosion resistance.
What is a sintered funnel?
A sinterd funnel is simply a funnel with a built in filter. The filter is sintered, I think that this means that small particles are compressed together (and heated ?) to form a single piece of material with many small holes. The sintered funnels I use are made of glass, a link to some images is below (not mine). http://curlyarrow.blogspot.com/2008/01/how-to-clean-your-sintered-funnel.html I have also used sintered polyethylene and sintered stainless steel for filtering.
What is the magnetic strength of a hard drive magnet?
The magnetic strength of a hard drive magnet typically ranges from 300 to 1,500 gauss, depending on the type of magnet used, usually neodymium-iron-boron (NdFeB) magnets. These magnets are strong enough to hold the read/write heads in place and ensure reliable data storage. However, while they are powerful for their size, they are not as strong as industrial magnets used in other applications.
What kind of filter paper is used in sintered glass crucible?
Sintered glass crucibles typically use a type of filter paper known as "sintered glass filter discs" or "sintered glass filters." These filters are made from finely powdered glass that is sintered to form a porous structure, allowing for the filtration of fine particles while maintaining chemical resistance. They are commonly used in laboratory applications for filtration, drying, and other processes where durability and purity are essential.
Are alnico magnets the most powerful magnet?
No, alnico magnets are not the most powerful type of magnet. While they are known for their high temperature stability and resistance to demagnetization, the most powerful permanent magnets are neodymium magnets (NdFeB). Neodymium magnets offer significantly higher magnetic strength and energy density compared to alnico magnets, making them the preferred choice for many high-performance applications.
How are super magnets made?
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 routeSintered 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 routeBonded 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 are some other names for a neodymium magnet?
Some other names include NdFeB, Neo, or Nib. This is also known as a rare-earth magnet and they have the potential to store large amounts of magnetic energy. Several different websites sell these - one is Applied Magnets.
What are the strongest magnets other than super conducting magnets?
NdFeB neodymium magnets are the strongest magnet with the highest magnetic performance and coercive force in the world. Neodymium NdFeB magnet has excellent magnetic property and extremely strong for its small size. NdFeB magnet is more sensitive to temperature changes, ranging from 0.10%/°C - 0.13%/°C. NdFeB magnet is the permanent magnets with highest maximum energy product. Over the last 10 years, due to high ratio of performance over price of the NdFeB magnet, NdFeB magnet has become extremely popular in almost all high technology applications that require high performance magnets, motors, sensors, computers, communications, medical equipment, meters, home appliances and so on.
