NdFeB Magnets / Neodymium Iron Boron Magnets Datasheet NdFeB magnets are also know as Neo Neodymium Iron Boron NdBFe NIB Super Strength and Rare Earth Magnets (although SmCo also shares this term) This data sheet covers the standard production 55 range of NdFeB magnets (currently 55 grades) that are commonly in use They are used in nearly all Industries:- Automotive Aerospace
The formula can only be used with straight-line demagnetization curve materials - i e for rare earth and ferrite materials - and where the magnet length L m is kept within the bounds of normal standard magnet configurations 5 0 Permanent Magnet Stability
A neodymium magnet (also known as NdFeB NIB or Neo magnet) is the most widely used type of rare-earth magnet It is a permanent magnet made from an alloy of neodymium iron and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure Developed independently in 1984 by General Motors and Sumitomo Special Metals neodymium magnets are the strongest type of permanent magnet
a permanent and stable supply system for low-cost high-power magnet materials We have established a mass-production/supply system for a completely Dy-free material that is compa- rable to the Dy-added NEOREC 55 series which has achieved the world's highest level maximum energy product Meanwhile we have also developed our unique High Anisotropy field Layer (HAL) production process which
General Magnetic Materials covers electrotechnical vocabulary to the properties of magnetic materials at elevated temperatures Knowing how to handle magnetic materials and understanding their properties is important so that they work as intended These general standards for magnetic materials can provide the proper means to appropriatly work these materials
Motors and rare-earth magnetic materials by Jim Harrison Permanent magnet materials The price rise has generated new interest in mining at locations in California Nebraska Malaysia and Africa Additional recycling facilities are also starting up in a number of countries The world's largest refinery for rare-earth metals in Kuantan Malaysia is approaching completion The plant
Suspended permanent magnets are an excellent choice for conveyor belts carrying moderate burden depths and belt speeds where electromagnets are not needed These magnets are especially helpful in the removal of larger tramp material where other types of magnetic separators may struggle Manual clean permanent magnets offer an affordable solution when tramp material is infrequent though for

Alnico is a family of iron alloys which in addition to iron are composed primarily of aluminium (Al) nickel (Ni) and cobalt (Co) hence acronym al-ni-co They also include copper and sometimes titanium Alnico alloys are ferromagnetic and are used to make permanent magnets Before the development of rare-earth magnets in the 1970s they were the strongest type of permanent magnet
The magnetic properties of all magnet materials are reduced at elevated temperatures The magnetic properties of different magnet materials decay at different rates and if elevated temperatures are a concern to the user this effect should be evaluated Note in particular that electromagnets which conduct electric current through a coil will generate heat thereby varying the coil resistance
Grades Materials - We carry a large inventory of licensed alnico magnet materials in both standard premium grades for reduced production and lead times We offer both cast and sintered alnico magnets in grades ranging from Alnico 2 to Alnico 5 Alnico 8 Visit our alnico magnet materials page for additional information and data sheets about this material
