Neodymium Iron Boron Magnet Material Overview Neodymium Iron Boron (NdFeB) magnets were commercially introduced in the early 1980s, and are widely used today for many different applications. The cost of neodymium magnet material (on a dollar per energy product basis) is comparable to that of ferrite magnets. * NdFeB magnets are covered by various patents [...]
NdFeB Magnets General Information Collectively known as Rare Earth magnets, Neodymium Iron Boron (NdFeB) and Samarium Cobalt (SmCo) magnets are alloys of the Lanthanide group of elements. Rare Earth magnets are the most advanced commercialized permanent magnet materials today. NdFeB magnets are available in a number of different grades that span a wide range of [...]
Neodymium Magnet Description The tetragonal Nd2Fe14B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy (HA~7 teslas - magnetic field strength H in A/m versus magnetic moment in A.m2). This gives the compound the potential to have high coercivity (i.e., resistance to being demagnetized). The compound also has a high saturation magnetization (Js ~1.6 T or [...]
High Temperature Magnet - We have developed new magnet for high temperature application! Neodymium magnet is with much higher Br than any other magnets such as AlNiCo, Sm-Co etc, but it also has a disadvantage, that its maximum working temperature and temperature stability are much worse than other magnetic materials, which directly restrict the wide [...]
Adhesive strong magnet is powerful Neodymium magnet with high quality 3M adhesive backing and a new, easy-pull tab. The neodymium magnet is Ni-Cu-Ni plated to protect them against corrosion and conventionally magnetized through the thickness. Usually, the magnets exist in two versions per size – the A version has a North Pole face visible; the [...]
adhesive neodymium magnets - As a senior magnet manufacturer, we met some customers who consulted us adhesive for rare earth magnet. Magnets for motors, magnet for loudspeakers and magnet with plastic all need adhesive. Questions like: 1. What adhesive should I use on neodymium magnets? 2. Best adhesive for permanent magnets? 3. Best glue or [...]
Large Magnets and Small Magnets Safety Precautions Large Magnets Warning Big magnets have a very strong attractive force. Unsafe handling could cause jamming of fingers or skin in between magnets. This may lead to contusions and bruises. Larger magnets (more than 0.5 lbs) can easily crush fingers and break bones.
