Neodymium Iron Boron Magnet Material
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 and only licensed materials are allowed into the CHINA.

NdFeB Magnets
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 properties and application requirements.

The bonded form of the material can be produced with close tolerances off tool, with little or no finishing required. The energy product of the bonded form is much lower than that of the sintered form - up [...]
Neodymium Magnet
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 16 kG) and typically 1.3 teslas. Therefore, as the maximum energy density is proportional to Js2, this magnetic phase has the potential for storing large amounts of magnetic energy (BHmax ~ 512 kJ/m3 or 64 MG·Oe). This property is considerably higher in NdFeB alloys than in samarium cobalt (SmCo) magnets, which were the first type of rare-earth magnet to be commercialized. In practice, the magnetic properties of neodymium magnets depend on the alloy composition, microstructure, and manufacturing technique employed. [fusion_builder_container [...]
High Temperature Magnet
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 application of Neodymium magnet in some special fields.

Adhesive Strong Magnet
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 B version has a South Pole face visible (so the A and B versions will stick to each other). South pole or North pole of magnet can be marked with a red dot on the face for easy identification. Another solution is a magnet will attract to a ferromagnetic (e.g. mild steel) material, it achieves perfect alignment with magnet-to-magnet applications, but more economical. The most regular adhesive is 3M 467 adhesive for this product, but if you do require any [...]
What adhesive should I use on neodymium magnets?
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 method for attaching magnets? First, you should get to know your magnet well. 1.Strong Magnetic force, if possible, make a hole to fix magnet 2.Usually Ni coating, very smooth, if possible, get them rough enough 3.Max working temp. (Different grades have different working temp.) , with high temp., magnet will demagnetize. Second, to choose an adhesive, you should pay more attention to the application environment. Different adhesive, the application is different. E.g. Temp. Humidity, Oil condition and so on. You [...]
