Rare-earth Consumption Uses in Neodymium Magnets
Rare-earth Consumption Uses in Neodymium Magnets - Rare-earth elements (REEs) are also known as the lanthanide series in the periodic table of elements. They are not particularly rare in terms of abundance, but for many years remained rarely separated from each other due to their similar chemical characteristics. Rare earth elements are widely used in mature markets (such as catalysts, glassmaking, lighting, and metallurgy) and in newer high-growth markets (such as battery alloys, ceramics, and permanent magnets. In mature market segments, lanthanum and cerium constitute about 80% of rare earth elements used, and in new market segments, Dysprosium, Neodymium and Praseodymium account for about 8% of rare earth elements used.

How does a magnet work?
How does a magnet work? Atomic structure Magnetic atom: protons with north and south poles, electrons with north and south poles, and neutrons The way a magnet works is determined by its overall atomic structure. Every atom is made up of negative electrons circling around positive protons and neutrons (called a nucleus), which are effectively microscopic magnets with north and south poles. The electrons of a magnet move around the protons to create an orbital magnetic field. Magnets have what is known as a half shell of electrons; in other words, they are not paired up like other materials. These electrons then line up, which creates a magnetic field. All atoms align in groups which are known as crystals. The ferromagnetic crystals then align themselves to their magnetic poles. In a non-ferromagnetic material, on the [...]
Neodymium Magnet Manufacturing Methods
Neodymium Magnet Manufacturing Methods, Sintered Neodymium Iron Boron Magnets, Bonded Neodymium Magnets Sintered Neodymium Iron Boron Magnets: The sintered Neodymium Iron Boron magnet is produced by the OPS (orient-press-sinter) method. A crystalline alloy of Neodymium, Iron, and Boron is ground to a sub-micron powder using a ball mill, then aligned in a strong magnetic field, and pressed into a basic shape. The resultant "block" is then sintered, thereby fusing the material into a solid metal. Bonded Neodymium Magnets: The bonded Neodymium Iron Boron materials are typically anisotropic. They can be made isotropic, and are manufactured using "binders," such as epoxy resins or nylon to hold the powder in place, rather than "sintering" the alloy. Energy products of the bonded magnet range from 5 MGOe to 10 MGOe. Two basic processes are used: Compression Molding Binders [...]

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 [...]

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.
