Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal formed by neodymium, iron and boron (Nd2Fe14B). In 1982, Sumitomo Sasakawa found neodymium magnet. The magnetic energy product (BHmax) of this magnet is larger than that of SmCo magnet, which was the largest material in the world at that time. Later, Sumitomo special metals successfully developed the powder metallurgy
The invention relates to an antioxidant for milling a neodymiumironboron alloy. For the first time, the antioxidant for milling the neodymiumironboron alloy accounting for % of the weight of the coarse powder is added, and for the second time, the antioxidant accounting for % of the weight of the coarse powder is added, wherein the antioxidant is composed of such
Neodymium is a chemical element with the symbol Nd and atomic number 60. Neodymium belongs to the lanthanide series and is a rareearth is a hard, slightly malleable silvery metal that quickly tarnishes in air and moisture. When oxidized, neodymium reacts quickly to produce pink, purple/blue and yellow compounds in the +2, +3 and +4 oxidation states.
Neodymium Iron Boron magnets are a type of rare earth alloy that typically has two atoms of Neodymium (Nd), 14 atoms of Iron (Fe), and one atom of Boron (B) as its primary elements, hence their chemical composition Nd 2 Fe 14 B, which is commonly abbreviated as NdFeB. There are other elements that are used to increase the coercivity, to gain lower oxidation characteristics, and to obtain other

They are permanent magnets ( they generate their own magnetic field) made from an alloy of the metallic elements neodymium, iron and boron. As the strongest commerciallyavailable magnet, they can lift objects many times their own weight and are widely used as positioning, pulling and clamping components in sectors such as engineering, manufacturing, education, research and industry.
neodymium iron powerful. An alloy of neodymium, iron and boron discovered in the s is ferromagnetic, yielding permanent magnets over times stronger than anything ever seen before neodymium ion borade magnets have not only found their way into almost billions of electric motors and electronic devices around the world but also into wonderful toys for children
neodymium iron milling machine . Neodymium Iron Boron is a rare earth magnetic alloy that is most commonly sintered into blocks or discs. Bonded neodymium iron boron magnets, which are produced by combining magnetic powder with a nonmagnetic binder are easily machined but only produced in lower energy densities.
