Neodymium iron boron magnet discs so cow, its material composition of how? Please see the back of decomposition:
Is expected in the next 20 years, the emergence of magnetic material may not have the alternative of neodymium iron boron magnet. The main raw material for the production of neodymium iron boron magnet of rare earth neodymium metal, rare earth praseodymium metal, iron, aluminum, boron iron alloy and other rare earth materials.
Advantages of neodymium iron boron magnet wafers:
Neodymium iron boron magnet wafers are cost-effective, with good mechanical properties; the shortage is that the Curie temperature point is low, temperature characteristics is poor, and easy powder corrosion, must surface treatment method by adjusting the chemical composition and taken to make improvements, in order to meet the requirement of practical application. Neodymium iron boron belongs to the third generation rare earth permanent magnetic materials, has the advantages of small volume, light weight and strong magnetism characteristic, is currently the best cost performance magnet in the magnetic field is known as magnetic wang. The advantages of high energy density of the Nd-Fe-B permanent magnetic materials have been widely used in modern industry and electronic technology. In the bare magnetic state, the magnetic force can reach 3500 around Gauss.
