Magnet Manufacturer: NdFeB How made? Sintered NdFeB powder metallurgy manufacturing process is an iron-based permanent magnet material. The main steps are: formula, melting, milling, molding orientation, sintering, machining, plating processing. Control wherein the oxygen content is an important indicator of the level of workmanship. The new production plant Tong Company has selected high-vacuum melting, sintering furnace and advanced automatic control jet mill common rectangular sheet magnets to ensure that the basic production process anaerobic operation, so that product performance and temperature are breakthrough improvements. 1. Q: The magnetic energy NdFeB magnets can for how long? A: NdFeB magnets have demagnetization and will not change under a high magnetic coercivity, the natural environment and the general magnetic field. It assumes that the ambient proper rectangular sheet magnets wholesale, even after prolonged use rectangular sheet magnets, magnetic magnets loss will not be great. So easy to use in practical applications rectangular sheet magnets, we tend to ignore the impact of time on the magnetic properties. 2. Q: magnet verticality, parallelism and roundness respectively? A: For example the outer diameter of the inner annular magnet D10-D30mm range verticality: 0.15mm Parallelism: 0.10mm roundness: 0.15mm outer diameter D30-D60mm verticality within the range: 0.20mm Parallelism: 0.15mm roundness : 0.20mm above is generally standard, any special requirements please specify in the order.
