Résistance à la rupture, résistance aux chocs, résistance à la flexion - propriétés mécaniques du NdFeB fritté
Sintered NdFeB Magnet Sintered NdFeB (Neodymium Iron Boron) magnets are among the strongest permanent magnets available today. They are made through a powder metallurgy process, where neodymium, iron, and boron powders are mixed together, compacted in a mold under high pressure, and then sintered at high temperatures. These magnets have exceptional magnetic properties, including high […]
Matériaux magnétiques dans les haut-parleurs
Speaker magnets are a crucial component in most speakers speaker magnet responsible for creating the magnetic field necessary for the speaker to function. Typically, they’re made of materials like ferrite (ceramic), neodymium, or even samarium-cobalt. These magnets interact with the electric current flowing through the voice coil, which in turn causes the speaker cone to […]
