Est\u00e1n disponibles comercialmente desde noviembre de 1984. Se jactan de ofrecer el producto de mayor energ\u00eda (de todos los materiales\/imanes actuales) y est\u00e1n disponibles en una amplia variedad de tama\u00f1os, calidades y formas (discos, arcos, bloques, esferas, trapecios, etc.).<\/p>\n<p>Inicialmente, los imanes de NdFeB se utilizaban principalmente para fabricar motores de bobina m\u00f3vil (VCM) en unidades de disco duro. Esta aplicaci\u00f3n a\u00fan representa aproximadamente el 55 % de las ventas totales de imanes de NdFeB sinterizado. Estos imanes tienen muchas otras aplicaciones gracias a su precio razonable y sus propiedades magn\u00e9ticas superiores. Los imanes de NdFeB se utilizan en la fabricaci\u00f3n de numerosas herramientas y equipos, como herramientas de comunicaci\u00f3n, dispositivos inform\u00e1ticos, motores, sensores, altavoces e instrumentos de tratamiento m\u00e9dico, por mencionar solo algunos.<\/p>\n<p>Los imanes de NdFeB sinterizados se fabrican utilizando un compuesto intermet\u00e1lico, el Nd\u2082Fe\u2081\u2082B, compuesto por dos \u00e1tomos de tierras raras, un \u00e1tomo de boro y catorce \u00e1tomos de hierro. Adem\u00e1s de la fase principal, el Nd\u2082Fe\u2081\u2082B (en los materiales de NdFeB), existen peque\u00f1as cantidades de fase rica en Nd (fase rica en tierras raras), fase rica en boro y otras. La fase rica en tierras raras fija las paredes del dominio, lo que confiere a los imanes de NdFeB sinterizados una alta fuerza coercitiva. Los imanes de NdFeB disponibles comercialmente en la actualidad presentan numerosas combinaciones de sustituci\u00f3n de Nd y Fe con aleaci\u00f3n parcial, lo que resulta en diversas propiedades. Adem\u00e1s, la mayor\u00eda de los imanes son anisotr\u00f3picos, lo que significa que pueden magnetizarse en la direcci\u00f3n de orientaci\u00f3n. Los imanes de neodimio son de tercera generaci\u00f3n.\u00a0<b><a href=\"http:\/\/www.magnet-ndfeb.com.\/rare-earth-magnet.html\">imanes de tierras raras<\/a><\/b>\u00a0que son simplemente los imanes m\u00e1s potentes y avanzados comercialmente del mercado actual.<\/p>\n<p><b>Principales ventajas<\/b><br \/>\nLos imanes de NdFeB sinterizado emiten campos magn\u00e9ticos muy profundos que atraen otros imanes y objetos ferrosos desde distancias impresionantes. Estos imanes son extremadamente potentes considerando factores como el tama\u00f1o. Son un ejemplo fiel de lo que pueden hacer los imanes peque\u00f1os y potentes. Los peque\u00f1os imanes de NdFeB sinterizado poseen una fuerza magn\u00e9tica inigualable. Por ejemplo, son capaces de levantar imanes\/metales que pesan 1000 veces su propio peso.<br \/>\nSeguro que te sorprender\u00e1 la resistencia de los imanes de NdFeb sinterizados si no los has manipulado.\u00a0<b><a href=\"http:\/\/www.magnet-ndfeb.com.\/sintered-neodymium-magnet.html\">imanes de neodimio<\/a><\/b>\u00a0Los imanes son 10 veces m\u00e1s potentes que los de ferrita, que son los imanes cer\u00e1micos m\u00e1s potentes. Otra ventaja notable de los imanes reside en su variedad de formas, siendo las m\u00e1s comunes las de bloque, anillo y disco. Tambi\u00e9n es posible personalizarlas. Adem\u00e1s, ofrecen otras ventajas, como su excelente fuerza coercitiva, sus altas remanencias y su brillante rendimiento energ\u00e9tico.<\/p>\n<p><b>Principales desventajas<\/b><br \/>\nAunque los imanes de neodimio ofrecen numerosas ventajas, tambi\u00e9n presentan algunas limitaciones. En primer lugar, son susceptibles a la corrosi\u00f3n. Sin embargo, es importante tener en cuenta que un recubrimiento protector es suficiente para solucionar este problema eficazmente. En la mayor\u00eda de los casos, los imanes de NdFeB sinterizado se recubren con un recubrimiento triple de NiCuNi (n\u00edquel-cobre-n\u00edquel), epoxi en aerosol electrost\u00e1tico seco y zinc.<br \/>\nLos imanes de NdFeB sinterizados tambi\u00e9n presentan una alta densidad, lo que los hace extremadamente fr\u00e1giles. Por lo tanto, deben utilizarse con precauci\u00f3n.<br \/>\nLos imanes de NdFeB sinterizados tambi\u00e9n tienden a perder su magnetismo r\u00e1pidamente al exponerse a altas temperaturas de funcionamiento, superiores a la temperatura m\u00e1xima de funcionamiento de 230 \u00b0C. Sin embargo, cabe destacar que los numerosos cambios en la composici\u00f3n y el procesamiento de los imanes de NdFeB sinterizados en los \u00faltimos a\u00f1os han mejorado considerablemente su rendimiento a altas temperaturas y su resistencia a la corrosi\u00f3n.<\/p>\n<p><img decoding=\"async\" class=\"lazyload\" data-src=\"https:\/\/www.cndailymag.com\/media\/144\/79%281%29_1.jpg\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" \/><noscript><img decoding=\"async\" src=\"https:\/\/www.cndailymag.com\/media\/144\/79%281%29_1.jpg\"><\/noscript><\/p>","protected":false},"excerpt":{"rendered":"<p>Los imanes de NdFeB sinterizado (tambi\u00e9n conocidos como imanes &quot;neo&quot;) se encuentran entre los m\u00e1s populares del mercado actual.
