Imanes de alta temperatura |
|
|
Los imanes de alta temperatura pueden trabajar a temperaturas muy altas sin perder fuerza magnética
|
Imanes de alta temperatura:Se les llama así a los imanes que trabajan a temperaturas muy altas sin pérdida de fuerza magnética. Los imanes de tierra rara AlNiCo son los que trabajan a la más alta, entre 450-550ºC. Tambien tenemos otros imanes de tierras raras, como los de NdFeB y SmCo. Los imanes de NdFeB sintetizados pueden trabajar a temperaturas de 200ºC, mientras que los imanes de tierra rara de SmCo pueden trabajar entre 250-350°C. |
