Aleaciones de níquel y cobalto
Las Aleaciones de níquel y cobalto son materiales metálicos cuyas propiedades se desarrollan mediante sistemas de aleación de níquel, de cobalto o combinados. Se caracterizan por una elevada resistencia a la corrosión, la oxidación y el desgaste, así como a la pérdida de resistencia a temperaturas elevadas, por lo que son adecuadas para componentes de turbinas, equipos de transformación química y otras aplicaciones exigentes de alta temperatura.
