FUSiO2N<\/a>\u2122<\/a>\u00a0SP de Rex Materials est\u00e1 especialmente formulado para los tapones que se utilizan en las m\u00e1quinas de fundici\u00f3n de billones de Wagstaff. FUSiO2N SP es una composici\u00f3n sinterizada de s\u00edlice f\u00falvica de gran finura que proporciona propiedades de desgaste excepcionales y una excelente resistencia al choque t\u00e9rmico. Suas propiedades especiales de no humectaci\u00f3n, adem\u00e1s de su revestimiento con nitruro de boro en f\u00e1brica, evitan el pegado del metal y la acci\u00f3n de los metales fundidos como el aluminio y otros metales fundidos. FUSiO2N SP ha aprobado todos los principales ensayos de resistencia al aluminio especificados por los principales fabricantes de aluminio.<\/p>\n

La menor masa t\u00e9rmica y la conductividad minimizan la posibilidad de congelamientos durante la puesta en marcha o a bajas velocidades de flujo del metal. Nuestro proceso especial FUSiO2N SP nos permite ofrecer esta excepcional performance a un precio muy razonable. Nuestro proceso ha sido dise\u00f1ado de forma que la superficie de contacto met\u00e1lico interior de nuestros tapones no tenga pr\u00e1cticamente ninguna porosidad.<\/p>\n

Los ensayos realizados por el cliente concluyen que FUSiO2N SP dura m\u00e1s tiempo que los tapones de s\u00edlice f\u00fandida tradicionales. \u00a1Estamos tan seguros de que quedar\u00e1n satisfechos con el rendimiento que ofrecemos que ofrecemos una garant\u00eda de devoluci\u00f3n de dinero!<\/p>\n
